The Roland GR-20S Guitar Synthesizer makes playing high-quality synthesizer and instrument sounds from your guitar amazingly simple. Ever wanted to thicken up your guitar sound with a warm synth pad? Or how about a screaming lead sound that puts you in front? Just select the type of sound you want using the Bank knob then choose a sound variation using the Number/Value dial and start playing. With the Roland GR-20, it's easy to tap into the power of guitar synthesis.

Guitar Synth, or Compact Pedal?

With the GR-20 it feels like both. (The Roland GR20S is also compatible with the earlier GK-2 Divided Pickup.) Selecting a sound is like choosing an effect. First, select a sound category using the Bank knob. Categories include Strings/Orchestral, Wind, Brass, Bass/Guitar, Organ/Keyboard, Piano, Synth/Lead, Voice/Pad, Ethnic, and Rhythm/Percussion. Now you can select individual sounds using the Number/Value dial.

Roland's Finest Sounds with Exceptional Tracking

At the heart of the GR-20 is an advanced sound engine based on Roland's professional synthesizers. Sounds can be played with up to 48-voice polyphony for full, rich-sounding patches. And the sounds are equally impressive. From expressive string ensembles to spiritual tabla loops coupled with sitar--all with adjustable attack and release. Sophisticated DSP makes the Roland GR-20's pitch detection ultrareliable, so you can strum with confidence.

Take Your Guitar Playing Further

Want to create a sound that's all your own? Try blending the natural sound of your guitar pickups with the GR-20. Thankfully, the optional GK-3 Divided Pickup (see accessory box on this page) makes this easy via a larger and smoother knob. Imagine playing chords and then slowly fading in a swirling, breathy pad to create intensity. Or how about playing a distorted lead on your guitar with a thick synth lead sound? Now take this a step further with the GR-20's Patch Link function. It allows you to easily assign GR-20 patches to match effect patches in MIDI-capable processors such as the BOSS GT-6.

You won't want to every play WITHOUT one again!

Comments about Roland GR-20S Guitar Synthesizer - No Pickup:

I am NOT a new user of the GR-20. I have used mine now for a year. I will NOT gig without it! Wether I am gigging with our 5-piece band, or our two-piece small club ensemble, I have found the GR-20 the most significant piece of equipment I have owned. I use alot the piano, strings, organ and flute sounds extensively. I love playing, for example, a slow song, then slowly press the pedal and bring in the string ensemble. Fantastic! And now I don't just do guitar leads any more, I can do a Flute lead, sax, organ etc.. My GR-20 is incorporated on my Fender U.S. deluxe Strat. I strongly recommend the GR-20. You will be a believer!!


Great synth!

Comments about Roland GR-20S Guitar Synthesizer - No Pickup:

Great product. easy to set up and use. Some patches are outstanding (sax, flute, some of the ethnic instruments) others sound pretty synthetic but overall it is going to save me from having to learn another 10 instruments for composing what I like. I never played a synth guitar before but the Godin guitar works great with this system and it is easy to get outstanding new sounds with this combo.
