U Martinu to je známý problém ze sedmdesátých let u dreadnoughtů. Jedna z šablon byla blbě, takže u části kytar byla kobylka příliš blízko krku. K přečtění třeba:

The only real quality control issue that Martin experienced in this period was that some of the bridges were misplaced, resulting in poor intonation. It is rumored that a simple yardstick-like piece was used to place the bridges, and one out several used was about a ¼" too short. This issue can be righted by moving the original bridge back, installing a new bridge, or by filling and re-cutting the saddle slot in the original bridge.
