I was at GC waiting for my friend to do the DrumOff (what a stupid and biased competition...) and I played an SVT Classic through the 610hlf. Now those of you that know me know I'm not a big ampeg fan... But this was good. Maybe I just absolutely despise the 810e. The ports really make a good difference to my ears. I know a lot of people don't like tube heads through ported cabs, but it was pretty good! That being said, I can't wait for my mesa 810 to get here... because it is ported and has the massive speaker area of the 810. It's got the punch and the booty to back it up. I left with intense GAS for a tube head though. It's been too long since I sold my Mesa Bass 400 in a spell of youthful naivety (for a LMII no less ). With all that being said, if I showed up to a gig and the backline was an SVT Classic through a 610, I wouldn't be disappointed at all!
