(Also, don't forget to turn your guitar all the way up to 10 on the guitar body. No reason not to send a loud signal.)
Great step-by-step from Greg, but I had to cringe when I got to this line.
Those knobs are there for a reason, and 10(or 11

) is not usually the best position.
More often than not, this can lead to some flatulence in the sound from the amp sim.
Your tone starts at the guitar, and it can have a dramatic effect on how a given preset in the amp sim responds.
You may find that many presets sound better with the guitar volume knobs set surprisingly low.
The cool thing is you can play with it while listening with input monitor turned on.
Like yellowcake, I tend to play the effect, so input monitor is essential.
Congrats on getting some free time (and some sleep

). Mine are all grown now, but I remember those days.
