Yeah, a "scene" is like a page of presets kind of. The pedal has 12 switches, and you can store 12 scenes on it.
Essentially it means that under each of the 12 switches you can store an effect, but then under each of those you can also store a "scene" that takes you to a whole other 12 effects. I don't think I'm explaining this very well, but it's basically got 12 effects, but you can program 12 different sets or pages or scenes. So like if I want to play a blues song, I'll turn on my blues scene, which will have 12 effects that I set for playing blues music. I'm looking to make one for playing DT songs where I would have 12 pedals devoted to DT-like sounds. Choruses, Overdrives....the works.
It's a really cool pedal actually. I've never been a fan of the all-in-one pedals, but this one is different. Love it.
