Hi! I have an interesting device. I started working on drawing his schematic. Everything is clear. Give me time and I'll draw a diagram. If someone already has a scheme, we will cooperate.

Hi! I don't have the original, it is very expensive in Russia. But this device shows the basic meaning of the scheme. I modified the circuit for my needs by adding a more detailed simulation of the speakers and replaced the preamp. Many of the ideas of the schematic are original and proved to be very useful.
My dream is to draw a schematic of "origin effects revivaldrive compact", but this device costs even more, and copies are not being made yet.

The ly rock is a ripoff of the first batch.
I have changed a lot of stuff since then, but the structure is mostly the same.

Hi DSM, seeing a reply from you even "confirming" the copy is sad indeed ! Hopefully, this won't affect business much. Your pedal is an incredible and very pratical piece of gear !
Do you have any idea where they got the schematics and layout ? I have a Walrus Julianna clone of theirs, wanted to see how it was built, the layout looks like an exact copy of Walrus's. Obviously they could've just recreated it by reproducing the same exact layout, but I'm also thinkingna PCB manufacturer may have leaked it.

At first we thought it was a leak from the pcb fab. But there were some slight differences with our design. Probably it was a chinese distributor that we sent some samples from our first batch (that had some errors we had to correct by hand) . The pcb was probably x-rayed and traced. So far it has not affected us too much, and we know it's something that happens when a product is successful, so it was kind of flattering and disgusting at the same time. The chinese knockoff sometimes even works as a gateway for users to get our original stuff..the current version sounds much better than that old one, and the DLX is incredible (and the most complex thing I've ever designed).TheKoala wrote: ↑29 Jun 2022, 06:30 Hi DSM, seeing a reply from you even "confirming" the copy is sad indeed !

We try to keep launching new stuff as often as possible to keep up with rippofs, too. We have now the Silver linings, the clearcomp, and soon we will be launching another one.
It was a bit different with the omnicabsim tracing, since it was my only source of income and i was struggling, so it hurt more.

Saruman - I have a question about diodes in feedback loop of the first opamp. Are these LEDs with such low forward voltage? 0.7V is rather unusual for a LED. I'm not sure if I've seen a LED with Vf lower than 1.7V (more or less).

Thank you for the reply. So here's another one - on a drawing of a pcb there's a 3n3 cap - circled on a pic below. Looks like it's in series with 2k2.
Also, power tubes - what kind of a switch is this? on/off/on (in the unit that you traced)? I'm puzzled a little bit because order of the switching on the schematic does not match the enclosure.
Schematic - 6L6, EL34, KT88 vs enclosure - EL34, 6L6, KT88
