Well i went to the local Guitar Center to see if there was a BB in stock and of course there wasnt.... i tried the 400+ since it was there so i could at least play A mesa setup again. IMHO i didnt really think the 400+ sounded any better than my Carvin R1000 :scowl: which kind of disapointed me. Since there was nothing else for Mesa to try i told myself i was trying Ampeg stuff since it deffinitly seems a lot more available maybe they deserve my business more.. Well i played the SVT 4 Pro and after tunning in the knobs and running through an Ampeg classic 810 i was playing the nicest sounding combination ever between the 4 pro/810/Warwick Streamer. It sounded AWESOME. Now the one main thing i still like about the BB is that it has an over drive channel which the 4pro doesnt. I talked to the salesman and he said that the SVT 5 had a over drive channel instead of graphic eq and that would be something to look into. So i am wondering for those of you who have played the 750 and the 5 pro which is the better amp? I guess i was caught into Mesa stuff until i played that mesa today. It was INCREDIBLE haha. Thanks in advance.
