Wiring harness upgrade for Fender P Bass with G & L SB-1 style electronics!

Upgrade Your Fender P-Bass with Pro-Level Electronics Inspired by a Classic Era!

Transform your P-Bass with a professionally crafted wiring harness that brings the legendary tone of vintage 1980s designs to your instrument. This premium drop-in solution is tailor-made for Fender USA Precision Bass models and draws inspiration from the iconic electronics pioneered by Leo Fender himself.

What makes this harness special? It’s all in the details:

• Smooth Volume Control: A .001 µf treble bleed cap ensures your highs stay crisp, even when rolling back the volume.

• Expressive Tone Control: Featuring a 0.1 “Green Chicklet” capacitor (can substitute for a vintage Sprague by request only) paired with a 6.8kΩ resistor, the tone circuit offers an incredibly musical taper—smooth for the first 75% before plunging into rich, dark depths in the final quarter turn.

• Premium Components: Hand-selected parts like CTS solid-shaft pots (can substitute for knurled by request only), a Switchcraft #11 jack, and vintage-style Gavitt wiring provide reliability and exceptional performance.

Each harness is meticulously hand-built in Orlando, FL and ready for an easy installation—no soldering required. Elevate your bass tone with a proven design trusted by players worldwide.

Now, for the fine print (please read):

*** We realize once these mods and harnesses are in place, no one can see them. We build them as if you have a plexiglass control panel and EVERYONE INCLUDING YOU can see them. If you HAVE to have or not have certain pots or capacitors, you can let us know before (never after) purchasing and we will do our best to either accommodate or explain why we can’t/wont. Just note this so there are no misunderstandings or confusion later. :-)

**** Please allow APPROXIMATELY 5 - 7 business days (no sat/sun are not included) give or take a few days!, to build, QA, wrap and box, then ship, starting from the first business day after your payment clears. So, if you make payment on Friday, your time starts that Monday. I’m sorry to the 90% that get this, it’s for the others that don’t read and think this is next-day Amazon warehouse deals, and/or those that can’t calendar days, etc and are impatient. Thankfully, they are not the majority or we’d quit. 😂  We are slammed with work and this is the fastest we can all get together na ever these out to you all without sacrificing quality, which is the major part of our DNA, along with Tone We sacrifice neither If this bothers you, don’t buy from us.  Please dont send us messages asking about the timeframe as 99% never read the above paragraph. 

No refunds or returns.

Every single item we ever make goes through a live QA process that involves a live tech, on an electric guitar and tube amp plugged into your mod/harness to test every aspect of it for full 100% functionality and audible satisfaction - before it’s wrapped, boxed, and shipped to your front door.

Everything is made to order and includes the easiest diagram ever to connect with ease and confidence.

Thanks for looking! 🔥🎸🔥
