At the rehearsal studio my band practices at they have both a carvin B800(with carvin 2X10 and 1X15) setup and an Ampeg svt 400H with an SVTHLF. The ampeg is much better, imho. I know the ampeg setup is much more expensive but it gets a great sound at almost any setting. With the carvin i can't seem to dial in a sound that is quite right. I also own a GK 400IV head which i like much better then the carvin, but its not quite as nice as the ampeg. What style of music do you play. I play indie rock with a P-bass and a pick the carvin might be great for other styles/genres.
