One of my favorite parts of David Ellis’ work is his integration of sound into the pieces.  I can only imagine about the extent to which this is accomplished with his SKDubs gold (double bass boombox fiddle).  The material list in making this 36 x 50 1/2 x 17″ piece is insane.

Medium-modified double bass fiddle, spraypaint, casters, oak, plywood, metal, iPod, two tube pre-amps, B and C mids and tweeters, Electro-voice woofers, JVC tweeters, Crown XLS 602 Poweramp, and Behringer equalizer.

The man knows what he is doing.  Edition of 3, 2005.  $15,000.  Available through his website
