Amdek OCK‑100 is an early‑1980s octave‑down pedal kit from Roland’s Amdek DIY series, designed to produce a thick, synth‑like sub‑octave similar to the Boss OC‑2 of the same era. It uses analog divider circuitry, giving it a warm, slightly glitchy tracking character that’s very “vintage Roland.” Because each unit was hand‑assembled from a kit, build quality varies, making clean, well‑built examples rare and collectible today.
