KAISH Fully Loaded Control Plate Pre-Wired Control Plate with Wiring Harness for Fender Jazz Bass J Bass Black

Adequate pots, dime a dozen, wiring very thin and I ended up shielding the whole back of the plate and replacing the jack.

Just popped this onto an old Japanese Jazz Bass with somewhat dodgy electrics. Works like new now ! Thank you.

I was tasked with fixing and setting up an old/cheap J bass copy for a friend. The bass was in bad shape, and needed some sort of upgrade, so I figured this was an inexpensive option. To be honest, I did not need the plate since the bass had a P-style pickguard. I only needed the electronics, so I stripped them off the plate. To be sure, the plate was solid, sturdy, and looked sharp, so I am sorry I couldn't use it. After I got everything all wired up, I was pleasantly surprised at how great it made the bass sound. The pots all turn smoothly, and do not crackle or pop. The tone control works well. It made quite the difference, and I am really happy I went this route. Sure, this isn't going to equal the same level of quality as the more expensive "name" brand options, but if you're looking for an inexpensive way to fix the basic electronics of a Jazz bass, this harness does the job.

I have used Kaish products before with good results and this jazz bass control plate, pots, and knobs are great too. I was impressed with the quality of the control plate itself and the knobs which were an exact match for a broken knob on my Squier Affinity Jazz Bass. The pots are very tiny though. They might work fine. I don't know. I bought the control plate solely for the knobs which may sounds strange but I had purchased just knobs of another brand for the same application and they went on too tight and didn't go down all the way. They had cosmetic defects too. These knobs were perfect and instead of changing them all out so they would match I only changed one so I still have two left, one big knob, one small. Plus a very nice control plate if I need it later. I don't feel like I wasted money because for the quality I still feel like I got a good deal. I just feel like it's better to keep the instrument as original as possible down to the screws it uses to maintain value. Thanks for listening!

Let me start first by saying I have some experience wiring guitars. I'm not an expert, but I've never had to pay someone else to do my wiring or wiring repair work. Secondly, this is not the first of this particular product I've purchased. The first, a couple of years ago, got me out of a bind dealing with some faulty pieces on a kit build I was making. So, when I decided to update my old Squier "Vintage" Jazz Bass with 250K pots, I felt comfortable buying this harness and plate again so I could do a quick change-out and have the cool retro knobs as well. A cheap fix for a cheap, but definitely usable instrument.So, I spent a few minutes carefully soldering everything into place, plugged the bass in, cranked a knob or two — and got nothing. Nothing from either pickup, no matter how the controls were set. Checked over the wiring really well. Everything was connected and in order. Tried it again and — nothing. Then I touched the lead wire going into the neck pickup pot on the center terminal. By lifting the wire slightly, it started working. Letting the wire go created the problem again. I tried the same thing on the bridge pickup pot and got the same result. When upward pressure was applied to the wire, the pickup worked.I figured there was a short in my wiring, so I checked it out all over. Everything looked OK. The pickup lead wires were older, so I recut them, stripped them and soldered them into place. I still got the same problem. So, I removed all the wiring and ran my circuit tester on everything. This is when I discovered the lead [or wiper] terminal [no. 2] on each volume pot was making very poor contact with its corresponding shaft. [See attached illustration] That's why movement temporarily fixed it. I worked a temporary fix by running a tiny bridge wire from the terminal's solder loop to its circuit rivet in the pot's phenolic wafer. [See other attached illustration] For an easy job, this turned into a significant pain in the posterior.Then, once everything was wired and working, I played the bass a bit and then twiddled the neck pickup knob a little and — you'll never guess what — the potentiometer started sticking halfway. Now it basically works as an on/off switch for that pickup. So, I get to work on it a whole lot more!!Also worth noting, the mounting plate that the wiring harness came mounted to only approximates the Fender/Squier Jazz Bass shape and doesn't actually fit snugly against the pickguard at all. [See attached photo]Majorly disappointing purchase, especially considering the relatively good experience I'd had before.
