Ive been asked by a friend to try and sort out an old Arbiter Alto Sax he has bought, every seemes ok except for the low "c" tone hole , which is warped. Would it be ok to file down and dress the edges as its only warped by a small amount but enough to stop the note speaking ? Or will filing it down alter the pitch of the note?
