If you are into feedback devices, whether it’s a pedal, eBow or sustainer pickups, then you are probably going to be interested in checking out this one. The Vibesware GR-1 Guitar Resonator is a feedback device for electric guitar or electric instruments with steel strings (including acoustic guitars with piezo pickups).
The guitar strings are agitated by a driver mounted on a stand that can reproduce feedback at any volume level. This means that it can be used in any playing situation: on stage, recording, in your room, even with headphones. Unlike the Ebow, which can only drive one string, the Vibesware GR-1 can drive multiple strings at the same time. It is also not hand-held, so it can be applied while playing normally with both hands. And unlike sustainer pickups, you don’t need to modify your guitar.
It is powered by an external supply resulting in a strong magnetic field driving the strings. Feedback can be controlled by the players technique and by phase switching. Feedback harmonics can be controlled by a foot pedal similar to a wah wah (sold separately).
Price: 339 euros (approx. $420). For more information on the GR-1 Guitar Resonator including videos visit vibesware.com.
