...So I spent a solid couple hours with the new Roland GR55 at Guitar Center in Portland OR and, honestly, I was blown away. Yea, it's got all the obvious Jerry stuff: trumpet, flute, etc... But The coolest part of the unit is the COSM guitar models, in particular the steel string acoustic model - fucking amazing, especially the "feel"... I was astounded how well it translated onto the strings of the strat I was playing. Also the various amp models and lead tones mixed with synth tones and ambient sounds - wow! Jerry would have had a field day with this thing.
I recommend everyone give this thing a whirl and annoy the GC staff for a while, scroll through the bevy of stock tones - and when u get to the acoustic tones spend time in the editor, and mix with the guitar signal tone... It's really quite revolutionary.
