This active EQ system for bass guitar features three bands with independent boost/cut for Mid, Bass, and Treble via two stack pots. It features a center detent. The Mid control has a variable frequency knob with a selectable range of 100Hz-1KHz. It works with both active and passive pickups.
This control system is ideal for active bass pickups and includes a master volume, balancer, and 2-band EQ with a center detent. Dual dip switches on the PC board allow you to select from four treble curve patterns.
The 3-band EQ system is compatible with both passive and active pickups. The active circuitry allows for boosting the treble, while the passive circuitry allows for cut, creating a vintage tone.
