Gr-55 Roland
Es un sintetizador muy bueno !!!
Reviewed in the United States on July 1, 2025 by José miguel suastegui bravo

Great sounds
This is a fun device for a guitarist. I purchased one to play / rehearse songs written in open tunings. In my opinion Midi guitar didn’t catch on because it’s not exactly plug and play- I purchased a GraphTech Ghost system; the accuracy is impressive- The Boss sounds included in tge system along with the Cosmos modeling system creates premium sound scapes If you wanna play Buy one of these Im glad I finally did ... show more

Research older vs newer models for best value
Newer model has better variety of synth patches. Compare cost ahead of time before ordering

Otherwise it is the best guitar synth available for the price
Most of the original patches are just OK and need tweeking. Otherwise it is the best guitar synth available for the price.

Boss/Roland for the win!
Fantastic item. I was a little worried that they would release a new model as soon as I purchased this, but after playing around with it for a little while I am sure I will continue to be happy

Worst owners manual ever.
I got this because I already had a guitar with the 13 pin connection, a Godin (which is tough to keep in tune, but that's another story). The manual that came with it is 10 variations of languages I refuse to learn. I contacted the maker. They don't provide manuals in English. Someday I may use this thing. I've worked with it a bit. I've watched videos. It's a lot of money spent that the executor of my will never recover. ... show more

Me encanta! Un poco complicada de manejar pero es fantastica

Worth Every Penny!
I play the violin. I have a fretted 5 string Cantini Earphonic which is a midi violin and this is the only synthesizer that will work with that model. The only thing I wish it could do, is to be able to hook up the rest of my other violins too it. I could retrofit them with the separate pickup but it would be a pain to change the pickup out or very costly to purchase the pickup for all of my violins. It has a ton of features and it’s going to take me a long while to get through all of the different tones and effects that it has, but so far I absolutely love it. If you have a midi violin, don’t hesitate! So fun with all the different sounds. ... show more
