MXR Dyna Comp
MXR · pedal
The MXR Dyna Comp is one of the most iconic and recognizable guitar compressors, a colorful, character-rich pedal rather than a transparent one. Built on the Ross-derived OTA circuit with simple Output and Sensitivity controls, it behaves much like a limiter, taming pick-attack transients so the percussive pop levels out with the note while a long release adds body and sustain to fading notes. It rolls off some high harmonics and low end for a perceived midrange boost, giving it an unmistakable squash. It is a Nashville staple, its fast attack accentuating the pluck and cluck of chicken-picking and its sustain fattening pedal-steel-style bends, and it also underpins soaring solos in the David Gilmour vein. Beloved for its distinctive flavored squash, it suits country, funk, blues, and rock players who want a compressor with a strong, musical personality.
