Compulator Pro

The Demeter COMP-2 Compulator Pro is a high-quality optical compressor pedal that provides the magical sound of LA-2A type compression in a compact and powerful package. It features the same circuitry as the classic Compulator pedal and adds attack and release controls, allowing users to modify the onset and sustain of the compressor. The pedal enables users to finely tune their compressed tone to mimic almost any type of compressor. Additionally, it includes an adjustable gain boost for deep compression at the flip of a switch and can be set up for two different instruments. The pedal is hand-made in the USA using the highest quality components and is housed in a rugged steel stomp box with heavy-duty hardware. It also features true bypass using an ALCO heavy-duty foot-switch and can be powered via a 9V battery or external power supply. The dimensions of the pedal are approximately 4.75 x 3.75 x 2.25 inches (121 x 95 x 57mm).


The Compulator by Demeter is a pro-level optical compressor designed to deliver classic studio optical compression of the 60s and 70s in a compact stomp box form factor. It is known for providing even levels and bright, punchy gain without compromising the original tone. The unit features two controls: compress and volume, along with a foot switch to bypass the effect and an LED to indicate effect operation. Additionally, there is a trim pot to set the overall gain of the unit, and the compress knob offers up to 30dB of gain reduction. The volume knob adjusts the output volume of the Compulator, allowing for level matching between the affected and unaffected signal. The unit is powered by a 9-volt DC supply, which can be either external or internal using a 9-volt battery. The steel enclosure and heavy-duty hardware make the Compulator a rugged and durable unit suitable for both studio and live performance environments.

The pedal features a Compress knob to control the amount of gain reduction up to 30dB, a Volume knob to adjust the output volume (makeup gain), and a Trim Pot for adjusting the unit's preamp gain to avoid distortion when using a hot instrument input. It is powered by a 9-volt battery and also has a standard 9V jack for power. The street price for the Demeter COMP-1 Opto Compulator is generally around $199.00.
