Radial Twin-City – Active ABY Guitar Amp Switcher with Isolated Outputs (R800-7115-00)

The Radial Twin-City ABY Switcher is a professional-grade, active amp selector that lets you seamlessly toggle between two guitar amps or use both simultaneously—without hum, tone loss, or signal degradation. Whether you're switching for tonal variety or running stereo amp rigs, the Twin-City ensures consistent, noise-free operation in both studio and live environments.

Built around a class-A discrete buffer and designed with tone preservation in mind, the Twin-City delivers the full character of your instrument to both amps with complete control over phase and ground loops.

Why Choose the Twin-City ABY Switcher?

The Twin-City is ideal for guitarists looking to run dual amp setups with no loss in clarity, punch, or dynamics. Unlike passive ABY boxes that can suffer from impedance mismatch or hum, Radial’s active circuit ensures clean, transparent signal routing with built-in tools to correct common issues like ground hum and phase cancellation.

Trusted by professionals worldwide, the Twin-City shares the same signal path as the legendary JD7 used by Steve Vai and Carlos Santana, delivering studio-grade performance in a compact pedal format.
