by the way, my brother uses a BOSS GT-X 5 in his live setup. He swears by it. I haven't seen or heard it yet, because I haven't been up North when he has been playing recently, but my little brother says it is awesome !!!
Mind you, he has changed everything recently...
-> Gibson SGs
Peavey Amps -> Marshall's
Older Pedals -> GTX-5
It's supposed to be thumping. I don't think he's got used to the sound yet. My little brother said he struts around the stage with his jaw dropping to the floor, he just can't believe the sounds he comes out with himself.
I'm going up in the next month or so to see him play again. I'd love him to let me get on stage with him, but I'm way to shit and not enough confidence to do that yet.
