Cool idea! I kinda made the same thing long ago but it actually used my amps with a mixer circuit going to headphones. This is a LOT more convenient!
It's kinda sad that they had to make 3 different models (well, probably not for their sales) though. It would be great if you could get one that could select between the different sound profiles.
Someone mentioned a bass model coming out soon, that's what I'm interested in. Anyone know whether there will be different models of that for different sound profiles?
Edit: OK, I guess I found the answer, apparently, there are 5 models, only one for bass:

I have NO idea what to do with those skinny stringed things... I'm just a bass player...
