I have watched a few of his performances from him as a young boy and also in present times. His trumpet's tuneing slide and bell crook both look too square to be a Bach. Now his trumpet has changed a few times so I am figureing he has more then one. I noticed that the buttons seem to change styles several times and the squarness of the slide and bell crook vary too but more often then not they are too square to match any brand I can think of.Also the flair of the bell is also different then most modern Bach I am thinking? Is their a Russian high end trumpet maker or is useing a Swiss made trumpet or something like that?
