Hi,

I'd like to know if uneven rails could generate intonation issues or notes out of tune or only affect mouthpiece response.

Thank you in advance,

Luis Pablo

(Updated :))

The vibration modes of the reed will be altered. The results are unpredictable, they should be carefully analyzed for each mouthpiece by sofisticated experimental techniques. By assuming a "perfect" reed (which doesn't exist) sound alteration can be generated by the superimpositions of several undesidered vibration frequencies. Some partial can be overemphasized. Problems (usually) or advantages (some time mouthpieces have strange behaviors :? ) will affect the mpc general performances. Experts in this field can help us in finding the right answer.
I hope this can help.

Some technicians add uneven rails to tune (add) resistance. How uneven the rails are is another issue.

I don't see how uneven rails could cause a piece to play out of tune unless the embouchure was forced way out of the ordinary.
