I know this may sound ridiculous to many but if you are looking for one of the best all around guitar processors with all the Bells and Whistles plus a lot of stuff you might not use; check out the Fractal Audio Axe FX and the Digidesign Eleven. They are both rack effects processors with amp modeling, lots of presets and quite amazing algorithms. The sounds they can produce can be beyond my imagination. They are very expensive $1500-$2000, but if you want something to dream about, check out the sounds these units can give you on YouTube and their respective websites.
