Passive Wiring Harness

I recently purchased a passive wiring harness (volume, volume, tone) to repair an old jazz bass and the results were amazing. I am a novice at soldering and this made my installation much easier. The bass now sounds better than it ever has.

Pre-Wired Passive Harness

I've installed this harness to my Fender Mexican Jazz Bass. It is vol/bal/tone. I'm really shocked, how good it is made and how it sounds! Perfect, clean soldering, excellent work overall!! With my DiMarzio Area J also dead silent. Dream tone details. Highly recommended!!

Pre-wired Harness, Passive, J-Bass

Very happy with this harness in my '90's "Foto-Flame" J-Bass. The original wiring was ok, but a slight modification I had done many years ago just wasn't what I wanted. I love having a master volume and a blending pot for the p.up's. It gives me just that much more variation and control.
I did have to enlarge the holes in the metal plate for the pots, something one might want to be aware of.
Overall, a simple but major improvement!
Thanks "Fat Bass Tone"!

Harness upgrade really helped my SX Fretless.

Impeccable work on the harness build. I went from separate vol pots in this jazz bass config to a vol/blend/tone, elegant and simple, the tone knob now has a much broader range of usable fluctuation. Many thanks!

Worked like a champ!

I was able to resurrect a 1980s Epiphone Powerbass with this harness and some new pups! I had a technical question, and they got back to me quickly with the corrective answer to my issue!
