The OKKO FX Cocaine is a compressor pedal built around an optical compressor circuit, which the maker describes as an "addictive compressor / eq / preamp / boost". OKKO FX says it is transparent, natural sounding and exceptionally quiet, and that it makes instruments sound more balanced and sit better in the mix1. It belongs to the broader family of compressor pedals, with a boost circuit and preamp function built in.
What it does
The Cocaine is an optical compressor, a design that uses a light-dependent element to control gain, which the maker describes as exceptionally quiet. OKKO FX says it adds clean, undistorted sustain to your tone through its SUSTAIN knob, and that it works with whatever you plug in: electric guitar or bass, piezo-equipped acoustic guitar, or any other stringed instrument1.
The pedal is a bigger version of the maker's two-knob COCA Compressor. OKKO FX states the Cocaine features the same optical compressor circuit as "its little two-knob brother, the much beloved COCA COMPRESSOR"1.
The voltage doubler and the boost circuit
Two features set the Cocaine apart from the simpler COCA Compressor:
- Internal voltage doubler: OKKO FX says the Cocaine features an internal voltage doubler for increased headroom and superior dynamic performance1.
- Independent boost circuit: The boost is activated by its own footswitch, separate from the compressor1.

Questions
Is the OKKO FX Cocaine the same circuit as the Coca Compressor?
Yes. OKKO FX states the Cocaine features the same optical compressor circuit as the COCA Compressor, which the maker describes as its two-knob brother. The Cocaine adds to that circuit with an internal voltage doubler for increased headroom and superior dynamic performance, plus an independent boost circuit on its own footswitch.
Can the OKKO FX Cocaine be used with bass?
Yes. The maker says whatever you plug in works, naming electric guitar or bass, piezo-equipped acoustic guitar, or any other stringed instrument. The pedal is described as transparent and natural sounding, and as making instruments sound more balanced and sit better in the mix.
Does the OKKO FX Cocaine work with a piezo acoustic guitar?
Yes. OKKO FX names piezo-equipped acoustic guitars, along with electric guitar, bass and any other stringed instrument, as suitable inputs for the Cocaine. The maker describes the optical compressor as transparent, natural sounding and exceptionally quiet.
What does the voltage doubler do in the Cocaine?
The Cocaine has an internal voltage doubler, which OKKO FX says provides increased headroom and superior dynamic performance. More headroom means the circuit has more room before the signal is compressed or colored in an unwanted way, which matters when playing harder or with hotter pickups.
How much does the OKKO FX Cocaine cost?
The maker's product page lists the Cocaine at 209.24 euros, excluding shipping, as of 26 October 2026.
