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.

some photos

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

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.
These photos were not taken by me, they are from the local local forum.

Small difference is in mixer (2 resistors) that's all.

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

Cheers.

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2) one of the transistors has been replaced by pedals from a rare series.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.

As I remember, I posted somethere Tonepad schematic with A.M. mods, about 5 or so yeras ago. Additionally one or two resistors at output mixers were slightly changed, that's all

Why is Analogman still held in such high regard by many? This, clean, build is pretty much the way stuff was built in 1985. That means that the man has not technically developed in over 35 years. It takes talent to be at such a standstill. A quick google already shows multiple sites selling pedal kits that are of the same or higher technical standard. And those are targeted at DIY-ers.

The empty parts are for a digital true bypass with some sort of microcontroller (PIC/ATmega).

@Dirk_Hendrik... I totally agree with you. The guy makes clones... as many people do around here

I think because it's a business. No doubt he knows a lot of stuff too, and how to make the pedals sound good. I mean we wouldn't have any of the stuff we have without good businessmen/women running the companies, such as Mike Matthews for example. I mean how many of the EHX pedals are just super basic circuits, sure there is more interesting designs, but many are clones too, and have been cloned. I don't particularly berate anyone for making products and selling them. A lot of people assign their own personal beliefs or elitism to whatever, who cares about all that, do what you love to do.
