Bartolini

HR‐3.3AP/918

Bartolini 2 Band Bass Preamps

The NTBT is a 2-band tone control preamp with fully independent Bass and Treble controls.

  • The voice is clear, transparent, and strong with wide boost and cut range for aggressive control. The NTMB features an adjustable gain which allows you to boost the input signal up to 12dB while maintaining flat frequency response.

    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. 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. Bartolini uses only professional lead-free solder with non-corrosive flux.

    A stacked knob is included with harnesses which have a stacked pot. 

    Artists: David Wilson
