Hi Harpers, Does anybody have any hat tricks to deepen the sound of a 62'Princeton? This particular amp came with a P12R Alnico,I switched to a Weber C12R ceramic,it helped a little,but not much.the baffle has been replaced,(of course,) i'm thinking of "grafting" a baffle hole over the hole and going back to the 10' it came with,I have a feeling it was set up for guitar,hence the 12',any ideas appreciated.Pete Grissim
