Hi Guys,
I bought an Ampeg 610 and an SVT classic (new) and was in tone heaven til the Head gave up after about 4 months, replacement head gave up and I was "upgraded" to an Anniversary 810 & head free...... the couple of gigs I did with the 810 before the Anniversary head "expired" I found the 810 lumpy, thic and slow compared to the 610, ports and a horn seemed to suit the live work I was doing. I found the nearfield sound much better with the 610. Ofcourse haveing 4 810's on a stadium would rock but an 810 in the dog & duck just seemed to knock the back wall in while you can't hear the thing 3 feet away....... Great Cab like...... But I wouldn't touch the heads with a scafolding bar !!
