You never "lose" a level up--you can always reset songs to the highest difficulty achieved with a press of a but.ton in Options.
Ah, I didn't even go look. They must have some built in processing. There was a thread on this forum about guitars with built-in processing. I don't remember if the Line 6 was mentioned or not.
I'm all for tech stuff, and I used to be big into multi-fx and simulated amp/speaker cabinets. I just some how never liked the idea of it all in a guitar. Kinda like I never liked the idea of a TV with a built-in VCR (blu-ray today?) . Now a modern TV with all the built-in streaming protocols, that is a good thing, that won't have one part biting the dust before the other. I don't think there is an equivalent for the guitar, except maybe MIDI or D/A converters built-in.
I hate hipsters. Their smug faces, vegan diet, tiny feet and sawdust bedding. No wait. Hamsters. I hate hamsters.

Want to level down a song? Try playing Chimney after you haven't played it for 3 months. I just quit after a few measures. Some songs you just have to play sober.
