This website is dedicated to providing comprehensive, complete and accurate information on vintage Roland 24-pin guitar synthesizers, controllers, and related accessories.
I started this website more than a decade ago when there was very little information on-line about vintage 24-pin synths, and a lot of the information I could find was wrong.
Please dig in and learn more about the first sustained effort by Roland Corporation to expand the sonic tools available to guitar players. You will find photos, technical information, service manuals, owners manuals, vintage advertising plus video clips on a variety of cutting-edge gear from the late seventies to early nineties.
This website is possible because of the many GR users who have helped by contributing photos, service bulletins, etc. to make this resource more complete. Feel free to email me if you have questions, corrections, etc. And many thanks to Dempsey Elks who dug through his Guitar Player archives, and emailed me the original Craig Anderton GR-300 article modification article that comprised the original website.
This site is filled with entertaining and interesting information on vintage GR synths. Check on the links below to some of the more popular or unique pages:
Roland GR-300 This page is packed with tons of material on the classic vintage Roland analog guitar synthesizer, the Roland GR-300. Details, schematics, repair tips, modifications and more, including a summary of the original patent application and an explanation on how the GR-300 works.
Roland GR-700 Get to know the Roland GR-700, the 1980s programmable hybrid digital/analog guitar synthesizer! Again with videos, version history notes, repair tips, recommended accessories and lots of details.
Roland G-303 Fans of the GR-300 also know and love the amazing Roland G-303 guitar synthesizer controller. Popularized by Pat Metheny as his go-to controller for his guitar synth for more than 30 years, this instrument is a real beauty, a classic example of fine Japanese craftsmanship.
Roland G-707 Perhaps the most distinctive and unusual vintage guitar synth controller, the futuristic Roland G-707 is always a visual show stopper, and is a great example of Roland Corporation's willingness to push the limits of guitar design.
Ibanez IMG-2010 More than holding it's own against the Roland G-707 is the highly advanced Ibanez IMG-2010. With its Virtual Whammy bar and easy access to the entire range of continuous controllers, the IMG-2010 may be the most sophisticated 24-pin guitar synth controller ever built.
GR-300 LFO to Filter Modification The amazing GR-300 lacks a feature found on most analog synthesizers, the ability to modulate the Filter with the LFO. Check out the details on the DIY modifications
