Mesa Boogie “DynaPlex” Overdrive Pedal



DynaPlex™ goes straight to the heart of mid gain Brit, beyond Classic Crunch and ‘70s Rock sounds with a tactile feel and truly versatile, broad gain range.




Whether feeding on Single Coils or Humbuckers, the personality shines through in the most classic of ways with a ripping harmonic edge and cracking attack filled with attitude. A treasure trove of crunch rhythm awaits at the lower end of the Gain control, fatness and liquidity creep in just where you’d expect when gain is cranked for single note work, both keeping dynamic excitement front and center. 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. DynaPlex™ features a hidden EQ switch on the circuit board accessible from the bottom under the removable Lid that offers a more scooped, mid-dipped EQ curve. When engaged, this switch softens the Brit, mid-forward character of The Dynaplex for a leaner sound. 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, PRESENCE increases or decreases the overall brightness of the pedal, TONE 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.
