Re: ibanez pro line
I once had an old Roadstar with a similar problem. My hack solution was to glue another piece of pickguard-like plastic to the bottom of the pickguard (underneath the busted part), and then drill a hole through that for the shaft. That actually worked fine and the knob did a decent job of concealing the half-arsed fix. Depending on how pretty a repair you want, silly solutions like that often work. However, a ProLine 1770 is a very nice guitar and might deserve better.
