    Hello bass peeps.

    If I wanted to add a preamp to a jazz bass and keep it vintage looking, is there a way to put the pots inside the control cavity?

    The bass is a Warmoth with the large covered rear rout. Thinking about adding a two band preamp, with bass and treble knobs . Understanding that it would be a set it and forget it, is there a way to mount the knobs inside?

    Thanks!

    Yes. There are potentiometers that are small, can be adjusted by a screwdriver, and should be small enough to fit in a bass cavity.

    Search online. They’re usually blue in color.

    That’s a good question. Anything you want to, like all potentiometers I assume.

    In your case, I’d probably just have them free floating. Or build a small rig to hold and label them.

    But if they’re internal, they don’t need to look pretty.

  7. You might consider getting a preamp or DI pedal with EQ instead. You could plug into that when you need the EQ & line boost.

    Having it "set & forget" sounds nice, but your needs will change in different rooms.

    You could drill some holes in the back plate so that you can adjust the trim pots without removing the plate.

    Depending on the amount of space available you could even use "screwdriver shaft" pots that are accessible through holes in the backplate (like the "s"-type shaft on this datasheet: Untitled Document). They're basically the same as solid-shaft pots but with a notch that can be turned using a flathead screwdriver. These'll take up more space in the cavity and might be more of a challenge to mount, but they'll be a lot more robust than trimmer pots if you want to adjust them a lot.

    Yep. I've seen trimmer pots that are only rated for 10 rotational cycles, and 200-250 is not uncommon at all.
