The Seymour Duncan STC-3A Active Bass Preamp features a three-band active on-board EQ, a pre-wired four-knob harness and offers high headroom. This Tone Circuits will add on-board tonal versatility to any dual pickup bass with a design that 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. Two small trim pots have been added on the circuit board and can be tweaked to preset the frequency contour EQ.
The STC-3A Tone Circuit provides a four-knob prewired harness that includes a stacked basstreble control, a midrange control, a master volume, a blend control, and the Slap Switch. The treble control can produce a wide ranging, extremely usable response that is brilliant, yet smooth without being brittle. The midrange control can be used to just slightly remove excess midrange honk or to add sonic power. The bass can be reduced to tighten up a boomy instrument, or it can be increased to add warmth and punch.
