DESCRIPTION

These passive wiring harness are a great replacement for your current bass's passive wiring harness or as a passive replacement for a preamp.

Our harnesses use quality 250k Noble® brand pots, multi-strand wire, Sprague® "Orange Drop" .047 capacitors, and a Switchcraft® jack (stereo or mono, depending on availability).

Harnesses are professionally wired in the Fat Bass Tone shop.

All of our passive harnesses are now pre-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)

M/N style taper used on harnesses that use a Blend pot.  This taper has no volume loss at center detente.

Loaded Jazz Plates are available for 3 knob configurations.

Pre-wired harnesses featuring a StellarTone ToneStyler are also available.

Best Before and After Service and Advice Around!

First, customer service. Max is so helpful and knowledgeable and makes buying and installing upgrades easy and downright fun. I went from a Vol-Vol-Tone control arrangement for a 2 pickup bass to Vol-Blend-Tone and could not be happier. But Max not only confirmed my order and install process, he built a special harness with shorter wire lengths between pots as my control space was quite small. Installation was a snap and it sounds great. Thank you so much!!

FBT for the win!

I had an idea for a passive harness that wasn’t provided normally by FBT. Max and Brian were willing to bring my idea to life and I must say they did an amazing job! I can’t recommend FBT enough!
