This vintage (model IC100L, or 212, or V-S MUSICIAN, or all ?) solid state combo amp is one of the best sounding guitar amps what I ever heard, with rich creamy sound and powerful.
I found some schematic, but is not clear which model, I am not sure. There I saw some specific chip used for simulation of "valve sound": V-S MUSICIAN Tone correction module AS00015/A. That is IC, or just module with separated PCB?
If this is the module with PCB, please if some of you have a schematic?
Also whether is this schematic of amp about I talk? If its not, please I need right complete schematic.
Thanks in forward!

You have all the schematic of the VS-Musician lead guitar amp. The Tone correction module was sealed and the circuit was never published.
These were incredibly loud amps although only rated at 80 watts into. 8 ohm and 100 watts into 4 ohm. More details are available from 74 Series, Other Transistor items in MAJ Electronic store on eBay!.

Sorry that was an error and I have only just noticed it. The real link is http://www.majelectronic.co.uk

Even better:
But as I said, nothing too weird, just a simple FET gain stage.
One trick is that they feed it with meager 10V, single supply, so it clips earlier, they limit its headroom this way.
Gallien Krueger Bass amps have something very similar, they call it GIVE (Gate Induced Valve Effect).
Not too different from what an overdriven12AX7 would do.
