Flatline mods!!!

[psyche]

Hi there,

My name is Padelis and i am from Greece.I built yesterday the flatline compressor and i used a pc817 optocoupler instead of a led/ldr!!!!The problem is that the compressor sounds a little like an od pedal!!!!I am trying different resistors in the place of the 220k.I am trying lower values and now i am testing a 100k resistor.The gain lowers but the distortion doesn't go away.there is still a little od.Also i am using oa90 diodes.
