Bartolini HR-3.4/918FL Pre-Wired Harness

Bartolini HR-3.4/918FL Pre-Wired Harness

The NTMB+FL is well known to professionals for its very low noise and precise control. It is a 3-band tone control preamp with fully independent Bass, Mid and Treble controls. The adjustment range is refined for precise control. Often used in fretless instruments for more focused mid control, the FL voice is the same as the original Bartolini TMB from the 1980s.

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 our pro-level preamp and premium audio-quality pots and switches, you’ll have smooth control and be ready for years of rugged use. We include 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. We 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, we include a ring knob and center knob since they are not as common.
