Going to invent a guitar that has magnets below the strings and when the strings vibrate within the magnetic field it will make an ELECTRIC SIGNAL thus I will call this Magnet Guitar a MAGNETAR

*wait. I’m being told…*

I’m happy to say magnetars are already available.

I'm not a music historian, but I believe the magnetar is a refinement of the electric violin invented by a young Albert Einsten while he was working as a humble patent clerk in Sydney.
