... I really love guitar (electric, acoustic and bass) but it's one of those sounds that is hard to immitate (not impossible, but to do it correctly on keyboard you have to have so much knowledge of the playing style of those musicians and you have to spend so much work on getting it to sound natural that I mostly give up). I've gotten myself a cheap guitar though and I'm learning a few simple things so my aim is to combine simulation and some real play into what hopefully sounds convincing or at least interesting. Still, a real guitarist can add so much more...
This one, to my ear, is perfect.
There is a charm to the synthetic guitar - very percussive, characterful and uncomplicated. The production of the song is as much an artistic statement as the music itself, and deserves to be enjoyed in its own right.
Bottom line: don't mess with it, friend, you have a winner here...
