Compressors are hard to pull off. Not to toot our own horn but we think we did. The Serpens is a very organic, and very touchy-feely optical compressor. It’s a must-have tool for tappity guitars if you’re playing math or midwest emo, for example. The controls are meant to be more intuitive than theoretical so you don’t need a college degree in sound engineering to operate the pedal.


The Serpens is a feed-forward LED-LDR optical compressor. It has tons of gain on tap and a couple of more subtle tweaks can be done under the hood through a pair of trim potentiometers.


Do not power with anything other than a center-negative 9VDC power supply. This pedal uses circuitry to double up the 9VDC power supply and you do not want to feed it any more. This kills the pedal and will void the warranty. You will be charged for repairs.
