^as long as it works, lol.
but yeah, to get the footswitch with it, it's like £700 for the amp, and around £120 for the switch (that's street, not retail)- i assume you could probably get it for £800 new.
so yeah, good deal, if it's not too beaten up, lol.
it also might be worthwhile asking what speaker is in it- i think the older ones had celestion 70/80's, while the newer ones have vintage 30's (better!).
EDIT: i think machinehead have a second hand screamer- if memory serves, it's £600, minus the footswitch (i assume).
