The IC that came with it is a 4001.
The unit makes a clicking sound and the rate knob works, but it’s barely audible, and the tone switch does nothing.
What other component would be suspect if not the IC?

Hello John,
I’m not sure I can afford one of these, but if you’re willing to satisfy my curiosity, feel free to shoot me some details through private message.
Thanks,
Thomas

Looks fantastic!

Can the looper be restarted using a trigger or gate through one of the jacks?

I’ve always been a bit confused why all of the DRM series didn’t integrate a Clock-In. I suppose in 1980 it made the most sense to most consumers to use it as the master clock source, or forego syncing altogether. I’m surprised there isn’t anyone well known who provides this modification. The DRMs seem to sell pretty well on eBay and Reverb, so there has to be a market for it out there.
My DRM 15 has both clock in and out, which is great for syncing with the vintage 16 sec delay. I wish the DRM 32 also had clock in, but at least the clock out can be used in Eurorack with something like the Erica Synths MIDI to Clock module to convert the clock to MIDI.
Now that EHX is reissuing the Dirt Road Special, I wonder if they’ve thought about reissuing all of the DRMs, drum modules, and replays with updated sync options?

Amazing. As a proud owner of five vintage Dirt Road Specials, I’m really excited for an updated version with new features. I always thought 25 watts was loud, but using a tube Black Finger on the originals is almost mandatory to get any clean volume… but 50 watts will be great for plenty of headrrom.

There are really only a handful of EHX pedals with MIDI implementation. If I recall correctly, the first to include MIDI were the 16 Second Digital Delay RI, The H.O.G., and the 2880 Looper. Since then the trend has been to keep MIDI in the realm of loopers and the H.O.G. 2.

It’s possible that many guitarists ( who probably make up the majority of the market for EHX products ) have historically not been all that interested in MIDI. I don’t know, just speculating.

At any rate, EHX have always been pioneers with adding CV inputs to their pedals. I’ve always loved that about their products. I credit EHX for inspiring me to get into Eurorack synthesis, especially their vintage products like the DRM series, the drums, the Clockworks, the sequencers, and the replay samplers.

My recommendation is that you try to keep an eye out for a used Molten Voltage CTRL-Sync unit. It allows you to convert a MIDI clock signal into a tap signal. It works great on the Super Pulsar and the Deluxe Memory Tap Tempo series. It also allows you to divide or multiply the clock, which is super-useful.

Très cool, and tempting, but I’ve already blown my pedal budget this year on a vintage 16 second DD.
I see you are also selling your Attack Sustain. Have you ever done a comparison between the Attack Sustain and the original Attack Decay?
