Let me start off by saying that I'm totally happy with what I play right now, and the sound it makes for everything I play. I could play it forever without a frown, but why not upgrade? I have two options right now for my gas. It's either a Epifani amp (either the 902C or the 502), or a Stingray H, four string. What should come next? I want both badly, but unfortunately, life isn't unlimited money. Right now, I play a MTD Kingston with a Carvin BX500, and two Epifani PS-112's. Help me out. Thanks!
