I have a 4x12 Uberkab with H75 and M65 mix which sounds just ok with my other amps. I keep wanting to put 2 vintage 30's in to mix it up. When I plug in the Cameron Sovtek it just gets magic sounding. I'm thinking the Cameron wont sound as good if I add 2 vintage 30's but the other amps will sound better. Ive got other 4x12's so Ill probably leave it just for the Cameron. I know he likes the G12-H30's but cant imagine those sounding as good
