General Guitar Gadgets is the best DIY stompbox site on the internet! We feature projects, kits and ready-to-solder PCBs.

This is the Dan Armstrong^™ Orange Squeezer^™ replica, known as OSQ.  It is an excellent little compressor and easy to build too. The original unit plugged directly into your guitar. We have updated this to standard stompbox format.
