USED BOSS / OD-1 Overdrive Raytheon RC3403ADB BOSS Effects Pedal Overdrive [10]

A legendary pedal that pioneered the history of overdrive—a rare early-model OD-1!
A 1979 BOSS OD-1 Overdrive has arrived.

This legendary early model from the BOSS Compact Series established the new genre of overdrive and had a profound influence on subsequent drive pedals. This unit is an early-production model with serial number #8300, featuring silver screws, a green circuit board, a skeleton switch, and a Raytheon RC3403ADB quad op-amp.

The controls feature a simple layout with only LEVEL and OVER DRIVE, and it is powered by an AC adapter. It still retains the original back cover screws and lock washers—parts that are often missing—making it an excellent reference piece for vintage collectors.
While the frequency response is concentrated in the midrange, the distortion has a very smooth texture. It combines a lustrous, violin-like quality with crystal-clear transparency, producing a smooth, singing drive sound.

The LED indicator is dedicated solely to the battery checker and, unlike current BOSS effects pedals, does not remain lit at all times.
An old sticker marked “10717” is affixed to the upper side of the enclosure. While the date it was applied and its purpose are unknown, it is one of the features that evokes the long history this unit has endured.

This unit preserves the unique sound and rare details characteristic of the early OD-1 models. It is highly recommended not only for players but also for anyone seeking a vintage BOSS pedal. Please take advantage of this opportunity to purchase it!
