So I like the sound of my Fender 300T, Hate the weight! The sound is good, got it new for a steal 3yrs ago, gig out with it only about 2x amonth. Though I love GK's 1001's, I am considering of going to a Genz Shuttle 6.0 to power my Avatar 410 4ohm. Is this crazy, to part with an all-tube head just to with something lighter and has more tone control? I try not to use the Graphic EQ on my Fender 300, but seem to get good sounds on one spectrum and not the other. Though it is my ultimate head, I am getting tired of lifting this into the venues. Not only that but replacign the tubes every 2-3yrs will add up to $200-300. I watched the Bass Whisperer demo this on You Tube-Wow! Is the GB shuttle worth it?
