Category: Bass Preamp Circuits
Onboard preamp circuits give you active EQ control right at the bass, letting you shape mids and boost output without reaching for a pedal. Useful for players who want stage-ready flexibility built into the instrument itself, though installation usually means routing a cavity and wiring a battery compartment. Check voltage and control layout against your current setup before swapping one in.
