Radial Bigshot ABY True-Bypass Amp Switcher V2

The Radial BigShot ABY V2 is a passive true-bypass switcher that routes your signal to either of two amps or both at once. Two latching footswitches handle A/B selection or simultaneous use, while a dedicated always-on tuner output keeps monitoring separate from the main signal path. Output B includes a switchable isolation transformer, ground lift, and 180-¦ polarity reverse to address ground loops and phase issues when running dual amps. The circuit stays fully passive for tone transparency even without power. LEDs light up for visual status only when a 9VDC supply is connected; the audio path functions regardless. Specifications
