Hi,

I too struggled with this issue. I bought every sampled guitar library, even hired a session guy to play guitar.....that got expensive. One day a buddy of mine suggested I check out the following guitar library>

I watched the demos, after I picked my jaw off the floor, I purchased both the jazz and rock guitar library, I haven't looked back since. I can't recommend it enough, there is NO library or samples out there that can touch it, and the price is very low-$130!!!
VERY easy to use, tons of articulations and variations......

Bottom line, the realism of this library is scary!
