so what are we liking these days? been using current tung sol 12ax7s in v2 and v3 and a random nos 12ax7 cheapie in v1 in my ac14hw1x and i've been pretty pleased. since i had my heart set on some fancy el84s to replace the current mullards, i was wondering if i should look into nos glass for the preamp as well, or just let it ride. the rectifier is an nos ei? of some kind, by the by. again, the tung sol/mullard combo is pretty sweet. but as ever, i wonder. and tinker. and since we're talking v2/v3 here, i'm willing to cheap out if it isn't worth the cost. but if there is a magical tube out there, i'm listening. i generally run it fairly clean to breakup and use pedals for overdrive, but i try lots of stuff, even plugging straight in and messing with guitar knobs. and since we are here, after v1, which is the most important tube, in terms of affecting tone?
