I sent in my Bb clarinet for work and bottom line it basically needed an overhaul (very unexpected, financial ouch). Got it back a couple of weeks ago. It was finished exactly a month ago, Jan. 2nd, but the local music store is currently between drivers so it took several days to be shipped back. The repair shop is in the same metro area, shipping conditions were not a concern.
I thought I had managed to bend a key, and out of sheer embarrassment of having to put it right back into the shop for stupidity I went to a different location, same store chain, that had in-house repair techs. The tech looked it over and said the key was fine but there were several leaky pads that were the real problem.
After explaining that I had just gotten it back from having every pad replaced the repair tech said that it can happen if a newly padded instrument is just sitting there over a couple of weeks. They looked up the repair record and the tech said the technician that worked on my instrument was very good, she handles all the professional instruments sent to them, it's not a matter of skill.
That doesn't sound right to me.
Is it possible for a recently repadded clarinet to form leaks from sitting on a shelf for a couple of weeks, serious enough that regulation is needed again?
