I'm in the process of upgrading my stock Ibanez RG8, so I've recently bought:
- Hipshot Griplock Locking Tuners for 8 String
- 2 500K Potentiometers
- 5 Way Switch for HH configuration
- Extended Guitar Jack
Otherwise I'm saving for the remaining two components I still need (Hipshot Bridge and DiMarzio D-Activator Humbuckers).
