Mesa Boogie “Cleo” Overdrive Pedal



Cleo™ commands the lower end of the gain scale anchoring Blues, Roots, Indie Rock and even doubles as a hearty Boost, while it enhances, not covers up, the sound of your instrument.


SKU: FP.CLEO Category:


With sweet, open top end clarity and not too much saturation, it allows you to craft anything from a subtle boost up through urgent mid gain drive to harmonically-rich overdrive, all in the spirit of Tradition. Progressing along the gain spectrum, the transparent boost/overdrive CLEO™ is joined by the vintage-inspired, medium-gain DYNAPLEX™ and the higher-gain GOLD MINE™. Find your sound among these three new catalysts, combine them to create a new Tone all your own or keep them all on deck to cover the entire Ball Park of sounds you may need regardless of the Gig. Whichever path you take to enhancing your Tone, rest assured you’ve invested in quality and service unparalleled with a Brand that’s been around for a half century and will be there for you should you ever need assistance. Like each and every MESA product, these pedals are built using the same quality components and craftsmanship and are filled with the inspiring performance found in our custom amplifiers, all of which are hand-built in our only Shop in Petaluma California, USA—the Home of Tone®!


  • Controls: LEVEL is the master output level and it controls the amount of signal provided to the host amplifier, GAIN determines the amount of gain (overdrive) in the signal path, TONE This provides simple, global adjustment of the entire range of frequencies with one control, DIP SWITCH is a selectable EQ Voicing Switch located in the lower right edge of the bottom circuit board inside the unit under the Bottom Plate. Removing the Bottom allows access to this switch offering you two EQ curves. Select either a Mid-Scooped EQ response that excels at Rock Chording with the EQ ON setting (as Shipped) or a flatter, punchier, more equally balanced response that retains the Midrange frequencies and fills in the sound with the EQ OFF. The latter can be effective for single note soloing, especially at lower gain settings where you may want more focus, definition and body. Again, the unit is shipped set to the EQ ON/Mid-scooped position. Push the dip switch toward the Left to remove EQ circuitry and obtain midrange balance and a more even response.
