@@ChoppaWhoppa1 If you have a vintage AC30 it may well feature alnico speakers (blue and/or silver)You might try running the new AC through the old/broken in speakers.That may be a big chunk of the difference.If it satifies you a speaker swap may remedy the situation.
@@bootlegapples That would probably made a huge difference, I've sold it now though. I also think the rectifier tube in the vintage ones was an important feature for achieving that classic sag when pushed hard. The C2 just never got into that tonal area at all. Not a bad sounding amp, but not what I was looking for at the time.
