Hey guys, Im sure to some of you this is beating a dead horse but Im new to Mesa and tube amps in general. I got a single rec series 2 used, its in mint condition but I think I have a problem. I have a new set of JJ 6l6 and a new set of Mesa EL34 tubes, I've tried them both and I dont get the gain that I have heard other singles get. I have no idea on the age of the preamp tubes, could this be my issue?? I can barely get a "rock" style distortion out of the modern setting, and thats at a volume that will make your ears bleed. Im a metal guy, so Im getting an OCD pedal, thanks Fluff for the great vids, but this amp has to have more distortion than Im getting. Any recomendations for preamp tubes would be greatly appreciated, and could someone tell me what each preamp tube is for?? I tried searching the forum but couldnt find an exact answer, thanks a million guys, just trying to learn my Mesa
