The Electro-Harmonix Bass Micro Synthesizer (Vintage, Made in USA) is a legendary analog pedal that turns your bass into a powerful, expressive instrument. It features four independent voices—clean bass, octave-up, sub-octave, and square wave—each with its own output control, allowing for deep and layered synth textures. A resonant 3-pole filter with adjustable start and stop frequencies, rate, resonance, attack delay, and trigger sensitivity enables sweeping, organic modulation effects. Housed in a robust large-format enclosure and handmade in the USA, this vintage unit reflects Electro-Harmonix’s pioneering spirit from the 1970s and remains highly sought after by tone connoisseurs and collectors.
Used by Colin Greenwood of Radiohead during their 2016–2018 tours and by Mike Gordon of Phish to add distinctive textures to his sound.
Please note: The Attack Delay slider is not functioning properly. It works when moved downward, but the sound cuts out when moved upward. All other functions work. No warranty.
