Hi there,
I use my Kemper as a kind of central hub for my guitar signal - it gets routed to a tuner, spdif, patchbay, pedalboard-> amp.
I noticed today with a new pedal that I was getting a ground loop issue with a particular fuzz pedal when using the kemper and it made me wonder what impedance the kemper is outputting? The ground loop button didn’t really help in this instance.
I’m guessing it’s like a buffered output in the 10k-100k range? Doesn’t seem to be listed in the official specs.
