Designed as a single input / three output (switchable) active audio distribution preamp, the Kendrick ABC box can be used for multi-amp setups, amp switching, or channel switching. Any one of the footswitchable outputs can be a "send" for a tuner or for studio use. The input and all outputs are isolated and buffered. Heavy duty switches are arranged in a unique triangular configuration allowing all three, any two, or any one output to be switched with a single foot-step. Zero insertion loss and unity gain, all three output signals are identical to the input signal. LED status indicators. 120VAC.

"Our first pedal was the Kendrick ABC Box, which was built as a one-off for the company president so that he could use a three-amp setup without impedance loading and switch amps off and on during performances. Some of Kendrick's 17 employees and their friends wanted one for themselves, so we made a run of 100 of them which quickly sold out. They were so popular that we continued to make them and still do to this day. Besides switching amps on or off, they can be used for a variety of other purposes in live performances, such as "ping pong" echo, multiple sends for recording, dedicated send for tuners, etc"
