Had a look today.
Nice wee set up but the cab, a Vox Foundation with 1x18 (I believe) was struggling with the output - poss new speaker needed.
The head would need some work as it was cutting out at times and again this could be a speaker issue too.
Great low volume tone though - a studio amp for sure and lovely bit of dirt once you give it some welly not that I could really open it up, like I say, might need to go into a better cab for the full effect/force.
I'd say its a Little bastard beater and for £250 and a once over by a good tech it's well worth the punt if for no other reason than to play Sabbath riffs all day long on some vintage valve gear Only minus is no D.I out (I'm kidding!!)
Marco be good to hear it into the 2x15 you have.
