I used to have a rack system with an F-2B through a Mesa 50/50 power amp, SF-2, through two 2x12s. Sounded great in the studio, royal PITA to move. I played with a guy that had a 2U rack with the SMS pre and the Carvin 1U power amp. I had the F-2B laying around, so I thought I'd pair it with the Carvin power amp - and I really wanted the tie-dye speakers. So I put together a light, adaptable, stereo rig. I still think the Pritchard kicks ass, but right now I'm having fun with the fullness of stereo.
