One of my friends, Noel, playing the Garbuitar. He is a great guitarist and gave me feedback on what works and what doesn't. I had to rework the bridge after he played it, because simply tuning the guitar isn't enough - who knew? The guitar has to be intonated, which is a way of making all the strings have their halfway mark at the 12th fret. It was a pain, but now it works beautifully!
