Loved the place (and the pub around the corner - The White Swan?). Early days all Basses and Amps were downstairs.
Mid 80's (when it opened) through to the early 90's I purchased a lot from them. '88, I got my first Wal from them (five string). A Sadowsky five string, and a couple of Fenders.
The usual Trace Elliot stuff as well, along with their own brand of strings ?
They used to have some great clinics/demo nights there as well with some top players. I used to live just over the other side of the river, near Tower Bridge, so walked over there quite often.
It was a good social gathering as well, always lots of players to talk music with.
