A friend asked me the other day to speculate on why the Gibson EB pickup (colloquially called the "mudbucker" is so muddy.
I don't know very much about the pickup, as I've never dissected or measured one, but I do know:
It's a double-coil design with a very large number of windings on each coil, a total DC resistance of about 30k, and (anecdotally/logically) a very high inductance relative to many other electric guitar/bass pickups.
My first thought was that maybe the high high inductance shiftsthe pickup's resonant frequency substantially lower than a "typical" design, and that maybe the high resistance sharpens the Q enough to make this lower resonance more-noticeable, compounding the "muddy" impression.
But then I started to think about the input impedance of a typical amplifier in relation to the much-higher-than-normal output impedance of the pickup, and began to wonder whether this could result in a treble-robbing loading behavior?
I wonder whether any of the smart people here have any input--in the meantime I'll reach out to my friend and see if he can get me an inductance measurement on the pickup
