I had a yamaha ytr2335 lying around, i hadnt played it for a while and the tuning slide was stuck, it was left to be a=440 when i played in an orchestra. When i fixed the slide, however hard i push it in, it seems to be about 40 cents to a quarter tone flat and this makes it very hard to play in any ensemble. And i dont want to make my Bb trumpet a B trumpet by tuning to G# because all i know would be transposed for polyphony. there is no visible deformation but the slide is a little crude now as i fixed it at home.
