5 Pots: (Volume, Blend, Treble, Push-Pull Mid, Bass) > HR-5.2/918 - Active or HR-5.2AP/918 - Active/Passive

Bartolini's most popular preamp for decades, the NTMB+F is a 3-band tone control preamp with fully independent Bass, Mid and Treble controls. It is well known to professionals for its very low noise and wide boost and cut range for aggressive control. The voice is clear, transparent, and strong. The treble frequency is set high for maximum available brightness.

A professionally pre-wired and fully pre-tested harness saves the time and aggravation of wiring your preamp and pots into your instrument. Wired with their pro-level preamp and premium audio-quality pots and switches, you’ll have smooth control and be ready for years of rugged use. Bartolini includes battery clips and an output jack for quick installation. All the pots are grounded with a wire that can be connected to the cavity shield or simply cut away if not needed in your installation. Everything is pre-soldered with pro-quality pure copper wire that is double tin-plated and protected with semi-rigid insulation so it won’t flop around in the cavity or degrade over time. They're  use only professional lead-free solder with non-corrosive flux. Knobs are a personal choice, so they are not included with the harness — except where there is a stacked (concentric) pot, they include a ring knob and center knob since they are not as common.
