General Questions / Re: 1N34A germanium diode

BAT41 have a slightly higher forward voltage than 1n34a. You might try BAT46 instead.

General Questions / 1N34A germanium diode

Last post by garfo - March 07, 2026, 08:03:22 AM

I'm looking for a reliable 1N34A germanium diode replacement to use on the Low Rider analogue octave down project. I did some search and perhaps the BAT46 would work well on this design?

I am looking for something that is readily available.

General Questions / Re: Pearl Octaver and Boss OC-...

Both the Boss OC-2 and Pearl Octaver (Low Rider) have identical single Jfet input stages followed by an opamp gain stage.

The question is, are these single jfet inputs even necessary or are they a leftover from the original bypassing mechanism? It seems like the pedal should work exactly the same if the jfet stage was left out, or am I wrong?

Input buffers. They are usually skipped when building "replicas".

Right, that is what I thought but the Low Rider keeps this input stage.

Right around March 10th or sooner. I've also got restocks coming at the same time including all the VFE projects. There's another 10 or so projects that will drop soon after that, too.

Woohoo!!!

Update: the headers came today after all.

Dope! How about the coming soon stuff?

Well I have no choice except get them out ASAP (plus the other 10 that are basically ready) so I can work on the Microsynth. I'm gonna set a much better pace this year.

Looking forward to the microsynth!

Same - I will likely go for the Edgelord as an immediate follow-up.

Same, I have checked the "coming soon" tab for a hot minute awaiting both 'em.

Gate arrow is closer to source

So S connects to VR
Though orientation probably doesn't matter.

Thank you so much!!!

How's that microsynth looking?

I've taken a long time with it. Actually, just a week ago I found two mistakes (one critical) in my schematic. I will get the next prototype ordered and built in August. So, maybe September?

I might have shown this already but this is what we're looking at (for the 1790 enclosure). I have to change the bypass I/O to work with the new bypass boards but I think it is otherwise ready now.

Hiya Bean! Been a while. Hope all is well with you and yours.

I was searching the web for a "TAU PIPE" PHASER and wound up catching a glimpse of a MadBean "Synthwave" PCB in another forum. It got my curiosity peaked. What can you share about it or where can I lean more about it?

Thanks!
