For JTV-89 Customers Only: In addition to the 28 electric, acoustic and electric instruments, you also get five high-gain models exclusive to the JTV-89 guitars based on the high output magnetic pickups loaded into the Custom 1 Bank. Each model is based on a different pickup position, and delivers high-gain guitar tone while allowing you to access drop tunings, custom Dream Rig configurations and more.
Because of this, you will NOT be able to modify or save your own custom settings to the Custom 1 Bank on the JTV-89 and 89F guitars.
