B85 Audio
Bass Preamp
The B85 audio Bass Preamp is a floor MOSFET preamplifier for bass guitar, it has a classic Treble control for setting high frequencies, Middle for setting center frequencies, Bass for setting low frequencies, Volume for setting volume, Gain for setting preamplification and two two-position ACT/PAS switches for setting passive or active basses and HI/LO for setting frequencies. The preamp is built on a TLC2272 chip, so the effect is very quiet and clean. The whole effect is hand-made, and this also applies to the printed circuit board.
