Description
If your fretted bass needs real tonal control rather than a vague “more/less EQ” knob, the Bartolini NTMB+ GF delivers three genuinely independent bands — Bass, Mid, and Treble — each with a wide boost/cut sweep so you can sculpt your sound instead of fighting it. Everything lives on a single compact module, which makes installation straightforward whether you’re upgrading an existing preamp cavity or building out a new wiring harness from scratch.
Sonically, this is about as transparent as active electronics get: distortion sits well under 0.001%, and a built-in gain trim lets you match output levels precisely to your pickups without introducing hiss or coloration. That clarity carries through whether you run it on 9 volts or step up to 18-volt operation, which frees up an extra 6 dB of headroom for players who dig in hard or run hot pickups.
Power draw is refreshingly practical for a working musician’s electronics box:
- 9V mode: ~750 microamperes — good for roughly a month of continuous use, or 6+ months of typical gigging/practice draw
- 18V mode: ~1000 microamperes — roughly 3+ weeks continuous, or 4+ months under average use
Previously sold under the part number NTMB 9183 GF, this is the same trusted circuit, now branded as the NTMB+ GF. A solid pick for anyone rebuilding electronics on a fretted bass and wanting studio-grade EQ control without the noise floor creeping up on them.
