Introduction to the Roland STK-1 GR Guitar Controller Assembly:

Roland sought to increase the user base of their guitar synthesizer players with the release of the STK-1, LPK-1 and BAK-1 retrofit kits. Up until this point, the only guitars or basses that worked with the vintage Roland 24-pin synths like the GR-300 or GR-33B were produced by the Fuji Roland partnership.

The STK-1 is a kit consisting of the electronic components from the Roland G-707 guitar synthesizer controller, plus additional knobs, guitar back panel hardware, templates for guitar routing and miscellaneous wiring. The STK-1 was specifically designed to work with Strat type guitars, though it can be installed in any guitar. The STK-1 has a smaller footprint than the larger LPK-1 kit which used the G-303/G-808 electronics card.

Because the STK-1 is smaller, it required less routing of the guitar to install. Subsequently, the STK-1 is more commonly found in third-party guitars than the LPK-1. This was the electronics system in most of the Roland-Ready vintage 24-pin guitars, like the Zion Turbo Synth. Hamer A7 or the Gibson Explorer.
