i had a 40w Ashdown FA
its a nu metal voiced amp
Mushy, bassy distortion.
Its a 1 trick pony aimed at a dead musical genre (hence why you can get the ap pretty cheap if you look on the net)
Very bassy amp, its not too bad with an SD-1 but i sold it on sharpish, nu metal isnt my thing :P
You NEED to try one, its not like a 'normal' amp, it is voiced for nu-metal, if you want to sound like Korn, Limp Bizkit etc then fine, if not, TRY before you buy or stay away, i'm not saying genre voiced amps like this arent automatically cr@p, they are just different..
Built in FX usually poor (as has been said)
Theres a JCM 900 50w combo (as new) on ebay if you search
... id take that over this one (and maybe over the Randall aswell!)
:D
