Jasper is a DIY clone of the EDP Wasp synthesiser from the late 1970s and early 1980s.
Jasper started as a personal project to build a working copy of the Wasp – and was offered as a limited PCB run on the Muffwiggler DIY synth forum, back in late 2015. The original forum post has grown into a massive thread, and has lead to four PCB runs so far. The build thread’s first post currently has the build guide and other information. I’m amazed at the enthusiasm people have shown.
Jasper is only offered as a partial kit – comprising of a printed circuit board, a control panel made from PCB material and the harder to find components. It is not an exact clone – in that some component changes have been made to make it work with transistors and ICs currently available – and a few extra features have been added for convenience. You need to build an enclosure or case for it as well as soldering all the components.
This site will host information about Jasper and its associated projects, including the build documentation and tips, and I hope to highlight some of the builds people have made with my PCBs.
