A.M. chorus 97% == tonepad small clone, except 2-3 values
Hi
I'm aware, but I have not found any exact changes anywhere.
Once you decide to stop releasing your chorus, maybe you'll share the differences in the components?
In this thread or in private messages.
I have a couple of assumptions about ceramic capacitors (1 changed value, 1 is missing in the circuit), but this is only an assumption.

The thread title shows "Traced", did I miss something? :scratch:

I would say, make the tonepad and mod it to an am C ... should do the trick :p

Right, I get that but did we ever figure out what the changes and values were?

Not
There is no reliable scheme anywhere.

i re-drawed schematic of analog man chorus (s/n ~3000), it's almost 99.9% Tonepad Small Clone , including Depth Pot , and Depth Switch idea.
Small difference is in mixer (2 resistors) that's all.

"legend is more important, than music", that's all about analog man, cap.

Cheers.

we've traced several years ago.

gena_p1 developed by one of the Russian boutique companies, they previously sold a modified clone of this chorus, but they didn’t open the scheme on any other sites even after the cessation of sales, simply ignoring all messages.

The following differences are mentioned at different sites.
1) the capacitor 150p is replaced by 100p.
2) one of the transistors has been replaced by pedals from a rare series. Of course, the transistors working as buffers in this circuit (2 in the filter and one in the clock) will not change the sound much, most likely we will not notice this at all, but if we change the pnp transistor in the first filter to npn and add a resistor to the emitter, then we get a completely different filtering.
