The Aperture of the magnetic Pickup

We all know that the magnetic pickups mounted on our guitars sense the vibration of each string. However, the details of this often elude us. In fact, the pickup “looks” at merely a portion of the length of the string – just like a camera in the optical domain, the pickup has an “aperture”. This may have consequences on the sound generated by the pickup, and the present article sheds some light on that issue. Because the way the magnetic field is shaped, the aperture is also dependent on the distance the pickup has to the string (i.e. the “height” of the pickup), and thus we also get some info about how adjusting the pickup really influences the sound.  Check out the article on the aperture of the pickup here!

Do the pickup magnets influence the sound of a guitar? … the MAC-guitar may provide an answer …

In 2019 and 2020, we posted 3 articles discussing the Fender Wide-range Humbucker (see in particular here: https://www.gitec-forum-eng.de/wp-content/uploads/2020/07/TZ-Fender-Humbucker-Pt-3-WKM.pdf). In that framework, we showed the central element for the listening tests when comparing pickups: the PUC-guitar … PUC standing for Pick-Up-Change.

Given the persistent (and sometime quite emotional) discussion of the question whether the magnets of the pickups change the sound of a guitar, GITEC founder and co-mastermind Manfred Zollner decided to shed some additional light on this and choose a rather practical approach by designing and building the MAC-guitar … MAC standing for Magnet Change.

His investigations and conclusions are found in this article: The MAC-guitar. Do check it out!
