Since the raw input voltage is applied to C1, which is rated at 25V, you should keep the input voltage below this. Or replace C1 with a higher-voltage capacitor.
-
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?

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.
No public wish lists :(
