Launched in 1972, the MXR Dyna Comp was the original guitar-pedal compressor, and is still available from Jim Dunlop's revived MXR line.

"This pedal shows MXR got it right from the start when it comes to guitarists' needs"

This is the more expensive Custom Shop version as opposed to the standard M-102 Dyna Comp (£74), and is faithful to the 'script logo' original - with the same components, battery-power only and no LED.

This pedal shows MXR got it right from the start when it comes to guitarists' needs: it thickens tone and gets squishy if you need to, with a note attack that can have a pronounced snap but still sound natural.

Basic facilities for sure, but it does the job very nicely.
