The On-Stage GSP1000 is a versatile, compact ABY switcher designed for various signal routing applications. It features a bi-directional circuit that allows for two-input/one-output or one-input/two-output configurations, making it ideal for switching between two instruments or toggling between two amplifiers. The pedal utilizes a true-bypass circuit to ensure signal integrity when the effect is disengaged, and it includes a three-color LED indicator to visually represent A, B, or A+B (both) selections. Housed in a heavy-duty aluminum chassis with a non-slip rubber base, it is built for durability on pedalboards where space is at a premium. The passive nature of the switching means it can function without power, though power is required for the LED status indicators.
