Seymour Duncan SMB-4DS 4-String Music Man Bass Pickup with STC-3M3

The Music Man Tone Circuit, and has a stacked (or separate) bass/treble control, a midrange control, a master volume with a push-pull for our proprietary Slap Switch. The treble control can produce a wide-ranging, extremely usable response that is brilliant, yet smooth without being brittle. The lows are deep, clear, and tight. The mids range from ultra-smooth to punchy and all points in between. The Slap Switch is a push-pull 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. Combine with our Music Man replacement pickups for a complete setup. Specifically designed for Stingray basses, but will also work in any bass that is equipped with one passive pickup and has space for 3 or 4 control knobs and a single 9v battery in the control cavity. Two 9v batteries can be wired together in series for added headroom. We include all necessary mounting hardware high-quality potentiometers on pre-wired harness; battery clip; stereo jack; and black anodized, knurled, dome-style knobs. NOTE this preamp is designed for use with a standard 2-coil Music Man style pickup, and will NOT work properly if combined with a 3-coil Sterling style pickup.
