I've compared the originally posted schematic to an actual unit, and have updated it to reflect what I've found inside my unit. Here is the verified schematic for the 2001 (version 4) of the Expandora;

I'm working on the 2000R (version 3, Godlyke reissue) at the moment. It does not use 308's, but a single 072 instead. Once I'm done, I'll post the schematic.

The only issue that will be MIA will be the very first version, commonly know as the "Script" version. This was the very first Expandora;

From what I can gather, it was fixed gain in the feedback loop (read "boring"). Unless someone has one, and wishes to share, I'm not bothering to chase this one.

Thanks to Digi2t for sending me his 2000R version 3 Godlyke reissue schem. It's the one with the 3 external switches, not the Expandora II, which is the main subject of this thread. Here it is re- uploaded.



The difference I was most interested in is that guitar/bass voicing switch at the end. I modded the values on my Sabro v1 clone layout to match it.
