Thanks for the info re mps. The style of my trumpet Wedge is designed by Gabriel. The difference between it and the standard Wedge is a wider rim. Dave Harrison, designer of the Wedge is a trauma care physician and teaches medicine also--and a trumpet player. We all have our particular facial charistics and Dave designed the Wedge to meet some. He worked with me and my receding jaw and overbite. The advantage of the Wedge for me is that I have more endurance with it. I really don't even try to play above ledger line E. I would rather focus on my tone which has been pretty good with whatever mp I chose to use--probably because the cups were deeper--although my trumpet wedge mp depth is a C. At least Dave's design stopped my mp safari. I was also partial to Mark Curry's mps, too.
