Hi Guys! Having problems with my Besson Prestige euph ... its one of the newer models from buffet .... About a year ago i started to notice my valves were seemingly getting worse ... i took my euphonium to Steven Mead who found that the instrument had seemed to have a knock and had actually compressed....the brace on the bell had pushed in causing the pressures to be out ... i had it fixed at £300plus and all was well and good. Last week i noticed the same thing had happened and the brace has pushed into the bell again causing it to dent! Now i didn't think i had dropped, banged or done anything untoward to my euph the previous time this happened ... but i certainly know that i haven't done anything which could cause this damage this time around! Is this a weakness a known fault or what? To tell the truth im seriously miffed! What do you guys think i should do?
