I probably have never heard one set up perfectly with the right tubes. I've heard a few I really like, alot I thought sucked. The PCB board reissues sound nice. But I never heard one in person that dropped me to my knees (I HAVE heard vintage Fenders and Marshall that did). What is it about a perfectly tweaked AC-30 that makes it legendary? Would it be better to buy an AC-30 head (I've seen some affordable prices), or go for the highly priced/prized 2x12 combo? Appreciate any info. I have never been down the EL-84 road yet.
