Ozzys first two albums with zakk wylde(We were just talking about Synergy being an ill-fit on the Amps and Cabs forum because it didn't fit the two common topics "How do I get EVH tone" or "My 2 watt amp is too loud." Now we're getting one of them right at least. )
I'm not sure when the 800 really started to get used a lot. I used to think the 800 was the sound I was chasing (having never played one) but later found that a lot of the sounds I loved on recordings weren't the 800 at all. They were late 60s and 70s Marshalls.
This explained why I never bonded with any models of 800's and didn't care for amps I built with an 800 preamp in them. It was the wrong amp.
For me, the BE has the voicing right for 80's hard rock- I'd include the late 70's VH1 in that because I just think Ed was early to the show. I'm not sure what the notable differences are between the BE/Plexi/800. The BE doesn't have the blendable channels of the Plexi and has that in common with the 800. I think it rolls of the lows more than an 800 does, so maybe that simulate the bright channel of a Plexi blended with the normal channel.
Can somebody point me at some stuff known to be recorded with an 800?
Megadeths rust in piece
Most anthrax and slayer stuff
