So this is my second favorite thing I got for Christmas this year. My Atari Punk Console is embedded in an Altoids tin, but I have seen them encased in most everything. Plug your amp into the 1/4” socket and enjoy the digitized noise. Two knobs control the sound. You can find a premade version on Etsy and Ebay. If your handy with a soldering iron you can find kits at a number of places (here’s one).
The Altoids tin alone brings back memories. Man, you got a sweet nerd haul this year, didn’t ya?
