Re: Liquid accumulation under pads

Sometimes (but not always) the (very common) problem of condensation can be magnified by small micro leaks- pads that are seated well enough to play ok, but not QUITE sealing perfectly. When the tech puts the clarinet through the Magnahelic test we're talking 2% worth of leaks. These tiny leaks cause low pressure nodes in the bore (remember, air does not flow through the bore, pressure waves travel through the bore) that aren't enough to make the notes unstable (like an obvious leak would) but attract condensation.
I've actually seen an experiment that proved this happens, was super interesting but alas not on youtube.
Low pressure nodes in the bore encourage condensation to collect at that spot, who would have known?
