Flatline Optical Compressor

Description

This is an optical compressor based on the John Hollis Flatline Circuit.  This pedal was built on the the Afterlife circuit board sold by Madbeanpedals.com.  The pedal contains an Xvive VTL5C3 Optocoupler.  The following is the description of the pedal from Madbeanpedals:
"The Afterlife compressor is based on the John Hollis Flatline. It is a low-parts count, optical
compressor that will add excellent sustain and compression to your guitar tone. A simple op- amp gain
stage at the signal input sets the compression amount. The dynamic level of the input is processed
through IC1B where the signal is then rectified to drive an LED. The LED is the “engine” that drives
the photocell in parallel with R3 which dynamically changes the overall gain of IC1A. The end result
is that your guitar signal is compressed so that the overall dynamic level is evened out, thus creating
sustain."
