okay...so for awhile i've been contemplating selling my svp pro for an rbi. i've been comparing my svp to my bddi. at first i didn't think it was a fair comparison becuase the svp needed new tubes. now it has them, and i still don't know if its a fair comparison because the bddi doesn't push my power amp to its full power, and it doesn't have the mid control like the rbi does. so at practice the other day i said i was set on keeping the ampeg. but now i'm thinking again. if i could, i'd have either an old svt, or a mesa 400+. but it's just not practical for me to have a total tube amp right now. the rbi seems to have a bigger/"fatter" bottom end than the ampeg, and seems to sound alittle more "modern". but the ampeg sounds so good too. so i'm starting to think that maybe instead of getting rid of my ampeg for an rbi, i'll just put new pickups in my mia jazz. more than likely, i'll get dimarzio ultra jazz pickups. i just want to be able to get a huge, balanced, tone. for the music we're playing, think along the lines of these bands: hot snakes, drive like jehu, helmet, the melvins (i love mark d's tone).
