Thanks guys!!

Yep,
knobsocks are shrink wrap

- I've wanted knobs to be as low as possible to be protected against accidental detuning or injury by inaccurate stomping and I did not found any suitable knobs in shops around so far, so this is workaround
Lots of jacks - are they for patching the order of effects? - nope, besides obligatory in&out there are two
"monitor" outputs, one for tuner and one for further processing (envelope filter, noise-gate..), and then two stereo jacks for independent clean and over-drive FX loops.

Those knobsocks look pretty great, how were they made?
It's really just a shrink wrap (6-7mm diameter in "cold" state) cut to length 1mm over lenght of the shaft, put on the shaft and then shrinked above candle

Nice calm relaxing work
