This doesn't look safe to build for most DIYers, but I see from videos on YouTube a few people have tried this before. It sounds a little harsh, with distortion a bit beyond a heavy metal sound, but the Digi-Key setup sounds better than most. I wonder if you could use a tube amplifier somewhere in the circuit for a smoother sound.... If it didn't sound better, at least it would look even more extreme with the lights off.

Tesla Coil Guitar Amplifier
High voltage is not just the name of a song and album from AC/DC. The latest Another Geek Moment Video from Digi-Key shows how to use a Tesla coil to see and hear "high voltage rock and roll" without an amp or speaker.

Audio Kits and Amplifier Boards
Parts Express has a great selection of DIY parts for audio projects as well as A/V cables and equipment. They have recently added a DIY kits section to the website. Most of the products are called kits but I would call most of them boards because come fully assembled and tested. They stock Velleman and Parts Express brands. You can find a lot of audio applications including AM/FM radio, MP3 player, and a few Class-D audio amplification boards. The amplifier boards use Tripath, Texas Instruments and Power Analog Microelectronics chips. For an example see the video below for the TK2050 Class-D Audio Amplifier Board. It is one of the higher end kits at $44 US, they start at $9.90 for the 2x2W@4 Ohm Class-D.

Jameco Electronics always has a good selection of audio kits and kits in general. Here is an example of a guitar effects pedal built using the Perfboard Prototyping Kit.
