Frequently asked questions
Which one fits Music Man Stingray basses?
The STC-3M3 is engineered specifically for Music Man Stingray upgrades and arrives pre-wired for direct installation. The STC-2ASB is a general-purpose active preamp not optimized for any specific instrument model.
How many bands of EQ control does each offer?
The STC-2ASB provides 2 bands (bass and treble) with preset frequency voicings selectable via the pull-up contour switch. The STC-3M3 provides 3 independent bands (bass, midrange, treble) for more granular tonal shaping.
Which requires more installation work?
The STC-3M3 comes pre-wired with all hardware included, requiring minimal soldering. The STC-2ASB requires manual wiring of components into your bass's control cavity, making it better suited for experienced builders.
What is the frequency contour switch on the STC-2ASB?
It is a toggle switch accessed by pulling up the volume knob that switches between preset EQ voicings without adding external hardware. Two trim pots on the circuit board let you customize which frequencies those presets target.
