AB-2 Foot Switch

The BOSS AB-2 is a small 2-way selector that makes changing inputs or outputs easy. It's got 3 connections labelled in/out, A and B. In the first position in/out is connected to A. Click the switch and in/out is connected to B. The AB-2 can be used to switch between 2 guitars using one amplifier, or it can be used with one guitar, switching between 2 amplifiers.

The switching circuit is electronic and powered by a AAA battery. There's also 2 LEDs indicating if the input/output is switched to A or B. The chassis is metal and should last as long as Boss pedals normally do.
