Radial Engineering Switchbone V2 Amp Switcher and Booster

The Switchbone V2 may well be the ultimate guitar amp switcher. This device lets you switch and combine up to three guitar amplifiers without introducing distortion, switching noise, or hum into the signal path. Most importantly, it will retain the natural tone and feel of your instrument so that your natural playing style shines through. The Switchbone V2 may be used as a standard ABY switcher with both A and B outputs used separately or together, or the tuner output can be repurposed to feed a third amplifier. A built-in power booster at the output delivers up to +18db of ultra-clean boost with the option to add mid-boost for extra sustain when playing lead.

Standard ABY setup

The Switchbone is a high performance ABY designed to deliver the natural tone of your instrument to your amps without introducing noise or artefact.


Used as an ABC amp selector

Use the tuner/out-C as a third output to select between three different amps. Transformer isolation and buffered outputs eliminate ground loops and noise.


Used as a channel selector

For older amps, the Switchbone can be used to drive the two amp channels so that you can toggle between them. Use the Slingshot output to control amp settings like reverb.
