Frequently asked questions
Will the STC-3M4 fit my non-Music Man bass?
The STC-3M4 is engineered specifically for Music Man instruments with four-knob control cavities. The STC-3P is the universal option for other bass designs with two pickups and four control knobs.
What is the Slap Switch and how does it differ between these two?
Both circuits include a proprietary Slap Switch for enhanced percussive texture. The STC-3P uses a dedicated physical switch, while the STC-3M4 integrates it as a push/pull function on the master volume knob. The STC-3M4 also includes trim potentiometers to preset your slap contour EQ.
Can I run either preamp on two 9v batteries?
Yes, both the STC-3P and STC-3M4 support single 9v battery operation with the option to wire two batteries in series for increased headroom and dynamic range.
Does the STC-3P have a blend control that the STC-3M4 lacks?
Yes, the STC-3P includes a dedicated blend control for adjusting the balance between two pickups. The STC-3M4 does not feature a blend control and focuses on master volume, bass, treble, and midrange adjustment only.
