Searched, but can find few specifics about this passive splitter. I'm curious where it's intended to be used in the chain? Apparently it is "ideal for the galvanic isolation of high-impedance signals" but I am unsure what that means? Would it be best suited to being first in line, or after a buffer? Also, if first in line, will it change how a fuzz face sounds and cleans up in response to volume changes from the guitar? Many thanks.
