DESCRIPTION

Sonically spotless, original, and easy to use, Nordstrand's 3-Band preamp module provides players with an uninhibited musicality derived from Carey Nordstrand’s own personal design. With an ideal feature set facilitating its great sound, this module has become popular with high end bass builders who love to install them as standard OEM preamps on their top level instruments.

These preamps have become extremely popular upgrades for basses at all levels of quality. Just pick the configuration that matches the control layout on your bass!

Harnesses are professionally wired in the Fat Bass Tone shop.

All of our pre-wired harnesses are now wired using solderless connectors. This means that you should be able to install the harness without any soldering. A mini flathead screwdriver is included to allow you to screw down the terminals on to the necessary wires. Read more here.
(*If you are installing into a bass with a barrel jack, you may need to solder a couple connections) or grab one of our prewired barrel jacks)

Artists: Vivian d'Souza, Fernando Vallin, Paulo Roberto Diniz Jr, Will Birckhead, Travis Carlton, Scott Pazera

Just wow!

I was on the fence whether I should get rid of my bass. I recently bought a new one of the same brand (Roscoe) and just really preferred its tone over my older one. Someone recommended I install a Nordstrand preamp because he said they work well with Bartolini Quad Core pickups. Boy was he right! I feel like I got a new bass

Exceeded my expectations

I’ve always wanted to install Nordstrand preamp in my bass. I kept the stock pickups & added this jawn. I just wanna say the tone is amazing and that’s before you dial in the tone knob & boost the mids. When you add those two, you get that bite with clarity & growl. Best modification choice.

Nordstrand 3-band pickup (3b-4B)

Wanted a preamp to replace the meh stock Darkglass pre in a Spector EuroNT. Very helpful exchange with FBT rep helped me zero in on the Nordstrand 3b as a suitable replacement. Transaction was easy. Then there was a slight issue in installation (Spector Euro has narrow holes for 2 pots), and another exchange answered my questions about that. These guys know what they're talking about and their prices are competitive, and it was an excellent customer service experience. Most importantly the Euro+Nordy sounds *incredible*, it's really the sound I was looking for -- their advice was spot on. Will definitely look to FBT for future hardware purchases!

The preamp came with non solder connections not pictured on the site. No soldering needed for most connections (I kept the existing output jack). It is very transparent and the combination of active tone controls plus a passive tone makes this very cool. All very ‘real world’ controls.

Nordstrand Preamp for Ibanez GVB36

I ordered a Nordstrand 3-band preamp from Fat Bass Tone to replace the Ibanez preamp in my GVB36. They had it in stock and it shipped right away. Install went flawlessly and the result was a major improvement. Thank you Fat Bass Tone for your excellent customer service! My new go to source for everything bass guitar related.
