Seymour Duncan STC-2ASB 2-Band Preamp for Active Pickups

Control Configuration

Volume/Slap Switch Push/Pull
Blend
Treble/Bass Stack

High headroom, low-noise, 2-Band active onboard EQ preamp voiced specifically for fretless basses with active pickups.

Seymour Duncan Tone Circuits will add a tremendous amount of on-board tonal versatility to any dual pickup bass. Our design enables players to boost or cut specifically focused frequencies in order to achieve signature tones and to dial in a great sound no matter what the situation. We even added the two small trim pots on the circuit board can be tweaked to preset the frequency contour EQ just the way you want.

The STC-2ASB Tone Circuit provides bass and treble controls, a master volume, a blend control, and our special frequency contour switch. This preamp was voiced by Steve Bailey to have two bands of focused EQ, together with a switch that engages a frequency contour optimized to bring out fretless harmonics as well as mid-range boost. The frequency contour is engaged by pulling up of the volume control.

The STC-2ASB will work in any fretless bass that is equipped with two active pickups and has space for 3 control knobs (volumefreq switch, blend, concentric bass and treble controls) and a single 9v battery in the control cavity. Two 9v batteries can be wired together in series for added headroom.
