Ok, I play a 8335RGS and like the horn, but would like to have some tweeks. I would like a more open feel, more resonance, and a more open upper register. I presently play in a band with a section of Bachs, Schilke, and a Bel Canto. I feel like I have to push to hard to "fit in" with the section. I dont think the tone is bad, but would like an easier feel. In big band lead stuff I have no problem getting over a band, but want a more open upper register (above high C). I have emailed Charlie Melk about a rounded slide and gap adjustment, but he doesnt seem to be sure it will help. Of course he hasnt seen the horn yet. I just dont want to put the time and money into this horn If there are no tweeks to make it better. I like the horn but............. Anyone had this problem? Did you find a solution? Thanks.
