Custom Modified Nordstrand Preamp Harness

Great guys working at Fat Bass Tone. They translated my wishes into a modified preamp with all the functionality I wanted, then actually did the modification and shipped it with crystal clear instructions.

Nordstrand 3-band is just awesome

Added 3B-4B to a set of P/J Nordstrand pickups. Not much of an electronics guy, but soldering the pickups was not hard at all. The guys at FBT answered a handful of questions about grounding too. Great service!

A significant upgrade to my custom bass for a great price. Would definitely use these guys again!

Nordstrand 3b4b

After trying several other preamps, this one stayed. It really brought my bass to life. Other preamps tend to color and truncate your passive tone. This thing lets your highs, mids and lows shine through, making my bass cut through the stage mix. It sounds so incredible. I highly recommend.

Nordstrand 3b4b

I installed this preamp along with the NJ4 pickups into my Lakland USA 44-60 Vintage Jazz bass. I love the sound. I've tried quite a few other preamps and this one stays. I wanted a transparent sound that captures the true essence of the bass and doesn't compress it. This is it! When boosting or cutting, the sound is very pleasing at any combination compared to other preamps. I've never really tweaked much on other preamps, but this one really responds. I wish I've tried this Nordstrand combo sooner. I highly recommend this for higher end basses where you don't want to color a great bass tone.
