just a couple of questions for anyone who has one:

1. can it be used to switch between distortion and clean seetings if they are programmed into it??
2. can the expression pedal be used a a wah pedal??
3. could i be set up just: guitar -> tonelab le -> PA ??

1. Yes
2. Yes
3. Yes

It will still sound like a digital modeler though. It's better than some, but IMO the versatility isn't a good enough trade off for sounding like a digital modeler.
