Does anybody have any information on "Resonance" custom mouthpieces. My teacher plays on one (the 2c, about a bach 3c comparison) I tried it and I loved it. I asked him where I could get one and he said he got it before the maker moved to california but he belives the business is still open. I tried a goodle search on Resonance mouthpieces and couldnt find anything. If anybody knows anything Id greatly appriciate it.
try metacrawler.com, use "altschuler resonance trumpet" you should get a trumpet.dana.edu website in the results I did not take time to sort it out but it should get you started
