This Heavy Electronics Sonic Oppressor Compression pedal offers a perfect range of subtle compression to full-on squish. The goal with the Sonic Oppressor was to create a pedal capable of producing delicate compression but could also offer significant peak reduction and smash, all while staying completely usable on everything in between. Part of the magic is the use of a full-wave rectifying circuit (rather than half-wave) that allows for greater depth and improves over-all performance on more frequencies. Plus, it's super quiet thanks to the high quality Burr Brown Op-Amp.

The control layout is simple and intuitive, with plenty of headroom on tap from the Output control. The Threshold and Sustain controls work in tandem to define the response. The Gain switch adds significant boost to the circuit allowing the Sustain knob to push well into overdrive territory, if you're so inclined. And what's really cool is the LED in the middle of the eye decal—it's tied directly to the optical circuit and shows exactly when the notes you play are triggering compression. This Heavy Electronics Sonic Oppressor Compression is a super smooth, no-compromise pedal that offers a plethora of tones for stage, studio, or home.
