The MIDDLE BOOSTER or „West Coast Boost“ was manufactured as a 9V battery powered floor-pedal or as on-board electronics with an idea in mind to make the guitar overall tone fatter or more jazzy-like without adding any distortion. It is a clean booster with one (midrange) gain control (+12dB) especially effective on single-coil guitars to actively increase the full-bodied sound on 3 upper strings and ease the soloing and sustain without changing the original ton-timbre. Limited edition made only for VIPs. NOT IN SALES.
