Attached are photos of the last three guitars. Number 3 is pretty straight forward, without any special effects. It sound great and is fun to play.
Number four is a bit crazy. I made this from an old Hershey's Pretzel tin I used to store small electic parts for hotrods, back in the day when I was still building them. It too sounds great, and has a bit of a banjo feel to it.
Five is the fun one. It's my 'redneck' complete with the appropriate decoration. I set it up without frets, which requires the use of a slide.
All the guitars can be played acoustically or through my amp, and they do sound very good for being constructed from cigar boxes or other unusual things.
