I'm sure I read somewhere that only two or three of these were sold in the UK!
Anyway, my valve amp puts out 96w and I've gigged it many times. The vast majority of the time, it has been loud enough, but sometimes I wish I had a bit more volume on tap, on the rare occasion where we were in a large venue but couldn't put the bass through the PA.
I have a louder SS head that I bring to these gigs now, so have all bases covered.
