I've tried several and never found one with even remotely the expression of a real guitar. I used a Boss GP10, which uses Roland's midi guitar tech, and low and behold I can play midi tracks on a real guitar, and everything I do for real, gets picked up as expression in the midi track. Added bonus, it also does real guitar and guitar effects and some variaxe type stuff like instant drop D tuning, virtual capo, and such.


Cheers,
