keyshunter, I have to say I have not ran across this kind of problem , but it does happen at times. The sound in the call is related to the wood density, some boxes are just a slite bit different in pitch because of the piece of wood used. The spring problem , I would package it up and send it back with a note of the problem , or go to a show and stop in at the QB booth with the call and they will either fix it or give ya a new one...BT
