The JEM-JR, also known as the JEM333, is a solid body electric guitar introduced by Ibanez in 2002. It is a signature model of American guitarist Steve Vai and part of Vai's JEM series. It was the most affordable JEM model. In terms of specifications, it is more similar to the RG350DX than the JEM7V it's modeled after.
The JEM-JR was discontinued after 2012, but a similarly named model, the JEMJR, was brought out in 2015.
