Though I haven't played that particular pedal, I've used a
Yamaha pedal since 1987 (now one of my backups).
It looks like they offer the 9500 (doubles and single) in Direct Drive, Chain Drive and Strap Drive - all of which have their pros and cons.
I would suggest going to a large percussion store (i.e. Atlanta Pro Percussion) and try out a variety of pedals, including the
Yamaha's. In construction, the
Yamaha DPF9500C (Double Chain Drive) looks very similar to a
Gibraltar I've played - which was a very serviceable pedal setup.
