It measures whatever current you run through it. Voltage is irrelevant.
They’re calibrated during manufacture.
It senses current, not voltage. So the supply voltage is irrelevant (except for possible isolation concerns).
The output is an analog waveform that tracks the sensed current (with a DC offset of +2.5V assuming you’re using a 5V supply).

Great idea but not that useful due to limited selection of values. I’d prefer, say, 10 pcs of 2.5X more values. Or just a bigger kit.
Also, you need to specify the tolerance.

So what are the part number(s) of jacks that fit this board?
Tutorial - Op Amp Guitar Amplifier

I won’t comment on the lack of EQ or tone shaping, except to note that guitar amps are RADICALLY non-flat in frequency response.
And most guitar pickups need a higher input impedance than your 10K to avoid tone loss. The usual “standard” for guitar amps is 1M ohm.
