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. It comprises four parts: a six-pole, thin pickup which picks up all six strings separately, the converter, which is also the control unit, a small junction box with a MIDI output socket, and an external power supply which provides the low voltage to drive the system. The pickup attaches to the guitar as close to the bridge as possible, while the convert is fixed via the strap peg on the end of the guitar body. Using a pitchtracking system, the convertor unit processes the output from each section of the pickup, extracts the fundamental pitch from the harmonics and then converts the pitch to MIDI information. The SH-075 sold for £350 but you needed to combine it with a synthesizer - Shadow sold an SH22 unit for £325 - making this the most affordable guitar synthesizer setup at the time.
