Features: Mini-Toggle 1: Vintage: for old-style Fd2 mid-heavy tones that cut through the mix. FM: stands for Flat-Mids offering a more natural sound but enhanced for even more transparency. It sounds great on a strat's Neck Pickup, truly spectacular! CompCut: removes the bounding from the feedback loop allowing for Monster Clean Boost tones and some rougher OD sounds with the OD and Boost knobs turned up. Mini-Toggle 2: MOSFET Clipping Normal Clipping:even more asymmetrical, sweeter, more open, no "blanket" over the sound. Packing Including: 1xCaline CP-20 Crazy Cacti Overdrive Pedal
