Simple AXE FX question: What is your signal path?

[cg]

What is your signal path from your guitar to the speaker? Which power amp, speaker cab, etc?

Please don't stray from this question. Keep the pro and con arguments on other threads.

I am curious about the unit and how people are using it. It sounds like there quite a few variations out there.

I'm sure this info is spread throughout countless threads, but I thought it would be useful to consolidate it here.

Thanks!
