Seymour Duncan STC-3P Bass Pre Amp

The Seymour Duncan STC-3P, designed for passive pickups, provides concentric bass and treble controls, mid range control, a master volume, a blend control and a Slap Switch. The treble control can produce a wide ranging, extremely usable response that is brilliant, yet smooth without being brittle. The bass can be reduced to tighten up a boomy instrument, or it can be increased to add warmth and punch. Mid range can adjust to give more punch or scoop for more clarity. The two small trim pots on the circuit board can be tweaked to preset the slap contour EQ just the way you want.
