Seymour Duncan Music Man Active 3 Knob Bass Guitar Preamp, Black

The Seymour Duncan STC-3M3 Music Man Tone Circuit is a versatile 3-knob active preamp designed to unlock a wide range of tonal control for Stingray-style basses and similar configurations. Featuring a stacked bass/treble control, dedicated midrange control, and a master volume with a push/pull Slap Switch, it delivers everything from deep, tight lows and smooth, musical mids to bright, articulate highs without harshness. The onboard Slap Switch engages a specially voiced EQ contour for punchy, modern slap tones, with internal trim pots allowing fine adjustment of the contour to suit your playing style. Designed for flexibility, it can be used in instruments with a single passive pickup and sufficient control cavity space, and even supports dual 9V wiring for increased headroom. The system includes a complete pre-wired harness with high-quality pots, stereo jack, battery clip, and black anodized dome knobs for a professional-grade installation.
