The Radial Bones Twin-City ABY amp switcher lets you connect to two amps simultaneously — and run them both with no extra noise or signal loss! The Bones Twin-City includes both an ABY switcher and a buffer as well as Radial's Drag Control load correction circuitry, which lets you eliminate signal loss. This amazing box includes a pedal that lets you toggle between amps as well as a pedal to select both outputs. It also includes an isolation transformer, to eliminate hum and buzz from ground loops. Get the most out of your 2-amp setup, with the Bones Twin-City!

Essential for your 2-amp setup
The Twin-City enables you to connect any two amps and drive them simultaneously without noise, loss of gain and without degrading your natural guitar tone. This is accomplished with Radial's highly acclaimed buffering technology and the same Drag Control (TM) load correction circuitry as used in the award-winning Radial JD7 Injector. The set-and-forget Drag Control lets you compensate for cable signal loss and introduce the perfect amount of loading to replicate the way your guitar and amp interact.

Eliminate hums and buzzes
To eliminate hum and buzz from ground loops, the Twin-City is equipped with an isolation transformer on output B. This is augmented with a ground lift switch and 180-degree polarity reverse switch that ensures both amplifiers play in phase while noise is reduced to an absolute minimum even when using older vintage amps, which are generally more prone to noise. As a buffer, the Twin-City lowers the impedance and susceptibility to noise, making it the ideal signal driver for large stages when using long cable runs.

Take it on the road
Like all Radial products, the Bones are constructed from heavy 14 gauge steel for road-ready reliability. For even greater durability, the Twin-City employs Radial's Electronic Impulse Switching. EIS gives Bones pedals unmatched performance, without the challenges posed by mechanical switches. Bright, easy to see LEDs deliver on-stage switching cues so you know exactly where you are at all times.
