Tim37 Posted December 30, 2008 Report Share Posted December 30, 2008 So i was tearing down a guitar for a friend of mine today and i managed to mess up both pots while pulling the knobs i tried the t-shirt thing and still messed the pot. btw this is a old lp flat top copy with these Knobs so any advise for next time?

Acousticraft Posted December 30, 2008 Report Share Posted December 30, 2008 They can be tight to get off if they havent been removed for years. I have used thin bits of wood or hard plastic to protect the finish and use a couple of wood chisels to wriggle and pry them off. Hammering tight knobs on can drive the shaft down out of the pot as well damaging them. I had the same thing happen when I tried to fit the knobs on a P bass and the shaft moved down and popped the cover off the pot but I managed to fix it OK luckily.

Ilikes2shred Posted December 31, 2008 Report Share Posted December 31, 2008 I've never tried it, but maybe you could take the guitar out in the cold, or somehow cool off the knobs to contract the metal a little bit.... Or maybe not. Quote Link to comment Share on other sites More sharing options...
soapbarstrat Posted December 31, 2008 Report Share Posted December 31, 2008 Next time make or buy a StewMac knob puller, and if the same thing happens, well, then that was the only way to get the knobs off some crapola pots. Quote Link to comment Share on other sites More sharing options...
Narcissism Posted December 31, 2008 Report Share Posted December 31, 2008 I always use knobs that you secure by tightening a screw on or use an allen key. That way if I need to take off a knob its easy and my pots won't get damaged. Quote Link to comment Share on other sites More sharing options...
Tim37 Posted December 31, 2008 Author Report Share Posted December 31, 2008 yeah i am thinking about swaping the knobs out for chrome ones if so they will have a set screw. that should solve the problem this time. Quote Link to comment Share on other sites More sharing options...
j. pierce Posted January 1, 2009 Report Share Posted January 1, 2009 If you put set screw knobs onto split shaft pots, be careful. When I'm stuck doing that (I haven't found a push-pull pot/switch that isn't a split shaft pot for press on knobs) I cut a small piece of guitar pick (I have some that are just about the same size as the slot in a split shaft knob, sometimes they need a little cardstock shim, too) and insert it into the split part of the knob. That way no matter which way you have the set screw, you won't break the knob, and if it ever works loose, neither will the player when they go to tighten it up. (The best solution of course, is to use solid shaft, or d-shaft pots when using set-screw knobs, but if you're reusing old hardware, that's not always an option.)
