I GAS for the BOSS SY-200. It's the big brother of the SY-1 I have... and that thing has MIDI!That is cool. Of course you're right, but now it's affordable, and the tracking has improved. I say that having owned both a GR-700 and the smaller blue one, GR-500 I think?
So... in a nutshell I could convert a guitar to a MIDI guitar without having to install extra things on the guitar itself.
