I took a quick look and Bourns makes rotary encoders without detents that seem like they would be perfect for this, and they are cheap.
Similarly the code needed to detect the changes is not difficult, though if you want them to feel nice (rather than require a lot of turns) you may want to apply some acceleration curve to them which is a bit more math.
I think "cheap" is not exactly an objection when it comes to Amp X.
However, it seems to be cast in stone that it'll feature non-endless encoders - and as far as that nonsense goes (there's no justfication for standard 270° encoders in the digital world anymore), I'm defenitely not one of BluGuitars customers, regardless of how great this thing will sound.

Interestingly enough, even if it might read as an oxymoron: To get as close to analog usability in the programmable world, analog-style pots are completely counterproductive.
"Select something -> perhaps (visually) check current parameter value -> adjust". That's the closest you can get in digital land.
"Select something -> try to find out about the current parameter values in whatever weird ways -> adjust" however is bogus. But it's precisely what you get with analog-style knobs.
