This week in distance learning for guitar building was Brian May week. We watched videos on Brian May’s Red Special, the guitar him and his father built that he still uses to this day(I did not know this). May has six switches on this guitar that allow him to turn on his pickups and then switch them in and out of phase, he uses the technique a lot during Bohemian Rhapsody, a 2PDT switch is used for this.
