Hi! I'm planning to get the 5e3 tweed deluxe amplifier from ceriatone.. And I really like the sound of Neil Young's deluxe.. I've heard that he has done some mod's for his amp so it could handle 6L6's or something like that.. Do you guys have any advices to get THAT sound?? and is it possible to get it built with those mod's from ceriatone?? Thanks!!
