    I am building a Frankenbass with the body of a Squier Jazz as the foundation. I want to put a pre-amp in, which is causing me a little anxiety, since the pots that are already wired into the pre-amp harness are from a Warwick. They don't fit through the holes in the original chrome control cavity cover.

    I could try to route out the metal piece, but since these parts are relatively inexpensive, I figured I would just buy a new control plate with openings sized for the Warwick pots.

    However... I either can't find can't find any measurements listed for replacement plates (which leads me to assume they are identical to the Fender/Squier standard) or the size listed is the same as what's on there now.

    Anybody know of a source for J-Bass control plates with alternative control hole sizes?

    You can enlarge those holes with a reamer or a 3/8" drill bit if you're careful. It's standard practice when replacing pots on Squiers.

    I had been hoping to avoid that since I'd have to buy/borrow the tool. But it's looking more and more as if that's how it's going to be.

    The reamer is only a few dollars, and I purchased one for the very reason you need one. Since I got it, I've used it for a bunch of other projects. It's a good tool to have.

    Do you remember where you got your reamer? I looked for one, all the ones I could find locally were slightly too small, I think they maxed out at 1/2", and I needed 9/16. All the larger ones I found online were pretty expensive.

    Home Depot. They had tons of them in different sizes. The one I got was to make a Japanese Fender control plate fit with normal sized CTS pots, and when I got the holes big enough, I still had plenty of room to go bigger. I asked a local repair person here what to do when I had to rebuild that wiring harness for a friend, and she showed me the reamer she used. I didn't want to use the mini pots that the MIJ Fender basses had at the time.

    Dang! My local HD sucks, it's about half the size of most HD stores, their inventory is pretty thin. I know I looked there a while back. I don't see anything that looks like a traditional tapered Luthier's reamer, but they do have step drills graduated in 1/16ths like this one, which would have worked nicely widening my tuner holes to 9/16". Something like this might work for the OP. They have the advantage of being self-centering, but I'd still want to use a drill press through a metal control plate.

    Check the Home Depot website. If your local store doesn't have what you need, the website should, and you can order it.
