Complete with true bypass circuitry, heavy-duty black anodized aluminum housing and slip-resistant rubber base, the On-Stage GSP1000 ABY Switcher gives musicians the ultimate choice between 2 input/1 output and/or 1 input/2 output configurations. Run one signal to two separate amps for real-time stereo, pivot to and from two amps for dirty/clean dynamics, run two separate instruments through your effects chain simultaneously or bypass anything from that temperamental boutique effect to your entire pedal board. The possibilities are myriad; the quality assured and the choices yours.
