Bill, Thank you so much for the reply, I have a Marshall DSL 50 and 100 watt, and a 1959 reissue,Fender Twin, Fender Super Reverb, Vox AC30CC2X, Fender Bassman from the 70'S and now I will get the Carvin amp. With my Marshall's, I have the full stack with Vintage 30's in it now. That should be ok....Right? Then I have an Avatar 4 X 12" cab, loaded with 4 Celestion Golds.....wired for 16 ohm. Which model of BBE should I get? I saw so many different ones. And one final question, do you hook your Gt-6 up with 4CM method? Or do you go right into the front from the out put of the GT-6.Thanx again for all your help.

Wayne
