have you heard the buzz about the Modeling discs for GNX's? You guys have to check out the Super Series discs. Unbelievable Sound!! I have Xedit and what you do is hook the GNX up and you have a Library of amps and patches. This is too cool !! I've never heard a modeler sound this good. Go to the sound community at Digitech and check it out. 1200 + files are on this disc ranging from custom modeling (acm files which you make your own presets..have to try this yet) to 400+ amp patches, 162 Artist patches and the sound is GREAT! This long timer at the Sound Community at Digitech made these they call him the "uber patch meister" .
