Hi, I am in need of some advice, over the past year I have been searching and searching for a decent Besson Prestige 2052/2051 Euphonium. I have recentley decided that I would like to purchase one in the future. For me to purchase a Besson Prestige Euphonium I would need to sell my brilliant Willson 2900TA Euphonium: I was hoping that someone may be able to tell me how much I might be able to get for my Willson 2900? It is in great condition, it has two dents, one on the bottom of the big tubing near the bell (I don't know what it's called!) And the other dent just off the third valve, on one of the other pipes. The bell is also very slightly creased, none of these dents have effected the sound in anyway. It would include a mouthpiece, a soft case and the orginal hard case. I am not putting up this Euphonium for sale yet, but I need to know what sort of asking price I could place, for this magnificent instrument. Thank you for any advice. Kind Regards. Robbie Henderson.
