For years I'd practiced sitting on my home office chair. It was only after post Prostate operation problems that I took to sitting down for most gigs. Firstly I got a drum throne and fitted a butt-kicker to it driven from a mix of bass and drums. Then a much taller bar stool with the same device attached. This worked fine as I was always at the back next to the drums. Last year I concluded that I would never gig again to I sold the bits. Recently I've found another band and mentioned that I'd like to sit and play to which the others said, "what a good idea, so will we". In recent weeks I have been trying to recreate my monitoring system and bought an Eich active drum stool. Absolute magic. Everyone, keyboards, sax, bass, vocals and drum tracks, goes through the PA. We have no monitors on stage, so I have the drums in the stool and my bass through a Backbeat. Works well for me.
