Xotic makes some of the greatest effects on the market, and this AC Booster is an early example from this fine company. #350 stamped on the back plate and opening it up reveals the first generation thru hole pcb complete with all the secrets of components and their values gooped to keep the world guessing at it's greatness. The original stomp switch has been replaced with an Alpha 3PDT, and the old part will be included. 

Full bodied boost without the TS mid hump that can stay (almost) clean or step into overdriven grind. Massive output for pushing your amp over the edge or dial in the perfect always on tone with the 2 band EQ.

Excellent condition in function and form, free shipping!
