STC-3M4 Music Man 3-band EQ, 4 knobs
These Tone Circuit preamps will squeeze out every drop of tone your bass is capable of yielding. The lows are deep, clear, and tight. The mids range from ultra-smooth to punchy and all points in between. The treble control can produce a very wide, very usable response that is brilliant, yet smooth without any brittleness. Pulling up on the volume knob activates the Slap Switch, a special EQ contour made just for slap-style playing.
