Sonic Oppressor

The Sonic Oppressor by Heavy Electronics is an optical compressor pedal designed to provide a wide range of compression effects. It features a full- wave rectifying circuit, which allows for greater depth and improved overall performance compared to half-wave circuits. The pedal includes controls for Output, Threshold, and Sustain. The Threshold knob adjusts the sensitivity of the opto circuit, while the Sustain knob controls the amount of signal boosted into the circuit. Additionally, there is a toggle switch labeled Gain, which introduces a significant fixed volume boost in front of the compression circuit, increasing both the compression and output level.

The action of the Sonic Oppressor is described as smooth and even, with no noticeable artifacts such as "dip and swell." The pedal is noted for providing extra thickness and punch to the sound, rather than precise control over peaks. It is recommended for users seeking to add color and thickness to their sound, and may not be suitable for those seeking clean, precise peak control.

The construction quality of the Sonic Oppressor is considered to be good, with a medium-sized housing similar to other pedals. It operates on a standard 9V DC power supply and features a true bypass footswitch. The pedal is designed to combine light and heavy-touch compression for a versatile range of effects.

The Sonic Oppressor has been praised for its ability to add thickness and punch without adding significant noise or causing loss of highs or lows. At low settings, the tone is mostly uncolored, while stronger settings introduce more flavor. Engaging the Gain switch can lead to overdrive, and the pedal is recommended for use with an amplifier that overdrives sweetly.

The Sonic Oppressor has been noted for its ability to provide a wide range of compression effects, making it a versatile tool for guitar and bass players. The pedal is available for purchase from various retailers and has received positive reviews for its performance and sound quality.
