Cap Value

With our Prewired Jazz Bass Control Plate, you can choose and customize your Tone Cap options easily. Lower values (0.0022mfd and 0.0047mfd) will give you minute tone control and allow micro-adjustments to your basses’ tone. Larger values (0.02mfd & 0.047mfd) will start affecting the tone earlier in the tone pot rotation, and cut deeper into your basses’ midrange, giving you a darker tone.

If you’re unsure of what tone cap to choose, we recommend a 0.022mfd, which is a good middle ground.





Installation of our Prewired Concentric Jazz Bass Control Plate is very simple. Your pickup’s Black wires go to Ground and can be safely soldered to the casing of each pot. White Wires solder to the middle lug of their respective pots. That’s it! See below:

The only wires that need soldering are the White and Black wires from the pickups. The rest is taken care of for you.

    Perfect fit & finish – nothing short of what was expected. In regards to the sound quality: A+ Very cool vintage voiced in my opinion, clean but also with a hint of dirt when pushing it. All expectations met. I’ve installed this in a anniversary Japan spec. Jazz bass – with a 3 wire pickup configuration – so I had to reach out to support. Reply & help came within 24h. Top notch.

    Quality is amazing and my bass sounds great! I bought it with the 0.022mfd tone caps for both pots, and together with the fralin jazz bass pickups. Installed it in my squire modified vintage ’77 jazz bass, it really transformed it into a great sounding instrument.

    Solid American-made construction. Paired with Fralin’s J-bass pickups, the controls gave me tone and volume control that far surpassed my expectations. Worthy of the original Fender sound every musician seeks.

    Bought a Fender American Pro ii Jazz bass and to be honest I’m not quite happy with it so I’ve been doing some mods lately.

    First, I bought a pair of Fralin 60s Jazz bass pups and swapped out the factory fitted V-Mods ii and the difference is night and day! a
    I much prefer the tone from Fralin 60s, punchy, articulate with the iconic jazz bass growl and it does not get muddy when I rolled it off a bit. I’ve always wanted to have a jazz bass with stacked knobs so I finally pulled the triggered and have it installed on my pro ii jazz bass.

    OH man I tell you what the tone I can get out of this combo (Fralin 60s + stacked knobs prewired kit) is unlimited and the installation is simple all you need is a soldering iron and I got it done in just under 10mins. If I was going to buy another J-Bass I would definitely fit it with another set of Fralin stacked knobs prewired kit!

    Build quality A+++
    Components used A+++
    Tone A+++

    You guys are awesome. I just installed my pickups and control plate into my Sire V7 fretless, and it sounds fantastic. So much more bottom end. So much fuller sounding. Looks sharp too! I’m an absolute beginner with bass mods and the flags ya’ll left on wires to show what to solder where, made it so much simpler. The e-mails you sent while waiting for the build to be complete were also helpful! I can’t thank you enough and would recommend Fralin to anyone and everyone.

    Purchased the control plate to go with the Fralin split pickups previously installed on my jazz bass.
    Ordered the 0.022mfd oil caps on both controls. Easy to install. They actually put temporary wires with flags attached to show where to solder the pickup wires to the pots. The tone is a vast improvement over the stock controls and having a separate tone control for each pickup allows for greater range. My bass has never sounded better.
