It seems to me that you are simply overloading the input of the

It would seem so but "instrument level" isn't all that much
lower than nominal +4 dBu line level. I've seen more than 10
volts p/p coming off a guitar pickup. No, something's
strange and he needs to do some measurements and
troubleshooting.

I understand, but I wouldn't be at all surprised to find that a guitar could
overdrive his chorus pedal, as well. I have experienced that capability many
times, especially in post-'70s devices designed for "heavy metal" sounds.
