Internal trim pot - which one/type and how to mount inside control cavity

[Jack_TriPpEr]

I want to try an internal trim pot to serve as a spin-a-split control... so i know specs wise, i want 50K resistance and linear taper.

but i need help in determining what kind of "shape" to buy and how would i mount this inside my guitar's control cavity. I am going to "set it and forget it" so i want to keep it inside the cavity only - no drill hole for external access.

The variety of shapes and types on Mouser.com quickly overwhelmed me - here are a few examples of what i saw.

So, what type/shape do i want, and how do i mount it inside the control cavity?

When I'm doing a project like this, I usually look for little blank boards, like this: https://www.amazon.com/dp/B0778G64QZ/ref=sspa_dk_detail_6?psc=1&pd_rd_i=B0778G64QZ

That's just one example. Google "blank circuit board" and you'll get lots of options. Then, just trim the board down to what you need.

Just get a sealed one. I got a 3 pack for a couple dollars.

I use a 10k because anything above 25k is really unnecessary for this. You’re just matching it up to a known resistance. There is a really good thread in the forum about this.

IME, they are so lightweight that you can just sort of leave them suspended.

you can affix it with tape or let it hand off the wires. I use shrink wrap so there’s no leads exposed to touch.

You seem pretty driven to do this judging by the recent posts. This thread is probably the most informative one on doing this. https://forum.seymourduncan.com/showthread.php?318145-Resistor-Value-For-Partial-Tap It helped guide me to what’s best to do.
