I was gigging last night and at the end of the last (fortunately) song, I saw out of the corner of my eye something fly past me then the sax sounded not right at all. I couldn't see anything wrong and after being on hands and knees in the dark looking for a spring I found nothing so I packed up the sax and had a look at home this morning. Turns out the little pad on the top of the neck (octave key bit) had popped off! Is this something easy for me to fix, if so do I just buy one from a sax shop and what glue etc do I use? Or do I need some sort of special sax pad presser to stick it on firmly enough? Or should I just take it to a sax shop and get them to do it if it's an easy job? Any advice very welcome. Thanks (I'm in North Devon if anyone knows a sax fixer place not too far away that can do this).
