Hey all,
I thought I’d share with you that I successfully built a Guitar ¼ inch Adapter Cable for Roland GK 13-Pin connections! This is a cable that allows you to connect a guitar or other instrument with a ¼ inch output (bass, ukulele, etc.) to the Roland GR-55 guitar synthesizer. If you are on a gig using the Roland GR-55 the usefulness of this is that if you don’t have another amplifier and effects, you can access the Roland COSM effects and amp models within the GR-55 and use the same sound reinforcement system that the GR is connected to.
Below is a copy of my wiring diagram that was adapted from a similar diagram posted on Vguitarforums.com by “Elantric”. As the diagram indicates, the normal guitar (or other instrument) signal is transmitted to the GR-55 via pin 7 in the 13 pin plug. A voltage divider has been added to reduce the GR-55’s +7 vdc to +5 vdc to feed pin 8 which signals the GR-55 that a GK pickup’s volume control is set to 10. I tested it and, yes, it works!
I hope this information is helpful to you.
Hi, i have a Roland GR55 synth, and i am interested to get One of this guitar 1/4 inch adapter.
Is there any way?
You have to build it yourself.
Do you know whether the Guitar ¼ inch Adapter Cable for Roland GK 13-Pin on your post at https://christopher-j.net/roland-gk-13-pin-to-%C2%BC-inch-guitar-cable-adapter/ can be used the other way around? In other words, an Adrian Belew Parker has ONLY a 13 pin out which carries the conventional pickup signal on pin 7. Could I plug the 13 pin end into the Parker and then plug the 1/4 inch end into a guitar amp?
Thanks.
It seems that it should work, but I would check with the guys a the Vguitar forum for their thoughts. https://www.vguitarforums.com/smf/
Hello there,
I’m quite interested in this cable but am so technically illiterate that I will not in a million years be able to make this cable myself. I was wondering if there is a way you would be able to make this cable for me? I’ll make it worth you while. Please consider it as this cable will revolutionize my setup.
Thanks for taking the time in reading my request,
Sorry…no. But you might try going to Vguitar Forums and checking with those folks. Someone there might be able to help you. https://www.vguitarforums.com/smf/
