The guitar is a polyphonic instrument with the six strings vibrating independently. However, because the pickup, which picks up the vibrations of the strings, and various sound devices which add flavor to the sound have been monophonic, the electric guitar could not express the delicate sound qualities of the strings. GR has devoloped the Divided Pickup which picks up the vibration of the strings individually, and has established a system to electronically process sounds, with the string vibrations themselves being the sound source. This is the electronic guitar GR-100.
"HEXA distortion circuit makes it possible to get clean distortion which could not be experienced by electric guitar" GR-100 is equipped with the HEXA Dis tortion circuit which can distort the string vibrations that are divided into six sound sources by the Divided Pickup. The sound distorted by the HEXA Dis tortion is clean, deep, and powerful, with a rich sustained sound and beautiful harmony (even with 9th and 11th chords) which could not be obtained by a regular distor tion or over-drive device.
"HEXA Filter, cutoff frequency, and re sonance for powerful filtering effects" Each sound source from the string passes through the HEXA Filter circuit of the GR-100 as well as the HEXA Distortion. HEXA Filter is preadjusted in accordance with the guitar tuning (E, B, D, A, G), low for the lower notes and high for the higher notes. Therefore, unlike using the graphic equalizer or the parametric equalizer, it is possible to balance the string sounds and create a versatile selection of sounds, from soft to hard, using the Cutoff Frequency and Resonance.
"No requirements to get feedback with GR-100-The HEXA Filter will do it for you" The sound of the electric guitar is deter mined by various physical factors which cannot be judged by eyes and ears alone, such as the quality of the material used for the neck and the body, nature of the pick up, the shape of the frets, and the tension of the strings. We have struggled greatly in search to get what we want. Just to get feedback, we have had a hard time trying to locate the common vibration point, and even after being able to get feadback, we have run into problems such as finding there is only one feedback point, or that different guitars have different feedback points. The HEXA Filter of GR-100 not only changes the tone color, but also lets you change the common vibration point and freely select feedback points by controlling the Cutoff Frequency and Resonance so that you can change the nature and charac ter of the sound as you please.
"How about experiencing the electronic WAH-WAH?'' GR-100 is equipped with three effect controls, and one of them is the Filter Modulation. It enables you to add a "wow" effect onto the electronic sounds regardless of Cutoff Frequency or Resonance, and controls the picking power (stress) with the SENS control and the depth of the "wow" effect with the PEAK control. Furthermore, by using the I nverter swj~' you can reverse the operation and ton~ color of the "wow" effect.
"One-touch electronic vibrato and stereo chorus" The second effect control on the GR-100 is Vibrato. By turning the Touch Vibrato switch ON and OFF, a powerful vibrato effect quite different from a manual vibrato can be obtained. The third effect control is Stereo Chorus which deepens and broadens the sound.
"Direct line-out recording without losing true nature of guitar sound" As the electric guitar amplifiers are made for electric guitars, they are designed to raise and emphasize the higher range, resulting in a thin sound when recorded directly out from line. GR-100 has a wide range and shows out standing performance without losing the true nature of the guitar sound, making it suitable even for studio work.
