Looks like this is correct – there is definitely a 3rd version with the clock out and bass out.

Cool, I appreciate the offer, but I’m really only collecting the EHX drums that have some sort of clock or trigger.

So far I have

Super Space Drum
Drum Sequencer v2 (with Clock and CV out)
DRM-15

and the non-vintage Clockworks and 8-Step.

I emailed Julia about the Space Drum and Sequencer – both have minor issues – and she is repairing them for me. Saves me the increased odds of wrecking collectible gear if I were to do it myself.

I think I got the Crash Pad schematic from you this weekend – I’m dangerous with a soldering iron, but I’m going to attempt to get the parts and try and breadboard it for now, maybe get a PCB made if I can come close to getting it to work!

I also sent an email to you through the EHX history site regarding manuals for any of the drums, especially the ones listed above. I would pay for soft/hard copies of any of the manuals. I asked Julia, but she doesn’t have them and suggested asking the EHX man!

No, I don’t think she normally repairs pedals. I asked her that same question via freestompboxes.org, where there are several posts regarding the pedals she created, including schematics, and I think she was initially reluctant, but agreed to look at them after a few emails. You can ask her, but your mileage may vary. If not, the EH man might be able to recommend someone.
