1982 Boss SD-1 Super Overdrive Guitar Effects Pedal Black Label Japan w/ JRC4558D Chip

Up for sale, a 1982 Boss SD-1 Super Overdrive effects pedal in 100% original condition and in perfect working order. The SD-1 Super Overdrive produces the warm, natural distortion of an overdriven tube amplifier while maintaining the subtle nuances of a player's picking technique. This is one of Boss’ more responsive, dynamic, and smooth-sounding overdrives and also one of its earliest pedals, perfect for classic, natural tube-like growl. Controls include Level, Drive, and Tone.At the heart of this early version of the SD-1 is the same JRC4558D chip used to create the classic textures of the Ibanez TS-808 Tube Screamer. In the SD-1 circuit, the chip offers a more balanced midrange and more grit.This classic overdrive retains its original silkscreen graphics and shows its fair share of nicks and scuffs on the edges of the enclosure, with stock knobs and original black "Made in Japan" foil label on the back. The white serial sticker is also present in the battery compartment.
