Man, I guess I still have to try that D800 to see what its' all about. I was very close to a D800 purchase, when the Magellan 800 sidetracked me. Then the Peavey MM1000 came along I just went with that based on the power and features it offered. I've been very happy with this amp so far. I gigged it again last nite at a Houston premiere blues club. I buddy sat in towards end of nite and he's a awesome bassist and keyboardist. I left my cell ph on stage in my bag, wished I'da took it to back of club and shot some vid, it sounded real good back there.
I've been very lucky in that all the new amps I've bought, several Genz Benz, GK MB800, Carvin B1500, Ampeg V4B, 3 different Markbass amps and now this Peavey have never had issues. I did buy a B-stock Ampeg PF800 that started having shut down issues, so sent it back. I then bought a new PF800 because I liked it so much, figured a new one would be safe. After a few gigs with it, it shut down twice at two different gigs with two different bass cabs, so back it went.
Both times I spoke with Ampeg support and although they were very helpful with all the info they offered, I just decided to send it back. Too bad, as I really liked what I was hearing from that amp. So I ended up with the Ampeg V4B a few weeks later and its been great.
Yeah, I've lost confidence in that Peavey carry bag. It worked fine first few times I carried amp around because I was careful about using it. But with the open side pockets, my tuner and cables fell out twice. And worse, the amp slid out of the bag while it was laying in the back of my SUV cargo area. That single bit of Velcro doesn't seem to secure the flap well enough. I now carry my MM in a very nicely padded backpack which has a lot of pockets so I can carry all my cables, tuner, mic, extension cords, etc in one bag and its' all well secured. I relegated the Peavey bag to backup carry of my GK MB800 which I slide under the seat of my ride as I never gig without a backup amp.
