I didnt try the other twins, I just like the 68 looks and the upgraded transformers and handwired tube sockets. So I went with that. Bet the new Vibrolux is cool, just enough wattage and 2 10 inch speakers. I haven't had 2 speaker amp in awhile it sure sounds full at lower volume.How does it compare to other Twins? Does this benifit much from the earlier breakup in these 68 customs, concidering that it's a Twin which generally never breaks up?
