"Controls:Treble/Bass StackHigh headroom, low-noise, 2-Band active onboard EQ preamp designed for use with active pickups. Comes with prewired 3-knob harness.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.The STC-2A provides bass and treble controls, a master volume, a blend control, and our proprietary 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. The Slap Switch is a pushpull located on the volume control. Pulling up on the volume knob will engage the special EQ contour voiced specifically for slap playing. The two small trim pots on the circuit board can be tweaked to preset the slap contour EQ just the way you want.The STC-2A Tone Control is voiced to work in any bass that is equipped with two active pickups and has space for 3 control knobs (volumeslap 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.Package IncludesIncludes all necessary mounting hardwareHigh-quality potentiometers on pre-wired harnessBattery ClipStereo JackBlack Anodized, knurled, dome-style knobs."^^<http://www.w3.org/2001/XMLSchema#string>
