I just picked up a brand new Ampeg BSE410HLF. I went to the music store with my Eden WT400 head and my bass, and tried it out in one of their "testing rooms" and cranked it up. I compared the BSE410HLF and the SVT410HLF. I couldn't really discern much of a noticable difference between the two in regards to tone or volume. Both kicked some serious booty. The BES410HLF won out because of it being smaller, with four removable casters, and the power handling was similar and it was $100 less. Very nice cab. My first Ampeg. Great stuff.
