Hi
Although I have a 8008 as emergency backup (and practise amp) to my 9200 I would recommend against getting one as your main amp. *
All the best tones in rock are from
valve amps and valve power amps e.g. the classic EL34 valve power amps.
Although I have only used the Peavy 60/60 once, I have heard good things about it and it seems a good power amp.
As for a preamp I would look at three; ADA MP-1, Marshall JMP1 and Mesa boogie Tri-axis. *The JMP-1 might be best for your needs (
Dave Mustaine uses them for example).
For a combined preamp and effects have a look at the Rocktron range.
The thing with rack stuff, and I speak with 8 years experience, is that you want something which sounds great, is not going to break down and is easy to carry around.
Email me personally if you want some more information/advice etc.
Cheers
Simon
