ObsidianWire for Jazz Bass® Loaded Control Plate CHROME

I was skeptical as to whether or not this would make a difference. As it turns out, my worries were completely unfounded. This was an amazing upgrade for my 2006 Squier Vintage Modified Jazz Bass Fretless.

The installation was very easy, the hardest part was putting the wires into the harness itself, but that was likely more related to my age and terrible eyesight than anything else.

The full-size CTS pots were a superb upgrade and the harness has reduced the noise my Jazzer produces.

I did have to get a USA-sized control plate and knobs, but I knew that going into this.

I will be buying another one for my Squier CV Precision, I like it that much!

If you are "on the fence" here, go ahead and buy the harness. If you have a Squier Jazz bass, save yourself some trouble and buy the entire package.

I replaced an active preamp with passive switch on my favorite 5-string jazz and this thing sounds so good. More articulate and open sounding vs. how it sounded with the pre bypassed. My bass, a BassMods K534 is known in gospel and funk for a hi-fi jazz sound and super easy playability. However, I'm a rootsy reggae/jazz/soul player and wanted to capture the classic jazz tone for mostly finger styling playing with flatwounds - installing this pre-amp did it. This gives me a modern, super easy playing 5-string with a rich jazz bass tone with more clarity and range through the 2 volumes and single tone knob. I like modding basses but soldering is something I struggle with. I'm all thumbs when it comes to wiring but I was able to do it with some trial and error in under an hour. If my pickups had more identifiable wiring, it would've taken me alot less - not the fault of the harness. Those instructions were clear and the unit is super solid.

I love the quality and ease of install. My previous setup looked like a bird's nest but now it's neat and clean. I notice greater variability in volume and tone.

Worked well with new fender ultra noiseless pickups. Mounting plate fits Japanese fender jazz bass which was a nice surprise. Cable attachment is a lot more secure than my old harness. I like the Larger volume knobs.

Excellent product was very easy to install. Solderless connection made it quick & the mounting plate fit perfectly in my Sire v5 jazz bass.

Swapping the controls out of my bass to rge obsidian was a breeze and it made switching pickups even easier. I highly recommend them.

The installation was a breeze and the sound on my J-Bass improved.

After years of soldering everything myself and swearing at my eyes going bad, I put one of these harnesses in one of my Jazz basses. What a wonderful process and sound. The one in there had all scratchy pots and now it's perfect.

It is my first time using a product like this. It was super easy and everything sounds great. It was a pleasure working with the company. They were fast, responsive very pleased. I look forward to working with them again. I would recommend it.

Ever since I discover Obsidian I never look back, all my basses are equipped with em, and now I had the chance to install one on my first J bass and just as expected, greatest quality, amazing value, and I can safely say the greatest upgrade you can do on your instrument

Thank you Obsidian

Awesome product! Super easy install. Works flawlessly. No dead spots, scratching, hissing, or any other anomalies. Couldn't be happier. Fretless Jazz Bass with passive Bartolini's.

Really nice and neat loaded jazz plate, Sounds great

Dropped right In should have done this a long time ago

This is a top quality product. I got the pre-wired harness mounted to a new control plate. Installation was easier than the removal of the factory plate and controls. The potentiometers make such a huge difference in volume and tone control. This has turned my good Jazz Bass into a fantastic Jazz Bass. If you're on the fence about this upgrade, go ahead and do it. The price is great and by doing it yourself, you're going to save money. And, be proud of tuning up your bass. Thank you, ObsidianWire!

I’m not handy with a soldering iron and this definitely made the process easier. I’m not an experienced tinkerer so I can’t say if it has a greater range of sounds, but it’s certainly not less!

I have built three Jazz Bass variations over the last 12 years, my first one was a fretless, and it never really sounded right and the tone was off. I Finally got around to installing your Vintage JB controls and now it sounds great. I really love your product!! Keep up the great work!

simple, EZ to use and install, fantastic design and tone. Highly recommend.

I had previously used standard components on this jazz bass but had problems.(dead pickup) I thought that the harness (circuit Board solder less install) would be better. As well as sound better, It did!! Im Happy!
I did have some problems with the wire ends from the pickups, not wanting to stay connected but using a tweezer to hold the wire in place did the job!
Very well Made! My wife said so, She is a certified solder and assembly person with over 30 years experience!
She makes things that go in airplanes.

This sounds great and was easy to instal BUT The pots are "too smooth" and they rattle. .. I wanted to love this but, I'm not happy.

I had a bit of a problem with short leads from the neck pup I had to work around.
It felt like I could use a third hand sometimes trying to get the wire in its proper place. But…..
It was well worth it. The improvement in tone is phenomenal. Precise and clear.
This Squier VM never sounded so good.
Thanks.

Noticed the difference immediately! I’m impressed with the quality and feel of the product. Very easy to install and the instant surprise of clear clean notes. I want to do all my basses now.

I’m in my 70s & has taken up learning bass , inexperienced in upgrading the instrument, found on YouTube Osidianwire easy upgrade, no soldering-WOW , so easy, bass sounds much better.

Purchased a Jazz Bass wiring harness to upgrade / replace the pots in a Sire Marcus Miller v5 bass. Worked perfectly (had to splice some ground wire as the grounding terminal was on the jack-end of the harness and the ground-wires in the cavity were too short) but it greatly improved the tonal response and taper-curves of the bass. Do note however, that you will need to buy a new control plate (and knobs) as the harness is US CTS pot-shaft specific and the harness will not fit a non-Fender standard plate. Overall, great product and very happy with results.
