So my mate in my band can get a Marshall Jcm 800 2203 model and cab really cheap (Original 1982 head I think)

I know a few death bands use the Jcm 800 but not sure what exact model, so what Im asking would this be able to do it with a Ts-9 boosting?

you could do it, I'd get a powerful clean boost instead of a tubescreamer though.

If your getting a deal, buy it and if it doesnt work out put it up on ebay. The prices of Jcm 800s on ebay have rose in the last month.
