On my G string at about the 6th or 7th fret when I play the octave up harmonic plays MUCH louder than the actual note. I read that lowering the pickup might help. I have it lowered as far as it goes and it still rings loud. Even with the tone knob adjusted that harmonic is loud. I have a squire pbass affinity. Just the standard p pup. I also have Fender 9050L strings. Is ther anything I can do to the bass or do I need an EQ or something else to tone down the highs?
