You can’t stay in this business with just a 1/4” straight plug. The next product to come along was the right angle plug. The big complaints about the Switchcraft were loosening screws that held it together and difficulty soldering the ground to the steel case. We came up with the RF2P that eliminated the screws and had a ground clamp that was easy to solder to. It was the first ever patented 1/2” right angle plug.
