The MXR Dyna Comp from 1979 is a true vintage classic and one of the most celebrated compressor pedals ever produced. Equipped with the highly sought-after LM3080N OTA (operational transconductance amplifier) chip, this unit delivers the signature smooth sustain and dynamic control that made the Dyna Comp a staple in countless rigs. With pot codes 1377951 and 1378002, this pedal is confirmed to date from late 1979 into early 1980, marking it as a desirable collector’s piece.
The layout is famously simple, featuring just two controls: Output and Sensitivity. Output adjusts the overall signal level, while Sensitivity sets the amount of compression, balancing sustain, attack, and punch. This straightforward design has made the Dyna Comp a favorite for players across genres, from the tight “squash” tones of funk and country to the warm, sustaining compression used in rock and pop.
Built in the USA with MXR’s rugged metal housing, these late-70s models are known for their reliability and tonal quality. The LM3080N-equipped versions in particular are prized by collectors and professional musicians alike, offering the pure, organic compression that defined an era and continues to inspire pedal builders today.
