A friend and I have been recording together and we are trying to piece together the perfect combination of amps. We currently have a 5150 Block Letter Head, 5150 Signature Head, Marshall 1960 Lead 75W Cab, Marshall 1960 V30 cab, and a Mesa OS Recto Cab. We are also thinking about getting rid of one of the 5150's for a Krankenstein or possibly a Dual Rectumfire. We are looking for maximum versatility in the studio as well as a super thick yet crunchy stereo live sound. If you could only have 2 amps and 2 cabs, which ones would you keep/buy.
