Roland GR-300 Polyphonic Guitar Synthesizer (ALL FUNCTIONS WORK but untested with Guitar)


Roland GR-300 Polyphonic Guitar Synthesizer

Unit is from a Recently Shut Down Recording studio, does not come with guitar cable.

The GR-300 is an analog guitar synthesizer released by Roland Corporation back in 1980 and continued to be one of the best pieces of analog guitar synthesis equipment for a long time. Roland advertised the GR-300 as a synthesizer that is able to produce effects and nuances that were impossible for the keyboard synthesizers of the time to easily produce.

Any guitarist can play the GR-300, using all standard guitar playing techniques, including: hammering, glissandos, harmonics, chopping, etc.

The GR-300 produes effects and nuances which keyboard synthesizers cannot easily produce.

It is very easy to produce from simple or complex solo sounds to the sounds of a huge band or orcehstra. All major functions are controlled with foot switches and require no hands.
