Basically left the caller in the car for the last 2 days and I think the temperature may have effected it - was surprisingly hot! It is now just blowing air at me and not squeaking. Now I know there are screws under the body of the caller but before I go tinkering to find the reed, will unscrewing the thing render it useless? Looking at it, it looks a fairly tight thing and I don't want to break any seals (though it may be goosed anyway). It is fairly new so unsure what could have happened in the last 2 days. Body is still sound, no cracks.
Has anyone else had similar issues and taken apart/reassembled the thing without issue?
