Thanks to my supporters, I was able to not only add strings to the Klang Fasa but also run this audio test.

of the Klang Fasa with a potential stereo configuration using a MakerHart Just Mixer - a battery powered stereo mixer

I found the knurling on the metal 3.5mm to 1/4” adapter plugs work perfectly to add texture to the sound.  

I have the signal running from the strings to the JustMixer -  then running through Korg's crazy sounding Monotron Delay

And then into my Guitar FX pedal board - using only the TC electronic FlashBack2 delay pedal

Thanks to all my supporters - there's lots of more tests to come ...and hopefully darker horror sounds...
