@Greg Ferguson will not steer you wrong nor will many others around there.
3. An EV PXM-12mp will get the job done. It's a beast. Use monitor 2 setting for best results.
4. Remember that you hearing a mic'd cabinet. It may sound thin at first, but it'll be great through a P.A. and band mix when you get the volume cranked up. If you get too thick of tone from the start, it'll probably be muddy and not cut in the band mix.

6. Add some parameters to the "Performance Page" so you can tweak easily at a gig.
7. Maybe try a digital delay at 7-10ms to thicken up your guitar if you're the only guitarist.
