Maybe I'm just indecisive, but I'm having a hard time deciding which SD replacement pups I want to put in a funky old Aria Pro II I just picked up at a yard sale for fifty bucks. I was thinking P-90s, but I'd hate to give up a full humbucker sound. And I wouldn't mind if there was some way to get a cool single-coil split. I wish there was some way I could get all three tones! Any advice, guys?
