I've had my eye on Roland guitar synths for a while now I finally took home a unit 2 weeks ago to try it. I admit it was a bit time consuming to affix the pickup since you have to adjust, position then fine tune to get an optimal sound. However it does put out awesome synth melodic sounds & combining that with COSM guitar effects plus normal guitar output provides a thick, rich fused sound. It is also fortunate that I have acoustic, tube amps & a PA because it helps to try it in all kinds of media. The best sound produced is a combination of a PA for the 2 synth engines & a tube amp for the COSM & normal guitar output although I can get by with a 2 channel acoustic amp & tube amp. The unit also works well with my DAW, loop & voice harmony stomp pedals. I used to play regularly with a band so combining all my gizmos doesn't make up for that but it's good enough to entertain me at home. GR 55 is worth checking out!
