This is a simple, but effective optical compressor. The kit itself is very straight forwards. As you can see, the PCB is small and well laid out.
This particular listing is for the kit to come with a JP1590B enclosure, the newly laid out PCB now hangs from both pots inside the case.
Whilst the build guide images have not changed from the older layout, the circuit is identical and the build principle identical.
This kit compares to the Flatline Compressor.
