The string height is arranged in a curved arc between the first and sixth strings (not flat) to match the curved fingerboard. Can I adjust the GK-3 pickup to match this arc so that the input sensitivity in consistent from string to string?

Do I need to drill holes in the body of my guitar in order to attach the GK-3 pickup?

Can I change sounds (patches) on the GR-20 while playing my guitar?

Can I use Roland guitar synthesizers and divided pickups with flat-wound guitar strings?

Are the GK-2, GK-2A, and GK-3 pickups compatible with all GR-series guitar synthesizers equipped with a 13-pin GK pickup connector?

Can I use the GR-20 and GK-3 with a fretted instrument other than an electric guitar?

Can I attach the GK-3 pickup to a left-handed electric guitar?

The cable from the GK-3 pickup to the GK controller sags, and this bothers me. Is there anything I can do to adjust the cable?

I usually use the Select switch on the GK controller to switch between the GK pickup's output and the regular electric guitar's output. Is there a way to switch pickups using the pedals of the GR-20 unit?

I've connected the GR-20's GUITAR OUT jack to a guitar amp and connected my guitar (via the GK-3 pickup) to GK IN jack. However, I can hear the normal guitar sound only, and not the guitar synth sound. What's wrong?
