Huge Audio Router AB Loop

The AB LOOP model is a completely passive router and therefore completely transparent. It is the combination of the AB and LOOP models in the same box. Two LEDs supplied by battery or by 9V transformer indicate which output of A or B is selected. A third indicates whether the effects loop is engaged. As with all Huge Audio routers, the power supply is only switched on when there is an input jack. In addition, in the absence of an input jack, the sound is electrically mutated on all the amps. Absolutely no sound comes out even at maximum volume! Made in Germany.
