Electro Harmonix Sequencer Project Machine

“This listing is for a very rare Vintage Electro Harmonix Pedal. This is not a guitar pedal. It’s an analog drum sequencer. The pedal will also need some work and repair and is being sold AS-IS with the hope that someone out there has the know-how to fix it and use it properly.

This is the V2 later version of the Sequencer is from around 1980. According to online resources unit is 8-step sequencer, with Trigger In, Clock In, Clock Out, CV Out, Audio Out plus Clock/Pad slider switch for selecting either Pad control (piezo under leather front strip) or the Clock source. This sequencer can be used with the Electro Harmonix DRM32, DRM16 and DRM15 drum effects.

I’m in no means an expert on these. I did a basic test of this and it is making some “video game” noises but I’m not even sure exactly how to use it correctly. The Clock-Pad Switch is missing a screw and is broken and there is something rattling around inside the unit. One of the slider switches is broken. The original slider tip is included but would have to professionally repaired.

As I mentioned before, this unit is being sold AS-IS and will certainly need some repair and restoration. This is one on of the rarest Electro Harmonix effect units. ”

Electro Harmonix EH-400


This synth is needed for any Electro-Harmonix collection. A monophonic synth, very similar to the micro synth except with a playable tone generator. It is very good for bass, even with its single oscillator it has that Moog Taurus sound.

This one is beat up because they were fragile units, much like the EDP Wasp. But, it is still fully functional. There are two cracks on the sides of the plastic housing but it feels pretty solid. Some of the sliders are a little crackly (noisy) when moved. There have been various repairs on the unit so it is now in good working shape.

Also, it is missing it’s speaker, so you’ll need to use the audio output.”
