Description
The Radial Twin City solves the classic problem of running two amps live: how to switch cleanly without a pop, hum, or dropout. Its class-A input buffer drives both amp outputs directly, keeping noise low and making switches between amps completely silent on stage — no thumps, no dropouts to distract from the performance.
- Isolation transformer on output B breaks ground loops that would otherwise cause hum and buzz when two amps share a stage or power circuit.
- Ground lift switch gives you a second option for chasing down noise issues.
- 180° polarity reverse switch keeps both amps in phase with each other, so combined tone stays full instead of thinning out from cancellation.
- Drag Control load correction at the input recreates the resistive load your pickups would feel plugged straight into a tube amp, so your guitar’s natural tone and dynamics come through untouched even after splitting the signal.
Built for guitarists who run wet/dry rigs, dual-amp setups, or simply want the flexibility to A/B between two amps mid-set. The Twin City handles the switching duties quietly so you can focus on the music, not the gear.
