1) I'll show this in the class.
2) Not really, no. For various reasons, you wouldn't really want there to be, either.
3) Not possible. The Axe will boot to the last preset selected. If you used it last without the MFC connected and you plug in the MFC, it will boot to the last preset the MFC remembers having been on.
4) Put the effects loop block first (so you get spillover) in all your presets' signal chains, plug the tuner input into the effects send but dont connect the return, and reprogram the tuner switch on the MFC to be the IA for FX LOOP.
There are tons of guys using the Axe for country, not the least of which being some of country music's biggest names. Once you start posting around, I'm sure they'll chime in! Welcome to the Fractal community!
