CopperSound Active ABY

A Modern ABY: The "Plug-and-Play" Solution to Control Two Paths

In the guitar world, the ABY is an essential tool whenever you want to switch from one amp to another or combine two sounds in parallel. The Coppersound Active ABY follows this tradition with an approach focused on reliability and signal quality: here, the split is not only practical but also designed to remain clean and consistent, even when your rig becomes complex. Its strength lies in its active architecture and JFET buffers, a combination appreciated for preserving the instrument's character while securing the signal path.

Who and in What Contexts to Use the Active ABY?

This pedal is intended both for gigging guitarists and studio musicians who want to streamline their routing. It is ideal if you play through two amps (clean + crunch, or combo + stack), if you build a stereo sound from two amp inputs, or if you want to drive two distinct effects chains (for example: a dry path and a heavily processed path). It is perfectly suited for styles where layering textures is essential (rock, pop, indie, post-rock, ambient), but also for more direct contexts where a clean and immediate switching on stage is needed.

On a pedalboard, the Active ABY also becomes an excellent "hub": you keep clear control over your paths while avoiding the unwanted effects typical of passive splits (perceived high-frequency loss, signal compression sensation, less crisp response under the fingers).

Controls, Design, and Key Points

The Coppersound Active ABY adopts a simple philosophy: do exactly what is expected from an ABY, but better. The core of the system relies on two independent JFET buffers that maintain a low impedance to ensure stable transmission to both outputs. In practice, this helps keep an articulated signal and more precise playing, especially when using longer cables, several true bypass pedals in series, or amp inputs with different sensitivities.

In terms of use, everything is designed for speed: the footswitch washers are the same color as the jack sockets, reducing errors live (or in rehearsal) when you need to act in a split second. The result: clear routing, immediate visual logic, and comfortable control even on a dense pedalboard.

Sound

An ABY should not impose "a sound," but it can clearly influence playing feel if the signal degrades. Here, the active approach and JFET buffers aim for a clean and faithful rendering, with a more consistent response from one output to the other. Expect better high-end retention and more stable dynamics than with a passive split, especially when combining two amps or two paths with unequal cable lengths and input loads. The feel remains direct, with a signal that better preserves attack precision and overall balance.
