Hi, i`ve been playing on a wood Bb noblet for a few years in college. Recently I went abroad and could not play for a while, then I came back and the thumbrest it seems is in a bad position, after maybe 20 minutes of playing my thumb starts to hurt and get sore. This is not a movable thumbrest, it is held in by two little screws. Can I take this into a shop and get it moved or becuase it is screwed in and not movable am I stuck with it how it is?
Thanks

won`t hurt to go and ask them.
