BOSS AB-2 2-Way A/B Selector Pedal

BOSS AB-2 2-Way A/B Selector Pedal

The BOSS AB-2 2-Way A/B Selector Pedal provides silent, one-stomp switching between two signal paths. Its reversible design can route one guitar to two amplifiers or accept two guitars into one effects or amplifier chain, making it a compact solution for instrument selection, amp switching, effects routing, and tuner muting.

Players can use the AB-2 to move between clean and lead amplifiers, change instruments without repatching cables, select alternate effects setups, or create a tuning-mute path between an amplifier and tuner. Red and yellow indicators clearly identify the active A or B channel, while the single pedal control keeps operation straightforward during performances and rehearsals.

The BOSS AB-2 uses three signal connections labeled A, B, and IN/OUT, allowing the same pedal to function as either an input or output selector. Two AAA batteries power the switching circuit for approximately 100 hours with carbon batteries under continuous-use conditions. It is designed for instrument and effects-level signals and should not be used to switch power-amplifier speaker outputs.
