 The sound of a U2 is distinctive of the Danelectro guitar, coming from its
lipstick pickups which when both selected are wired in series rather than the more standard parallel used today by most big brands.Construction materials used by Danelectro in this period are quite unusual for guitar making.The U2's body is made of a poplar wood frame with Masonite used for both the top and back, with the side of the body being bound with creme coloured vinyl.
