Many things.
No Foldback. No Manual Tapering.
Key click filter installed.
Chorusing and vibrato are implemented differently.
Percussion implemented differently.

Here's a good place to start.

Ok Foldback have nothing to do whit the sound.

Manual Tapering what is that...

Foldback has everything to do with the sound. Do you know what that is?

is it not just A reparations of the keys or ??
if not then I don´t know what it is.
I have read about it but can´t find A explanation of what it dos to the sound only that u can move ex the deep C to the middle of the upper manual

Yeah and that doesn't change the sound?

is that A question for me.??
because I do not know what it does. Please explain it to me

Dude.... maybe there is a language barrier here but it's usually not best to ask for assistance then answer with "Ok Foldback have nothing to do whit the sound".
Usually, terse replies like that don't exactly foster cooperation.
Again, maybe a language thing but do try to propose/answer/ask questions in a polite manner. Might help?

So anyway...
Foldback is the re-use of TONES (every key can have 9 tones mixed in!) on certain keys, usually lower or upper keys
Which tones are assigned to each key and how MUCH of that tone is mixed in for that key DETERMINES the overall tone of that key.

They do this by using 9(tones) x 61(keys) = 549 resistive wires on a B3.

The raw tones that are assigned to each L or T keyboard is slightly different than a B3 (foldback)
A B3 may not have the same 9 raw tones as another model in the lowest octave.

The weighting/mixing of the tones that are assigned to each L or T keyboard is slightly different than a B3 (tapering)

In order to change the factory scheme of foldback and tapering for any organ can involve anywhere from 11 to 529 wire changes.

Each wire has a specifically chosen resistive value.

Politely chat with Brendon about how this can get very messy.

Best regards.

I think that it has to be something other than foldback because a M3 and Leslie sounds very close to a B3 and it doesn't have it. I have seen on you tube that if you add foldback to the M3 you can play left hand bass. This iis the only reason I can see for adding foldback to the M3. I once owned a T312 and with a external Leslie it came close to a B3. In my opinion, and I could be wrong, its all in the amplification. But if you want a spinet that sounds like a B3, get a M3.
