Here are some odd sounds I found while adding better controls to an Epiphone Headjammer (a little headphone amplifier for your guitar). I added higher pots and better switches, and now it just makes an assortment of fantastic noises and feedback squelches when there is no signal running through it. You can control the sounds with the pots and switches, but mainly by moving your hands around in the air above the Headjammer. I had to record this, just in case it doesn't happen again when I case the thing back up. Enjoy.
PS: This weekend I will post about turning my crappy Danelectro BLT Echo into a multi-speed delay pedal, as well as a standalone drone-machine. Stay Tuned!
