Over the weekend I played Fri/Sat night gigs powering my mini Bergie stack (HT/EX112) with my old GK400RB. Have been using my Ashdown 500 EVO. Not only did the little GK do a wonderful job and seem more suited to the Bergie 12's characteristic (more punch than fundamental), it even had headroom to spare. I ran it without the mid scoope preset engaged, bass boosted almost full, low mid 1:00, high mid 12:00, treble 11:45 using Alembic and Pedulla 4 strings. My question. I've been eyeing the much more powerful GK1001-II and wonder what benefits I would gain in terms of sound...I'm well aware I would have mucho more power/headroom, but am curious about the sonic benefits or drawbacks. How are the two amps voiced differently or the same. I'd hate to shell out cash only to find I prefer the old sound to the new. PS. Not to be snotty, but I know all of the features of the new heads, I need responses from those who have owned and are familiar with the old stuff and the new stuff for direct comparison.
