Tolerance is not the issue. When I mentioned C3, it's not the tolerance, it's the taper. I seriouslky doubt guitar amps use C3 pots.
According to That’s design note, the gain trajectory vary depending on the reverse pot tolerance.

Read again:
"Eigure 3 shows how the decibel gain of the circuit of Figure 2 varies with pot rotation using a 1510 and various 10 kΩ pots for RGV. The pots are all reverse audio (log) taper, usinga two-segment piece-wise linear approximation to the log function; the tapers vary from2.5% to 20%. "

Not tolerance, taper The graph shows clearly that C2.5 gives the smoothest law.
Who's right or wrong is irrelevant. What matters is what's right or wrong.
