Hi, how are you? Got mine booked in over December – also looking at shoe-horning the amp into a larger open-back 1x12 Session ext. cab I have and adding a loud bass heavy speaker like the Tonker.... or perhaps I wont have to with the Retrotone? Stewart made mine from 80's left over parts in 1998 in the original format (but with a Celestion GT100 instead of the G12H 100 or later Fane speakers) and it needs to be used!
