It's pretty simple to use, as long as you know what each of the units is. I love this program since I love trying to match a guitar sound exactly as I hear it in a song, so all the gear in here has made it really easy to do. There's so much stuff in here- a ton of amp heads and a ton of cabinets, plus loads of classic effects pedals (Boss DS-1, Tube Screamer, Big Muff, Boss CE-1, etc).
