Micro Synthesizer

The EHX Micro Synthesizer is a fully analog guitar synthesizer. It can generate signals one octave above and below the original input signal, as well as a square wave at the frequency of the input. The mixed signals are then run through a slow attack effect and a swept resonant filter to produce tones reminiscent of analog keyboard synthesizers.
