Frequently asked questions

Which one fits my Music Man Stingray?

The STC-3M3 is engineered and pre-wired for Music Man Stingray upgrades. The STC-3P is designed for any passive bass with two pickups and standard cavities, so compatibility depends on your Stingray's exact configuration and wiring space.

Do both have a Slap Switch?

Yes. The STC-3P includes a dedicated proprietary Slap Switch. The STC-3M3 integrates a push/pull Slap Switch into the master volume knob, plus two hidden trim pots on the circuit board for advanced slap contour shaping.

Which preamp has more hands-on control?

The STC-3P offers five physical controls (concentric bass/treble, mid, master volume, blend, Slap Switch), giving you immediate access to all functions. The STC-3M3 has three knobs plus two hidden trim pots; it's cleaner visually but requires soldering adjustment for fine slap EQ tuning.

Can I use either in any bass?

The STC-3P is designed for any two-pickup passive bass with space for four control knobs and a 9v battery cavity. The STC-3M3 is optimized for Music Man Stingray or single-pickup passive basses; universal fit depends on your cavity layout and wiring needs.
