The STC-3M3 is the 3-knob version of our Music Man Tone Circuit, and has a stacked 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 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.Combine with our Music Man replacement pickups for a complete setup.The STC-3M3 is specifically designed for Stingray basses, but will also work in any bass that is equipped with one passive pickup and has space for 3 control knobs (volumeslap switch, midrange, concentric basstreble control) and a single 9v battery in the control cavity.

Two 9v batteries can be wired together in series for added headroom.

Use together with replacement pickup for Music Man bass.

For Music Man® StingRay® basses and other basses with a single passive pickup. Will not work with 3-coil pickup.
