1978 Boss DS-1 Distortion Silver Screw Long Dash Vintage Guitar Effects Pedal, Japan


+ shipping

Up for sale, a 1978 Boss DS-1 Distortion “Silver Screw” effects pedal in perfect working order. The DS-1 Distortion is a true icon in the world of guitar effects, utilized by artists from Kurt Cobain to Robert Smith to Glenn Frey and back. This pedal was made during the first year of DS-1 production, retaining the desirable silver screw for the battery compartment, only seen on the earliest examples. Boss’ first distortion pedal defined a bold new sound, delivering hard-edged attack and smooth sustain that’s been a staple for generations. And this Japanese-made black label iteration has a notably thicker, smoother, and more dynamic tone than later iterations. The circuit is untouched with the original Toshiba TA7136AP pre-amplifier.

There are a fair number of scuffs and dings on the enclosure, as well as an “Austin Reed of London” sticker adjacent to the input jack. The pedal retains the original trio of knobs, Japanese black foil label on the back, and stamped black ink serial number in the battery compartment which dates it to December, 1978.
