Constructed with a three-knob interface consisting of controls for sustain, level, and attack, a low noise floor, and a nuanced presence that complements rather than consumes your tone, the Joyo Dyna Compressor is a vintage effect in a modern world. Designed to emulate the famed Ross analog comps from the 1980s, Joyo's rendition gives a subtle flavoring to your sound that even the most ardent of anti-pedal proponents can get behind.
