With the Lumberjack, Electro-Harmonix took the premise of an overdrive and turned it on its head. Or, more precisely, bent it out of shape. Whereas overdrives traditionally operate on a linear scale, the Lumberjack functions on logarithmic equation in order to create your effect. Featuring only Volume, Boost, and Log Factor (amount of logarithmic amplification) knobs, this pedal is capable of boost, overdrive, and fuzz/distortion, navigating each deftly. After getting a sense of the pedal, switching from boost to overdrive to distortion to fuzz is as easy as a few quick turns. This pedal is in good shape with minimal cosmetic wear and functions as it should. Original box not included.
