Trace Elliot has always been my holy grail of tone. Love my GP12SMX 1x15 combo. Kicks an immense amount of arse! punch and growl in spades and 580w to play with. Sure they are heavy, but thats not a deal breaker to me. I always find it curious that it is said they have been left behind or bettered tonally, a product of the 80's if you will, I'm only 28 and Trace has always been THE tone. Over and above the Ashdowns, Markbass, Ampegs I've played through.
Edit - have to add I never use the graphic preset, it sounds awful. Just manual control of the graphic eq.
