I think I understand Squeak. When I first got Prosounds fretted module, I noticed that the Les Paul guitar sounds sounded like they might be ever so slightly out of tune, or maybe it was something else, but they sounded "imperfect". Yet when I play them together, it sounds just right, and it actually sounds a lot like my real Les Paul does, as opposed to some of the similar sounds from my Les Paul soundfonts. Perhaps the person who made it up uses at least somewhat of a similar setup to me with my Les.

The nuance thing and variation from player to player that Terry mentions rings true for me. I have an old Ibanez electric.. um I think it's a GX20 ? Anyway it's a low end model, probably in the 200 USd range, but it has a decent and distinct sound that works well for some rock tunes.

I recorded several notes and chords, turned them into wav files, and in turn made the wavs into a soundfont. It sounds exactly like "me" ( my pick, my strumming style, my amp, etc ) playing the guitar, only I play keys better than I play guitar, so I can do more musically with the soundfont than I can do on the actual guitar. I have better sounding commercial soundfonts to be sure, yet they don't sound as natural as my GX20 font when I play them.
