The JTK1 is a Jet King series guitar model introduced by Ibanez in 2003. It is based on old 'pawnshop' copy guitars from the seventies, the ones Ibanez also produced.
Features include a basswood body, bolt-on maple neck, two humbucking pickups and the Full Tune III bridge. A unique feature of the JTK1 are the two extra up-down switches for coil splitting. Similar switches were also used on Ibanez seventies guitars, but used to be on-off switches for the pickups instead.
The JTK1 is the only Jet King with this body shape. In 2004 another Jet King was released with a new body shape, the JTK2. This new body shape has been used for all other Jet King guitars since then.
