The Electro-Harmonix Operation Overlord is a stereo overdrive with serious range — from subtle grit to full-bodied drive that works equally well on guitar, bass, keys, and synths. Its flexible EQ and three-position input level switch make it one of EHX’s most versatile drives, designed to handle everything from vintage crunch to modern clarity.
 
Built tough and loaded with tone-shaping power, it’s a great choice for players who love experimenting or want one overdrive that can cover a lot of ground. This unit’s in lovely condition and comes with its original box.
