ill probably go to guitar center and try them both. Is there any difference in quality?
The Custom will actually be higher quality (better hardware cast, higher grade wood, etc). It's not a hugely noticable difference, but if you were looking for the most value for your money and something to potentially record or gig with, you'd want to get the Custom, no question.

That said, personally I'd get the Standard Plus. I'm already good for gig-worthy instruments and trans black burst finishes over flame maple are too good to pass up.
