The Fender '57 Custom Champ 5W

Fender ’57 Custom Champ 5W


The Fender ’57 Custom Champ 5W is an all-tube amplifier with a power of 5W. This iconic amp has been popular for over six decades and continues to delight musicians with its vintage-style design and classic tweed tone. It’s based on the 5F1 circuit, which is known for its snarling tone.

The Fender ’57 Custom Champ is part of Fender’s ’57 reissue series and features a pine cab covered in tweed cloth, a leather handle, chrome-plated steel chassis, and a single 8-inch speaker. The amp uses a Groove Tubes 12AX7 preamp tube, a GT 6V6GT power tube, and a Ruby 5Y3 tube rectifier.

Key Benefits

  • Easy to use: Simply plug in, turn on, and dial up the desired volume and distortion level.
  • Versatile: Offers a wide range of tones, from clean to crunchy blues tones.
  • Compact and Portable: Suitable for home or studio use.
  • Excellent for Recording: Highly regarded for its recording capabilities.
  • Vintage-Style Design: Features a tweed covering, chrome control panel, and leather handle.
  • Collector’s Item: Part of Fender’s ’57 reissue series.


While the amplifier is usually priced around $1060.00, it can vary depending on the retailer. The Fender ’57 Custom Champ is generally more expensive than other Fender models such as the Fender Blues Junior IV and the Fender Pro Junior IV, and cheaper than the Fender 64 Custom Princeton Reverb and the Fender 57 Custom Deluxe.

Pros & Cons

Coming from a personal standpoint, the Fender ’57 Custom Champ has a range of notable pros. It’s a fantastic clean pedal platform and offers an impressive clean tone. Being hand-wired, it has a high price point, but that’s attributed to its quality and craftsmanship. The 12AY7 preamp and the 6V6 power tube give the amp a big and full sound that’s hard to resist.

The amp is designed to stay clean at lower volumes but can also be cranked up for a dirty tone. Its simple design, with only one volume control and no tone controls, adds to its appeal. Known for being used on classic albums, including the Layla album, it certainly has a rich history.

When tested with delay and overdrive pedals, the amp demonstrated its ability to handle pedals well. However, it might not handle high volumes and low-end frequencies as well due to its small speaker size. It’s been noted that when the amp is turned up too far, it can become harsh and have an excessive top end. The amp’s sweet spot is found at a volume setting between 4 and 6.5, where it delivers a musical tone.

However, despite its many pros, there are a few cons to consider. Although it’s a great little amp with a plug-and-play design, it may be considered overpriced for what it offers. But overall, its rich history and use on many classic albums add to its appeal.

The Vox AC15C1 15W

Vox AC15C1 15W


The Vox AC15 C1 is a vintage-looking tube amp that is iconic in the music world. As a tube amp, it requires power transformers that are heavy due to their magnets and plates. This 15 Watt guitar amplifier comes with a 12” Speaker, which is larger than those found in many similar Wattage amplifiers.

It features dual-channel input, a typical channel, and a top boost channel. The top boost channel, in particular, offers EQ controls for bass and treble. However, it does lack mid-range controls. It is best suited for British rock, Classic rock, and dirty bluestone and is not ideal for metal genres or beginner guitarists.

Key Benefits

  • Classic, vintage look and feel
  • High-quality sound, representative of the Vox brand
  • Large 12” Speaker for enhanced sound quality
  • Dual-channel input with top boost channel for advanced sound shaping
  • Ideal for British rock and Classic rock genres
  • Offers beautiful sparkling cleans and a good choice for dirty bluestone


The Vox AC15 C1 is a high-quality tube amp, and as such, it falls within the higher end of guitar amp pricing. Its price is reflective of the vintage allure, sound quality, and brand reputation it brings to the table.

Pros & Cons

From the research I’ve done, the Vox AC15C1 15W is often referred to as a legendary amp, the little brother to the more famous AC30. It’s known for its classic Vox tone and versatility, which is something users often praise. The amp comes in two variants: the Greenback version and the Alnico Blue version. Both are great for home use and even for stadium performances, depending on your needs.

One of the most appreciated features of the amp is its built-in spring reverb and tremolo. Many users regard it as one of the best in the industry, giving you that unique bloom sound when playing chords. The amp has two channels: a normal channel and the famous top boost channel. The normal channel has a volume control, while the top boost channel has a volume control and a two-band EQ. This allows for a wide range of tones, from clean to overdriven, at both low and high volumes.

However, despite its many positive aspects, it’s worth noting some potential drawbacks. Although it is a versatile amp, it appears to be brighter compared to other brands such as Fender and Marshall. Also, it lacks mid-range controls which could be an issue when playing with a band, as this would offer more flexibility for the guitarist. Lastly, it’s not an amp designed for beginners due to its complex features and price point. If you’re just starting your guitar journey, you might want to consider something more budget-friendly and suitable for beginners.

The Marshall SV20H Studio Vintage

Marshall SV20H Studio Vintage

  • Power reduction technology for use at lower volumes without sacrificing tone
  • Handcrafted in the UK with three ECC83 preamp tubes and two EL34 power amp tubes
  • Compatible with the matching Studio Vintage 1×12 cabinet, which features a Celestion V-Type speaker


The Marshall SV20H Studio Vintage is available for purchase at a price of roughly $759.

Pros & Cons

As someone who’s spent a good amount of time with the Marshall SV20H Studio Vintage, it’s evident that this amp offers classic Marshall tones in a manageable format. Based on the classic 1959SP, the SV20H boasts tubes for its preamp and power sections, contributing to its authentic sound.

The front panel of the SV20H features a 4-input configuration with high and low sensitivity inputs for both normal and high treble channels. Players have the flexibility to adjust volume knobs for each input, a 3-band EQ section, and presence control. Notably, there are switches for on/off and for selecting between 20-watt full power, 5-watt low power, or standby mode.

On the back panel, you’ll find various output options for different load configurations, a D out for direct recording, and an effects loop. This versatility is a big advantage for musicians who like to experiment with different sounds and setups. The amp works great with pedals and offers a range of tones from clean to overdriven. It’s worth noting though, while it gives a nice clean sound, pristine clean tones may not be its strongest suit.

One of the standout features of the SV20H is its power flexibility. It can be run at either 20 watts or 5 watts, with the lower wattage option providing a less squishy feel. When cranked up, the SV20H can produce a healthy amount of gain, but it also cleans up nicely when the volume is rolled back.

This amp is not only versatile in terms of its tones but also in the types of guitars it can accommodate. Whether it’s a Gibson Les Paul or a Stratocaster, the SV20H can deliver a range of tones from the bridge to the neck pickup. This makes it a suitable choice for a wide variety of guitar players.

The Mesa Boogie Mark Five 25 guitar amp

Mesa/Boogie Mark Five:25


The Mesa/Boogie Mark Five:25 is a powerful and versatile tube amp that is recognized for its modern and intense sound. This amp is particularly popular among heavy rock and metal players, thanks to its aggressive gain and heavy lows. It boasts of two channels each with its own volume and gain controls as well as a four-band EQ.

With a wide range of clean tones on offer, the clean channel can deliver anything from a warm and scratchy to a bouncy and glassy tone. The second channel incorporates the best gain circuits from various Mesa/Boogie amps including the Mark IIC+, Mark IV, and Mark V.

This amp, with its built-in speaker emulator and headphone output, is an ideal choice for recording or practicing without a speaker cab. It comes in both a combo and head format, offering convenience and portability.

Key Benefits

  • Built-in CabClone speaker-emulated direct output for silent recording or practice
  • Offers incredible versatility with Mesa’s iconic five-band graphic EQ for further tone shaping
  • Wattage selector for each channel, allowing for 25 or 10 watts per channel


The Mesa/Boogie Mark Five:25 is priced at around $1900. While this puts it on the higher end of the price spectrum, it is still considered more affordable compared to other Mesa/Boogie amps in the Mark series.

Pros & Cons

Speaking from a user’s perspective, the Mark Five:25 is a 25-watt amplifier that has received a lot of positive feedback for its performance. One feature of this amp that stands out is its quiet operation. It is an excellent practice amp that won’t disturb neighbors or even individuals in the next room. However, it isn’t without its minor drawbacks. For instance, the fan that kicks on can be a point of contention for some users as it cannot be turned off.

When it comes to performance, the Mark Five:25 holds its own against popular amps like the Peavey 5150 and the Mesa/Boogie Rectifier. Each of these amplifiers has unique qualities, but they are all great in their own way. The clean channel of the Mark Five:25 is widely praised for its warm tone, while the distortion is highly regarded for its raw and powerful sound. Even at low volumes, this amp outperforms the Rectifier and the 5150 in terms of fullness of sound and quietness.

Specifically, the Mark Five:25 excels in heavy metal and dream theater-style playing, thanks to its ability to deliver a wide range of tones. However, to new users of the Mark series amplifiers, this amp can be a bit overwhelming. It’s suggested that you read the manual or look for online resources to familiarize yourself with its features. Once mastered, however, it delivers exceptional performance.

The Fender ’65 Princeton Reverb guitar amp

Fender ’65 Princeton Reverb


First introduced in 1964, the Fender ’65 Princeton Reverb has gained popularity among professional musicians and studios over the years. This combo amp is well-loved for its rich and sweet sound, with a clean Fender tone that can be easily balanced with the EQ controls.

The Fender ’65 Princeton Reverb features a 12-watt power output and is loaded with a single 10″ or 12″ speaker, depending on the model. The amp’s construction is solid, and the design classic, available in finishes of black, tweed, and brown grille cloth.

The Fender ’65 Princeton Reverb is more affordable than some of its counterparts in the market, such as the Fender ’65 Princeton. Despite its compact design and reduced tweaking options, this amp stands strong with its unique pristine Fender output.

Pros & Cons

From what I’ve gathered, the Fender ’65 Princeton Reverb is highly praised for its vintage authenticity and tonal versatility. This amp caters well to various music genres, making it a great choice for blues, rock, country, and jazz musicians. Its compact design and 12-watt output make it ideal for both practice sessions and small gigs.

In terms of construction, the amp is robust and well-crafted. The solid pine cabinet and vintage-style grille cloth give it a timeless look, which many appreciate. The use of high-quality components ensures durability and reliability.

Despite these strengths, some might argue that the Fender ’65 Princeton Reverb comes with fewer tweaking options compared to other amps, and the single 10″ Celestion speaker might not be to everyone’s liking. However, considering its overall value and performance, the Fender ’65 Princeton Reverb is indeed a reliable and highly-regarded amp that delivers a rich, warm tone, making it a top choice for guitarists.

The Egnater Tweaker 15W tube amp

Egnater Tweaker 15W


The Egnater Tweaker 15W is a compact, all-tube amp head that is known for its versatility and wide range of tonal options. Powered by a pair of 6V6 tubes, it deviates from the commonly used EL84 tubes in smaller amps, offering a unique sound. The front panel is filled with useful features such as toggle switches for voicing options, EQ controls, and gain settings, which give the user plenty of customizability.

Key Benefits

  • Offers a broad spectrum of tonal options from vintage to modern, and clean to high-gain
  • Powered by 6V6 tubes, providing a unique sound
  • Compact and affordable, making it suitable for home recording and small gigs
  • Features voicing switches for different styles including USA (Fender), AC (Vox), and British (Marshall)
  • Has a buffered effects loop for adding external effects
  • Provides enough power to perform with a loud band when gain and master settings are adjusted accordingly


The Egnater Tweaker 15W is recognized for offering great value. Despite its affordable price, it delivers premium features and performance that make it a competitive option in the market.

Pros & Cons

The Egnater Tweaker is one powerful little beast. Its 15W output, driven by 2 6V6 power tubes, makes it perfect for those who want tube saturation without excessive loudness. One of the features I appreciate the most is the various tone-shaping knobs and toggle switches, especially the vintage modern voicing switch that offers a looser, broken-in speaker feel in vintage mode, and a tighter, more articulate sound in modern mode.

The amp also includes voicing switches for different styles like USA (Fender), AC (Vox), and British (Marshall), giving you plenty of options to tailor your sound. The hot setting on the gain toggle brings more gain and saturation, which I’ve found particularly good for those looking for a heavier sound.

The back panel surprises with an effects loop and an impedance selector for different speaker configurations, making it quite versatile. The use of 3 12AX7 tubes for the preamp, in addition to the 2 6V6 tubes for power, adds depth to the sound, which I’ve found great for everything from blues to rock to indie tones.

The build quality of the amp is decent, but it could use some improvements. The absence of corner protectors and a heavy-duty handle is a bit disappointing. But overall, considering the wide range of tones, the versatility, and the affordability, I’d say the Egnater Tweaker 15W is a great deal for its price and a worthy contender.

The Supro Blues King 12

Supro Blues King 12


The Supro Blues King 12 is a compact, lightweight 15-watt tube combo amp that embodies the vintage tone of Supro amps. It draws inspiration from the iconic Supro Comet of the 1950s and is available in three variants: 1 watt combo with 8″ speaker, 5 watt combo with 10″ speaker, and a 15 watt with 12″ speaker.

Defined by its custom-made BK12 speaker, it mimics the old field-coil style speakers, contributing to its smaller size and lighter weight. The Blues King 12 is perfect for home use, studio recording, and small gigs due to its portability.

Key Benefits

  • Compact and lightweight design for easy transportation
  • Custom-made BK12 speaker for smaller size and lighter weight
  • Simple layout with volume, 3-band EQ, reverb, and master control
  • Offers foot-switchable boost and gain for versatility
  • Includes analog spring reverb, effects loop, and line out
  • Ideal for home use, studio recording, and small gigs


The Supro Blues King 12 is touted as an affordable combo amplifier that delivers big sound and great tone, all packed into a small package. It’s a budget-friendly option for blues and rock players seeking a combo amp with a vintage Supro amp tone.

Pros & Cons

As I delve into the pros and cons, it’s clear that the Supro Blues King 12 is an amp with a lot to offer. It’s small and lightweight, making it perfect for those needing a portable solution. I’ve found that the tone is warm and compressed, which is ideal for blues music. The reverb is lush and rich, adding ambiance to the sound. I love the versatility provided by the reverb control, allowing for a subtle or more washed-out effect.

The amp is also very responsive to different playing styles and picking articulations, which is a big plus. The gain switch and boost function add even more versatility, offering higher gain options with a fat mid-range boost. When pushed to higher settings, the amp can produce biting and fuzzy blues tones.

However, it’s not all perfect. While the volume control allows for varying degrees of crunch and breakup, it can easily push the amp into distorting when set high. The sound quality might not be as pristine at higher volumes as it is in lower levels.

In general, the Supro Blues King 12 is a great combo amp with a fantastic reverb and versatile tones, perfect for blues musicians and those seeking a warm, vintage tone.

The Blackstar HT-5R low-watt tube amp

Blackstar HT-5R


The Blackstar HT-5R is a 5-watt tube amp acclaimed for its remarkable sound quality and versatility. The amp is suitable for guitarists of all skill levels, from beginners to seasoned professionals. The compact design of the HT-5R makes it highly portable, making it an ideal choice for intimate jam sessions, recording sessions, and even studio work. Its features allow for a broad spectrum of tones and flexibility in sound shaping.

Key Benefits

  • 2-channel design with infinite shape feature
  • 2 voice switches
  • Power reduction circuit
  • In-built effects loop
  • Emulated and USB output
  • Studio-quality reverb
  • Compact and portable for easy transportation
  • Ideal for a wide range of tones and sound shaping
  • Suitable for musicians of all levels


The Blackstar HT-5R is available for purchase from various retailers. It’s known for delivering excellent value for its price, making it a popular choice among musicians on a budget. It is also available in a special edition Bronco Grey color.

Pros & Cons

From my perspective, the Blackstar HT-5R stands out for its excellent tone, flexibility, and compact design. The 12AX7 preamp tube and a 12BH7 power tube deliver a rich and dynamic sound that is truly impressive. It’s easy to dial in a great sound thanks to the simple controls on the top panel.

The amp features two channels; clean and overdrive, each with two voicing options. This adds a layer of versatility to the amp that I find particularly useful. The clean channel delivers warm and sparkling tones, but it’s the overdrive channel that really shines for me, with the ability to go from near-breakup to wild distortion.

One feature that impresses me is the built-in reverb. It adds depth and dimension to both clean and distorted sounds, enhancing the overall sound quality. The power attenuator is another useful feature, allowing you to lower the wattage to 0.5 for quieter practice sessions.

Connectivity options are also abundant on the HT-5R. The back of the amp includes speaker outputs, an effects loop, a headphone output, and a USB output for recording.

As good as it is, the Blackstar HT-5R isn’t flawless. Some users may find the lack of multiple speakers limiting. Additionally, while the amp is praised for its ability to take pedals well, it may not meet the needs of those looking for more extensive effects options.

That said, in my view, the Blackstar HT-5R is a superb amp. It offers a fantastic blend of affordability, versatility, and quality, which makes it a popular choice among guitarists of all skill levels.

What Is A Tube Amp And How Does Wattage Affect Sound?

A tube amplifier, or tube amp as it’s commonly known, uses vacuum tubes to amplify the signal from an electric guitar. Musicians love them for their warm, rich sound quality that’s been a game changer in music history across various genres. From blues and jazz to rock ‘n’ roll and heavy metal, the unique sound characteristics of tube amps have shaped the sound of these musical styles. We have looked at many features which make up the best low-watt tube amps, including: the watt tube, the cheapest tube amps, the low watt tube itself (low-wattage tube amps as a whole), which work with a guitar combo amplifier and power amp, amp heads, solid state amps, combo amps, smaller tube amps, vintage amps and more.

In a tube amp, wattage is a key player in determining its sound. The wattage of a tube amp affects the headroom it has, which in turn influences the amp’s tone and distortion levels. Higher wattage amps tend to have more headroom, meaning they can produce louder and cleaner tones. Conversely, lower wattage amps often distort at lower volume levels, resulting in a more saturated and overdriven sound.

If you’re looking for an amp for daily practice, rehearsals, or even small to medium-sized gigs, low-watt tube amps, like the ones mentioned in the references, could be your best bet. They can deliver the authentic, warm sound of larger stage equipment without becoming excessively loud. This makes low-watt tube amps perfect for home use or as a portable backup for gigs. Plus, they’re often more affordable and easier to lug around than their higher-wattage counterparts.

Tube amps with power attenuation, such as the Orange Rocker 15 and the Peavey Classic 20, are designed to keep their rich sound quality at lower volumes. This feature lets the amp run at lower wattages while still achieving overdrive and rich sound, making them perfect for practising and recording at home.

So, whether you’re considering a high or low-wattage tube amp, each has its unique sound characteristics and advantages. Your choice will largely depend on your personal preference, budget, and intended use, whether it’s for practice, recording, or performing.

The Power Of Low-Watt Tubes

Choosing the right low-watt tube amp is an essential step in shaping your unique sound as a musician. It’s important to remember that every amp is unique, offering its own potential for tone shaping – be it the vintage sound of Fender ’57 Custom Champ 5W, the iconic British tone of the Vox AC15C1 15W, the classic Marshall sound of the Marshall SV20H Studio Vintage, or the metal tones of the Mesa/Boogie Mark Five:25. We have discussed some of the best low-watt tube amps including Fender ’65 Princeton Reverb, Egnater Tweaker 15W, Supro Blues King 12, and Blackstar HT-5R.

Each of these amps brings different characteristics and is priced for various budgets, so carefully consider their pros, cons, and key benefits when making your decision. Whether you’re a seasoned professional or an aspiring beginner, the selected amp can greatly enhance your musical style and performance. Moreover, it’s a smart investment that can last you for many years of playtime, studio recordings, and live performances.

Remember, the amp that you choose should allow you to express your musicality, harmonize with your preferred genre, and accommodate your specific needs – be it home studio recording, live gigs, or simply jamming out with friends.

No matter your choice, you can trust that each of these amps has been crafted with care and precision, designed to deliver quality sound and an enjoyable playing experience. After all, the power of low-watt tubes lies in their ability to bring your music to life, allowing you to create and share your art with the world. So, go ahead and unleash your sonic potential with the best low watt tube amp that suits your style and needs. Happy playing!
