I bought an Allparts Ricky style tail piece for my RC-4 kit. However, there's a small dilemma with the tail piece. The screws that are used to adjust the muffler are glued to the nuts so hard that I can't get them to move. So the muffler is un-adjustable.
I'm afraid that if I grab a set of pliers and use raw power to unlock the screws I'll either break the screws or break the threads.
I tried to scrape the glue off the nut and heat it with a lighter to melt the glue but it didn't work. The screws still can't be opened.
I sent an email to Allparts but they told me that they're unable to help me and I should go to a local guitar repair shop or return the tail piece.
Does anyone have an easy solution to this?
