This is a project I've been messing around with. It lets you really open up the possibilities of your FBV3 and /or FBV shortboard MkII. It allows for full color functionality of FBV3 as well. It requires some basic know-how with an Arduino at present, though with very little effort on Line 6's part, that may not be necessary in the future. Check it out:
