Yep.....both the DST-825 and the DST-830's.

Great amps.....but for some reason i kept killing them. Don't know what it was about them but after having them for a few weeks and rehearsing with them they'd just totally go out on me - they'd throw static and not respond to the midi pedalboard.

The issue didn't seem to be related to anything even remotely normal. Both amps went to techs and both times they basically said they could find nothing wrong with it and for anything further they'd have to send it off to ART in Rochester NY. At the time my band was in the recording studio so that really wasn't an option for me.

I did pick up a DST-8, which is the rack-mount version of the amp. I don't use it but I keep it around in case I want to get farmiliar with that side again.

If you can find one that doesn't detonate on you then more power to you. They have some great sounds in there.
