Shadow SH-075 guitar to midi convertor

in the mid 1980s synthesizer music was hugely popular - think Harold Faltermeyer's Roland Jupiter-8 driven  "Axel F". This drove a period of innovation for dedicated guitar based synth controllers, like Synthaxe and Stepp - but also guitar to midi convertors like this Shadow SH-075. The SH-075 is a quick mount guitar-to-midi convertor - deisgned to attach to an electric guitar.
