I recently borrowed a friend's GT-8 for one night. I didn't have a chance to run it through an amp, but I used headphones and went through the manual and messed with just about all the settings. The only things I liked were the effects that didn't use some type of distortion. It does those things well, but as far as the preamp stuff and distortion, no way. I still really want to try it through an amp, but so far, I would not use the GT-8 for direct recording.
