The cab in question is my Marshall 1960B. It's got the original quad of G12-65s and it sounds really good. However, I'd like more speaker options for recording. Plus, the the 65 watters are not efficient enough to keep up with the silver alnicos in my AC30. I usually don't bring the 4x12 to gigs anymore, but when I do, I can hardly hear it. (In fact, this is one of the reasons I don't really use it anymore.) Has anyone tried Classic Leads and the 65s in an x-pattern? They seem like a good choice in theory (crisp highs, fat bottom vs. the middy 65s), but you never know... Thanks!
