i put in the push pull tonight via the instructions. everything works and the single sounds good, but in single coil mode its really prone to external ac current noise…. at least i don't know how else to describe it.
seems that when facing south or north in my studio i get hum and noise thats very noisy, even to the point that when playing the guitar, the hum can still be heard. if i face east ,or west, the hum goes away
When playing in normal series hum bucking configuration, its totally quiet no matter which direction i face.
odd thing is, my emg 81x does this too….
