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!
