Walter Barrett uses a Yamaha YP-641. He had a trigger added to it, and he may have had other work done to it over the years. He gets a beautiful tone from that instrument, and it blends well with the Besson that the second chair player uses (forget about me, I'm in fourth chair unless we have five people show up, then I'm fifth chair).
