Cool I had a 1987 Reissue that I wish I still had. I had Jeff Bakos install a Mercury Magnetics OT, PPIN Master Volume, and a Triode switch. My biggest issue with it was getting that glorious overdrive at band rehearsal without pissing everyone off. At one point I converted it to a 1x12 Combo cab.
My favorite. And of all the years 1974 is my favorite. But all of them (4 hole heads), even the reissues are better than any master volume IMHO. 2nd is the super leads... I've been playing these since they were $300 used and always came with the factory cover.
My holy grail amp, a realistic proposition now i have a reactive load box. There is a late 70's 2203 for sale near me, was tempted but chassis was hacked to fit in combo, now back in a head, and looks, gnarly.
