So the "pedal" finally arived with the mail today, and I had a chance of testing it out.
I recorded a before the transformer was added audio clip and an after, and what I hear, though as expected subtle, is a somewhat tighter, yet somehow smoother, trancient and tone.
It doesn't sound like the kind you get from regular compression though (I don't like compression post production), it doesn't seem to mess with the overall dynamics or tone the same way a regular compressor would do (in fact it seems to almost do the oposite, exspand, instead of compress, at least as far as regards the tone, if that makes sense).
And while the difference is quite subtle, I do very much like what it does.
I got it located as the very last part of my "amp-less" pedal signal chain, right after my EQ based cab sim, boosting the signal into the 2020S, then into a simple tube preamp/DI, with the input gain adjusted accordingly (if the dB marks on the input gain knob of the preamp is reliable, and I can trust my ears and its input gain meter, then I have the signal into the 2020S boosted about +10dB or so, over unity).
Here the clips are, I tried keeping them at just about the same output level, exactly as recorded directly into my DAW, through my "amp-less" setup, no additional compression or effects added:

Yes Transformer:

And yes, this is how my basic "clean" tone sounds, on my main instrument, a 28.5" scale tenor bass guitar, in G#1 standard tuning.
