The MXR M291 Dyna Comp Mini Compressor Pedal delivers the iconic squish and sustain of the classic Dyna Comp in a smaller, pedalboard-friendly package. Featuring the same OTA (operational transconductance amplifier) design that defined countless legendary guitar tones, this compact compressor adds the Clean and Tone controls from the larger Custom Comp Deluxe for even more flexibility. Use the Clean knob to blend your dry signal back in for natural dynamics, while the Tone control lets you fine-tune the high-end response. Perfect for both subtle smoothing and tight country-style compression, the M291 maintains your guitar’s clarity while enhancing sustain and punch.
