He took a classic photograph of the CMS detector - a head-on view showing the detector's "interaction" point where the protons collide - and had it imprinted on a 600-piece jigsaw puzzle.
Then he put the puzzle together, and "cut out" the pieces he wanted to be on the face of the guitar. He attached them piece by piece and finished it off with a nice clear coat lacquer.
Tracyk also incorporated a couple of pixel detector prototypes, a tin surface divided into around 4000 readout "pixels" to detect particle tracks from the collisions, into the guitar volume knob. And he only kept the first five frets, since he was intrigued by the notion of a fretless guitar.
You can check out the finished product in the video below, of Tracyk's performance with his band, Miss Proper and the Moving Target, at the 2012 CERN Hardronic Festival. He knocked out a killer rendition of ZZ Top's "Sharp-Dressed Man," thereby demonstrating that particle physicists can rock out with the best of them.
