I have an Epiphone Viola I am selling... the pots were a little scratchy, so I pulled the control cover off, put some contact cleaner through the pots as I have done before on other basses... no prob. Scratchiness gone.
HOWEVER: now, when I turn any of the knobs up (vol. vol. tone) up past about 5, I get a lot of hum noise that was not there before... not really an improvement over the scratchiness so much. sounds fine at lower volume. I do not think it had the problem beforehand.
I will dig back into it tonight... I am wondering if I mighta pulled a ground wire loose or something? Any ideas? If I can't figger it out, I am gonna take it to a shop, but I would rather not have to pay to fix it when I am about to sell it... but I don't want to sell a defective axe...
Thanks in advance for your help...
