The Only Amp Switcher You Need

The Radial Twin-City is an active ABY amp switcher that lets you connect any two guitar amps and switch between them or drive them both simultaneously, without noise, signal loss, or any degradation to your natural guitar tone. Whether you're blending a clean amp with a dirty one, running stereo rigs, or just want the flexibility of two sounds at your feet, the Twin-City handles it cleanly and quietly.

Class-A Buffer and Drag Control

At the heart of the Twin-City is a Class-A input buffer that drives both amp outputs, lowering impedance and reducing susceptibility to noise allowing for completely silent switching on stage. Radial's Drag Control load correction lets you dial in the natural interaction between your guitar pickups and a tube amplifier, compensating for the way buffered signals can feel different to plugging straight into an amp. The Drag Control recreates the natural load on the pickups as if your guitar was connected directly to the tube amp.

Noise-Free Switching

To eliminate hum and buzz from ground loops, the Twin-City features an isolation transformer on output B, a ground lift switch, and a 180-degree polarity reverse switch that ensures both amplifiers play back in phase with each other.
