Okay look. I'm all for people using extended range instruments and all that good stuff, but why the hell does this guy really need 24 strings? Listening to his composition thing I didn't once hear the super low strings and nothing way up top, so why? Obviously this isn't the only song playable on the instrument and I'm sure there's more uses for this, but it just seems like an attention grabber. If you have all those strings then show me you can use them!
Dude did make this at home though, which is cool.
