DESCRIPTION

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 concentric knob set is included with harnesses which have a stacked pot. Bartolini does not include any other knobs with their preamps.

Always have a great experience buying from FBT

I've had a great experience with both of my purchases. Max is very knowledgeable and takes the time to explain everything well, and helping you make the best selection. All purchased items have arrived quickly and without any issues. I did some research before choosing an online store to buy my bass upgrades, I am happy I choose Fat Bass Tone. You guys rock!!!

Lovely experience

The contact I had with the guys at Fat Bass Tone, due to my purchase I made from them was great - really nice guys and an asset to the bass community. It was obvious that they were really committed to me getting what I needed, and that they cared about me being satisfied with the result. Which I was! :-)

Great tone!

Excellent product, did exactly what I needed and sounds fantastic. Would have been better with some longer wires, though, since the ones attaching the pots to the module weren't long enough to reach the battery compartment in my Bacchus. I had to cut them and solder in some extensions. Other than that, no complaints!

Thanks for your comments, Kevin. Glad the preamp sounds good! Bartolini pre-wires these preamps at their factory - We will pass on your thoughts about the wire length.
