The Radial Headlight™ is a compact guitar amp selector that allows up to 4 amplifiers to be selected using a single footswitch. Depending on how many amps are connected, the SELECTOR footswitch will rotate through the outputs and advance them one amp at a time. A series of high-visibility LED indicators follow the active output to provide instant visual feedback on stage. Outputs 2, 3, and 4 are transformer isolated to eliminate hum and buzz caused by ground loops. These outputs are further augmented with individual ground lift switches to reduce noise and a 180º polarity reverse switch to phase-align all of the amps. A MUTE footswitch turns off all of the outputs for quiet on-stage tuning. This can also be set so that when depressed, all four amps are turned on at once. As with all Radial products, the headlight is made from 14-gauge steel for maximum durability and shielding against stray magnetic fields. Powering is done using a standard 9V supply with a typical pedalboard power brick.
