Bass players unite. The iconic sound of the legendary Dyan Comp is now available for your pedalboard. No more settling for a circuit designed around guitar frequencies. Nope, this one's for you. Packed with features that deliver the most iconic compression sound in music history, this pedal features a classic "metal can" integrated circuit for quiet operation, superior transparency, and increased dynamic range. The star of the show here is the Clean control that lets you add in your unaffected bass signal, while the Tone control adjusts the upper midrange for increased clarity. Output and Sensitivity controls set volume level and sustain length while the Attack switch toggles between vintage-style slow attack and modern-style fast attack to fit your playing style. And it all fits in an MXR mini housing. So what are you waiting for?
