I got a used 1989(I think) Callet grand PRix from dillons music in NJ a while back. It is silver plate with a raw brass blackburn leadpipe. Lightweight large bore (.470) I originally got it for marching, and ending up using it in jazz and classical that doesnt involve sharp tounging. much more than I payed for as I see it. I only paid around 650 for it, great deal. Yet the model isnt on his website and Ive never heard of anybody ele playing. does anybody else out there play a grand prix?
