Re: how to use multiple mouthpieces with one neck?
ive used this trick a couple of times, so i cant comment of the long term affect on the horn: when the cork is really shrunk down, take a lighter, a slowly heat the cork up and it should expand it. move the lighter back and forth rather quickly keep the flame a safe distance away. a buddy of mine burned a chunk of his cork because he wasnt paying attention, got the flame too close and wasnt moving it.
best of luck
