Thanks guys. I read these posts and the GNX4 does it for me! I contacted Digitechs forum about the model packs and now I have them too. Wow is all I can say. The unit is good and some presets are okay but the model packs like others said here are what helps alot. Thanks for the reviews, all of you. I wasn't sure if this unit was above me or not but was surprised to find video tutorials on my disc from those packs. A very nice addition. Now I can play and play and not tweak all day! I 'm glad I spent some time reading and decided to go GNX4. This is too cool!
