Quality Neutrik type of 'open chassis' jack socket you get in many guitars like Epiphone, Ibanez, Squier and Yamaha or just about any guitar where the jack socket fits onto an access plate or scratchplate. Some guitars have the jack socket mounted on the front of the body directly through the wood, like some models of SG, so this might not be long enough for that one. Take a look at the picture of the dimensions to check first.
