Testimonials

My problem was being a 1/4 tone sharp above the staff with most lead type mouthpieces.Then Dave Harrison's Wedge MPs arrived. Having the right MP configuration for the horn and my way of playing makes correcting that sharpness very manageable and predictable. If I had not gone on this safari--and to be honest several folks thought I was wasting my time--I would have greatly limited my playing ability.
