That happen when the analyser can't fetch any influence of a variable resistor. Bu, I tried your circuit from above and get it working as expected. For reference I've attached...

For the fun I made quickly the power amp stage of the Voxac30: [voxac30_poweramp.sch.tar.gz](https://github.com/brummer10/guitarix/files/8685085/voxac30_poweramp.sch.tar.gz) It should replace the stage_03. I build a guitarix plugin from it by: `./build-plug.py -i voxac30_poweramp.sch...

To make a controller logarithmic, you must add `,a=3` to the value field. were the value (3 - 9) sets the logarithmic scale. I'll check my schematic folders to find...

Here they are: [plexi-schematics.tar.gz](https://github.com/brummer10/guitarix/files/8692243/plexi-schematics.tar.gz)

This is the right place here, and I'm open to answer all questions about it (and fetch your input). At least we make it open source for that reason. Documentation...

That's why I said your input is welcome. I wont said this tool is perfect, the opposite is the case. So, when ever you've a idea to make it better,...

Beside that, I guess you are aware that I've developed a couple of plugs already with this tool, were I work around the drawbacks it has. Still, some academical research...

That may be relate to the windings or the resistance of the transformer, but I'm not sure. Never found some useful resources about that. Maybe reduce the resistance of the...

dkbuilder is based on this thesis: https://www.vut.cz/www_base/zav_prace_soubor_verejne.php?file_id=60090 you'll find our implementation for the models in DK/models.py

> Ok, so parasitic capacitance (Miller effect) is not simulated/modeled. > This is something to consider since it plays a huge role in the frequency response of analog circuitry. Yes,...
