Possibly the World's cleanest, most transparent boost. It utilizes the 7660S charge pump's ability to take a standard 9v power supply and output both +18v and -9v. The op-amp based boost circuit takes advantage of the whopping 27v differential to produce 20dB with an amazing amount of headroom. It doesn't matter if you're using active pickups - you will not get any clipping from this boost. Slam it with another boost, it still won't clip! The treble control allows you to cut/boost frequencies above 3k3Hz by 6dB.

Features all through-hole components ad full-size panel mounted hardware.
