I have a Fernandes strat copy guitar. My girl wants to get me a prewired pickguard assembly for our 3 year anniversary. I guess I really have 3 questions. Do I need to take the guitar's size/scale into consideration? Will any "strat" assembly fit? I haven't taken the existing pickguard off since it's my main playing guitar. Is it just routed for single coils or is it wide open with room for full sized humbuckers? Can someone please recommend someone who does custom wired and switched assemblies? Thank you in advance.
