Mozztronics BB-2 Duo Boost

A 2 channel version of the BB-1 Big Boost. Same boost circuit, but with 2 footswitchable channels. There is nothing like slamming the front end of a valve amp with a booster.
 
The Mozztronics Duo Boost BB-2 can provide a massive 27dB of gain, while operating from a single 9VDC supply. We also include a switchable high input impedance input buffer, to drive long cables without tone sucking. No charge pump or switching internal power supplies here. We use class AB and quasi class G internal circuitry to provide the headroom for 27dB of clean gain. BOOST controls the amount of boost available from 0 to 27dB. CONTOUR switches between full range and a slight bass cut BYP selects whether in bypass mode, you don’t have the buffer in circuit (BYP) or so have the buffer in circuit (BYP+BUFF)
