hey guys. I went to Guitar center today planning on getting the Gallien-Krueger 700rb head, with $650 bucks in my pocket. It turned out they didn't have it, but they did have the 800rb. After about an hour and a half of talking to the guy, we settled by him ordering the 700rb for me while I took the 800rb home while i waited for the other one to come. But I can keep the 800rb if I want! So I totally got a steal on this thing. $650 for the $750 head! But I'm not sure if I should still just go with the other one or not. the 800rb works at 300watts for lows, 100w for highs (biampable, which i won't use) and the 700rb at 380watts with 50watts for high. What should I do? go with the 100 bucks i saved or get 80 more watts?
