The Radial Engineering Twin-City aby pedal

Radial Engineering Twin-City


As guitar enthusiasts ourselves, we can attest to the value of the Radial Engineering Twin-City. This active amp selector is designed with guitarists in mind, providing a seamless connection of two guitar amps. It enables switching between them or using them simultaneously, and the best part? There’s no noise or loss of gain. Constructed from durable 14-gauge steel, the Twin-City can be powered with a standard 9V power supply, making it a sturdy and practical addition to any guitarist’s gear.

Key Benefits

The Twin-City stands out for its various features, giving it multiple benefits:

  • It is an ideal tool for combining two guitar amps, using it as a channel switcher, or even with two bass amps.
  • Reliability and versatility are at its core, providing a practical solution for guitarists who want to switch between amps or use multiple amps at the same time without any signal degradation.
  • It maintains the integrity of the guitar tone, giving you a noise-free performance that is applauded by many guitarists.


Judging by its rich features and the high quality it offers, we believe it represents a valuable investment for serious guitarists.

Pros & Cons

As with any product, the Twin-City has its strengths and weaknesses. On the positive side, it uses a class-A input buffer to drive the amp outputs, which significantly reduces susceptibility to noise and ensures silent switching on stage. It’s also equipped with an isolation transformer on output-B to eliminate any annoying hum or buzz from ground loops.

Furthermore, the Twin-City features a ground lift switch and a 180⁰ polarity reverse switch to ensure both amplifiers play back in phase with each other. This feature alone is a game-changer for many guitarists. Lastly, the Drag Control load correction feature allows you to recreate the natural load on the pickups, preserving the natural tone of your instrument.

However, we feel it’s important to mention the lack of clear pricing information as a minor drawback. Despite this, we believe that the pros far outweigh the cons, making the Twin-City a valuable tool for any guitarist, regardless of their skill level or style.

What Is an ABY Pedal?

An ABY pedal is a specialized device that provides guitarists with the flexibility to integrate two amplifiers into their setup. This allows musicians to switch between the amplifiers or use both simultaneously, depending on the desired sound. ABY pedals are often used by guitarists who want to alternate between different amplifiers for clean and distorted tones, or even create a stereo amp rig for a richer sound experience.

A key definition to remember about ABY pedals is their categorization into either passive or active types. Passive ABY pedals are simple switches that divert the guitar signal to one amplifier or the other without requiring power. On the other hand, active ABY pedals require power and employ a buffer or unity-gain amplifier to reduce noise and manage the electrical signal more effectively.

Another significant distinction between different ABY guitar pedals lies in their switching mechanism. Some use true bypass switching to maintain the integrity of the signal, while others feature buffered circuits to prevent signal degradation. This becomes particularly important if a musician uses extensive cable runs in their signal chain, where buffered pedals can ensure a strong signal throughout.

Furthermore, some ABY pedals feature a polarity reversal switch to avoid phase cancellation when using two amps. Phase cancellation can occur when similar frequencies from separate sound sources are played together, resulting in a flat and thin sound. This functionality greatly enhances the quality of the output, making it a desired feature in many ABY pedals.

ABY pedals come in a variety of designs, sizes, and price ranges, each providing unique features and benefits. They are a versatile addition to any guitarist’s equipment, providing a range of tonal options and enhancing the overall musical experience.

When To Use An ABY Pedal

As a guitarist, you may find yourself in need of more tonal options, or perhaps you require a seamless way to switch between different amplifiers. This is where an ABY pedal can be a game-changer. It’s an invaluable tool for integrating two amplifiers into your setup, allowing you to switch between them smoothly or use both simultaneously for a broader, richer sound experience.

ABY pedals are particularly useful when you want to use different amplifiers for producing distinct tones – clean and distorted, for example. The ability to alternate between these tones can significantly enhance your musical performance, providing a depth and variety that a single amplifier might not deliver.

Constructing a stereo amp rig is another scenario where an ABY pedal comes in handy. You can position two amplifiers at opposite ends of the stage, creating a three-dimensional sonic experience. This not only enriches the sound but also allows you to use stereo effects, adding another layer of versatility to your performance.

Furthermore, if your signal chain involves extensive cable runs, a buffered ABY pedal can ensure that the signal remains strong throughout, preventing any loss of tone. Conversely, if you prefer a simple switch to divert the guitar signal to one amplifier or the other, a passive ABY pedal would be the best choice.

However, it’s crucial to remember that the right ABY pedal for you depends on your unique needs and preferences. Examining your musical setup and requirements will help you choose the ABY pedal that will provide the most benefits. Whether it’s for switching between amps, creating a stereo rig, or combining signals, there’s an ABY pedal out there that can meet your specific needs and enhance your guitar-playing experience.

Amping Up Your Guitar’s Performance: The Final Note

Our exploration of ABY pedals has given us a deep understanding of their versatility and value. While there are various models with different features and price points, they all carry a common thread of enhancing your guitar’s performance by integrating two amplifiers into your setup. Whether you’re using different amplifiers for distinct tones, constructing a stereo amp rig, or simply want a seamless way to switch between your amps, an ABY pedal can be a game-changer for your sound setup.

We have seen the importance of factors such as active vs passive types, the switching mechanism, and the ability to handle phase cancellation. Prices can vary, but the investment can certainly enhance your musical efficiency, creativity, and overall experience.

In conclusion, we’d say that the right ABY pedal will truly depend on your individual needs, preferences, and the specifics of your setup. As a guitarist, investing in an ABY pedal could amplify your art, literally and figuratively. So, whether you’re an amateur, a pro, or somewhere in between, an ABY pedal might just be the tool to enhance your musical journey, one switch at a time!

Remember, the best musicians know their gear as well as they know their music. Keep experimenting, keep exploring, and let your ABY pedal guide you towards uncharted sonic territories.
