This is my home made buss compressor. I built it about ten years ago (when I had a lot more time), based.on the gyraf GSSL clone project. I had no case so it lived in a shoe box for a while, then got built into the case of a broken XBox my brother was throwing out. The meter is off an old fighter plane, an eBay find. It has some quirks but it sounds great and good to have it back in service.
