Frequently asked questions
Which one requires batteries?
The STC-2PSB is passive and requires no battery. The STC-3M3 is active and requires a battery for operation.
Can I use the STC-3M3 on a fretless bass?
While the STC-3M3 can technically be installed in compatible basses, it is not designed or optimized for fretless. The STC-2PSB includes a fretless-specific harmonic-enhancement switch that the STC-3M3 lacks.
Which is better for a beginner?
Both require intermediate to advanced installation skills. The STC-3M3 is slightly more beginner-friendly because it arrives pre-wired and drops in with minimal soldering, whereas the STC-2PSB is a component circuit requiring more integration work.
What is the key tonal difference?
The STC-2PSB emphasizes warm, harmonic-rich tones ideal for fretless expression. The STC-3M3 prioritizes surgical midrange control and low-noise active shaping for precise studio and live tone sculpting.
