The following is a copy of an email I send to the esteemed Mr. Lynch, creator of Asymmetric Mouthpieces, regarding my trial of this Asymmetric Mouthpieces.
First, I want to state that I received EXCELLENT service, and as well great feedback and information from Mr. Lynch upon communications with him, by phone and email.
Here now is the email:
Thank you for your quick response and shipping! I'm sorry I haven't replied to you sooner, been swamped.
I just received the mouthpieces yesterday, and began trying them last night during jazz band. I figured this wouldn't be too bad, considering I'm on 2nd trumpet.
I decided to take time on the Lead M, while my friend Sean, our lead player, is going to take some time on the regular Lead. Here are my experiences:
Upon my initial attempt, I found it interesting to play on, though I had no trouble producing a tone. However, the "lead" aspect of both mouthpieces had not yet clicked with me (I was producing about the same range as on a 3C, about high D-E). I thought,"Perhaps jazz band is not the best time to start trying these mouthpieces," and pulled out my 13a4a to work on. However, I was so curious, and the tone on the mouthpieces was larger than on my Schilke, so I returned to the Lead M again, shortly. With concentration on air, I found my tone centered better and could feel the mouthpiece working better -- things started to click. However, I still found the tone above high C to be a little weak.
After jazz, I decided to sit down with it, and work. Moving the mouthpiece down, so that even less upper lip was present in the cup, I found that I now had it working as I believe it was intended. The tone was brighter, and above high C much stronger than before. My high G was weaker than on my 13A4A, though it had only been a couple hours, so more remains to be seen. I DID notice that though the inner diameter was much larger than on my Schilke, and the cup portion deeper (so I assume the overall volume to be more than my 13a4a) I did not notice much fatigue, nor as much tightening as my 13A4A required (I was switching back and forth, to compare).
I will send more details of my progress, and though thus far I am somewhat pleased with the results, I do hope to see more progress over time.
I did also notice that I could use the mouthpiece with the large rim section on top OR bottom, though for me playing it as a downstream player (with the large rim portion on bottom) allowed for my full range, whereas playing it upstream (with the large portion on top) produced a rounder, "darker" tone, though somewhat reduced my usable range. Neither option required my playing to differ much at all, so I will experiment more with this, because I am curious as to the possibility of "flipping" the mouthpiece orientation to produce different tones.
I do want to state a critique I have about the lead mouthpieces, however, for your consideration. My friend and I both agreed that the lead mouthpieces might perform better in a smaller inner rim diameter, as we are accustomed to playing on smaller diameter mouthpieces for the style, and this has more of a 3C inner diameter. We feel that perhaps there are some advantages to muscular usage with that. Perhaps a smaller diameter mouthpiece could be experimented with? I would be definitely interested to hear about anything done in this direction.
To let you know, I'm going to post a copy of this email on TrumpetMaster.com
You have some proponents of the mouthpiece on there, as well as some curious individuals like myself. I'll keep in touch with both you, and the TrumpetMaster community regarding my trial of your mouthpieces.
