On Stage A/B Box Effect Pedal

No sales tax for customers outside California.  

The On-Stage A/B Box Effect Pedal is a simple and reliable signal-routing tool designed for guitarists, bassists, and multi-instrumentalists who need to switch between two outputs or inputs with ease. Whether you're toggling between two amplifiers, switching instruments into a single rig, or routing signals onstage or in the studio, this A/B box delivers quiet, pop-free switching and durable construction. 

$50.95 new from other retailers.

Switch between two amps or use both - a switchable option.

Built into a rugged metal housing, it features a single footswitch, input jack, and two selectable outputs (A and B), along with status indicator LEDs. This unit works with passive or active instruments and requires only a standard 9V power source for LED illumination—signal routing functions even without power.

This example is in excellent condition and functions perfectly, showing minimal cosmetic wear.
