Tone Merchants NTMB Onboard Preamp

Tone Merchants NTMB Onboard Preamp came about from teaming up with Bartolini to pursue a dream of mine. To create my own drop in, onboard preamp for basses with an F style control plate. Cause that’s a bunch of stuff out there, and most have poor electronics.

All hand wired here in Auckland, New Zealand using a Bartolini NTMB-F Preamp (preamp is made in the USA). With high quality Alpha Pots, I have put together what to me is one of the most functional & musically useful preamp configurations, while staying withing the restrictions of a 4 knob layout.

If you are wanting this same preamp, but do not need the control plate and knobs. The check out my Tone Merchants NTMB Preamp, it’s exactly the same, but as a harness only.

Pre Tinned Leads For Easy Soldering

All Tone Merchants Wiring harnesses & control plates are designed to make it easy to install. Your find the “Hot Wires” that are to be connected to your pickups already soldered to the pots. So all your need to do is connect the wires of your pickups to these and then heat-shrink wrap the exposed wire (provided). This removes a lot of the effort when new to soldering and the fears around over-heating the pots. Not to mention trying to get your soldering iron past the many wires found in active, onboard preamps.
