Frequently asked questions
Which is better for fretless bass?
The STC-2PSB is specifically optimized for fretless harmonics with preset EQ tuning designed to enhance fretless character while maintaining passive responsiveness. The STC-3M3 offers no fretless-specific tuning and is designed primarily for single-pickup Stingray basses.
Can I use either circuit in any bass?
The STC-2PSB works with any passive pickup system requiring standard control cavity space for three knobs. The STC-3M3 is engineered for Music Man Stingray upgrades and compatible single-pickup basses; verify compatibility with your specific instrument before purchasing.
What is the key difference in EQ capability?
The STC-2PSB provides 2-band EQ (bass and treble) with focus on midrange and harmonic boost. The STC-3M3 provides 3-band active EQ with independent control of bass, midrange, and treble, offering more granular frequency shaping.
Which requires more installation experience?
Both are pre-wired and designed for intermediate to advanced users. The STC-2PSB requires basic cavity space; the STC-3M3 may require verification of compatibility and stereo jack installation specific to Stingray electronics.
