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.

FREQUENTLY ASKED QUESTIONS

How do you connect the DiMarzio 60’s pickups to a pre-wired passive harness that uses solderless connectors?

On DiMarzio 60's pickups, specifically - Pickup wires bare and black are ground, white is signal (hot). Pickup grounds can go to connector labeled pickup ground in the diagram. The other dedicated ground block can be for your bridge ground wire, and any additional ground wires you may happen to have.

Will the Volume-Tone Prewired Passive Harness fit in the electrics cavity of a Mustang bass?

Yes.

Can the Pre-wired passive harness be wired for lefty basses?

Some left handed instruments have controls that turn anti-clockwise for ‘more’, while other lefty instruments are wired the normal way. The harness sold on FBT can only be wired the normal way due to the right hand taper of the pots we use. You would want to seek out ‘left hand taper’ pots for them to be effectively wired lefty.

Will the pre-wired passive harness work on a Warwick passive bass?

The standard passive harness would be fine for Warwick, but here’s a few notes. 1) You may have to ream out the pot holes to accommodate the 3/8” bushings of the pots used and 2) for it be a fully solderless install you would need to add a pre wired barrel jack to the order, due to the type of jack used in Warwick.

PREWIRED V-B-T HARNESS

This went in my '00s Aerodyne PJ and it feels like a new bass. I was having an issue where I would turn the both volumes all the way down and could still hear myself playing through the amp, also the tone could never really give me what I wanted. New harness is night and day. SO EASY and quick to install. I love the blend control. Being able to dial in a little more bridge pickup in the middle of a song live without missing a beat is real nice, and the single volume is just easier with sweat dripping in your eyes. The combination of sounds between the new tone and blend pots really makes it feel like I got at 2 new basses This bass went from hanging on the wall to coming to practice with me every week. I will absolutely be back for a stacked harness to revive the Squire Paranormal 54 if I ever decide on pickups
