The DS-1 Distortion was introduced in 1978 as part of the second wave of compact pedal releases. Its hard-edged attack and smooth sustain was an instant success among guitarists, going on to fuel the signature sounds of numerous rock legends. The DS-1 has enjoyed such enduring popularity that’s it’s remained in the lineup to this day, outselling every other BOSS pedal to date.
Early Boss DS-1 units like this example featured the 7-pin inline Toshiba TA7136AP pre-amplifier rather than a standard dual op-amp. This chip gave the distortion a slightly warmer and richer sound compared to later revisions. Around 1984 Boss transitioned to standard dual op-amps (like the Rohm BA728N) because Toshiba stopped making the original pre-amp chips.
