The BEE pre is a versatile three-band active EQ system designed for bass guitars. The bass, midrange, and treble controls allow for +/-18dB boost and cut for each band. Potentiometers set to the center detent positions provide 3dB of overall gain through a separate op-amp circuit providing a very active touch. At the center detent positions, the preamp provides a flat frequency response from 20Hz to 16kHz.
Each unit is built with the highest quality components available and hand assembled in the USA. Each EQ is pre-tested to assure it meets or exceeds all design specifications.
