I didn't see tony at the last Summer NAMM, but have had a chance to visit many times and catch a few shows. I have seen him do a superb job on pedals. I thing his style preference is the waling left hand his idol, Jimmy Smith, was famous for.
The guy "COOKS" and is a great ambassador of a very special kind of American music. Plus, he's a good guy. He was a good friend of my long-time buddy and B-3 giant, Winston Walls.
Believe me, he chooses to play left hand bass for style purposes only; not because he can't.
