hi there...

So, i have a Marshall head, and for some reason whenever i adjust the Mids it loses volume. if i readjust it, it comes back.

is it a bad pot? can a contact cleaner fix it?

What Marshall is it?

Yes try cleaner first, if that does not work a new pot would be the way to go.

No you need to remove the chassis from the head shell and get the contact cleaner inside the small opening of the pot. It will take a bit of work to get to it, you may have to remove the PCB to get to it.

Make sure you get electrical contact cleaner like Deoxit, I use the Radio Shack brand and it works just fine.
