Radical Frequencies SH-1 / SH-7 filter clone
Radical Frequencies SH VCF It is a complete discrete through hole replica of the the original mono synth sh-1 filter from late 70s ! In detail it is a cascaded OTA low pass filter with four OTA-stages of the original vintage CA3080 ics with FET transistors as Buffers , it has 2 inputs with potentiometer , 1 cv input with potentiometer and 4 independent low pass outputs one for every ota stage : 6db , 12db , 18db and ofcourse 24db. The 6db and 12db outputs are in 180° phase , as result you can mix them together with 24db out in a mixer to make bandpass and hig pass combinations !
In order to achieve a clean sound the input level must not be over 70% to 80% but if you boost the input you take a wonderful saturation that if it's combined with a lot of resonance the result is magic especially from the 6db out ! Of course the 24 db out is perfect for rubber and punchy basses like the classic vintage Japanese synths
