me too, i roll back to 1.72 with the old acoustic sounds and i tweak the eqÂ´s on the fx-rack higher(presence!). the guitar works good for me.
i think a softwareupdate is a good thing, if there were huge improvement, but you listen to the comparison of v1.9 vs 2.0 and v 1.9 to old v500, the difference is not very big.
Cause everytime you change your settings (update) youÂ´ll have to change (tweak) your sounds to your personal taste, and in the end itÂ´s more an "tweaking" than an guitarplaying!
i always say: never change a winning system - donÂ´t tweak to much --> play your guitar (itÂ´s all in your fingers)
