I'm going to send him an email and talk a little bit to him will show you his mails if they are any fun. Update; I sent him a mail and he refused to let me try. So i sent him back I see, then i will find another company to make business, not a renamed Kanstul horns that are told the best horns ever. And if i'm not wrong you own and play a bach yourself. See, Alex, every player has their own style and you can't create or find a trumpet that is best for everyone. That's impossible. I have got a friend that's one of the best trumpet player i've met and he plays a bach and like that horn very much. I tried that horn a few weeks ago, it didn't suit me. He loved it not me. You can't create the ultimate trumpet that suites everyone, someone want a thigh slotting some don't and ect. 1. Correction on your site, you need to clean your instruments once in a while with a brush (inside leadpipe and motuhpice). Have you looked in a leadpipe that haven't been cleaned for 10 years? i doubt. Thanks for the info and help, now i know that i will spend my money somewhere else. Best Wishes. Hope it will give him some idea of how he act likes a 6 year old child.
