: I recently replaced the stock pickups of my Mexico jazz with a set of Bartolini
: 9J1s. There is a drop in signal output when both volume controls are wide open. A 1/4 turn off of full open of either volume control returns the signal. The pickups are properly phased. As anyone experienced a similar problem? …….Thanks
I think this is normal, it may just be more pronounced with the Bartolinis. My MIM Fender Jazz with the stock pickups does the same thing. When you have both pickups at the same volume level, they are balanced and fully humbucking. As you change the level of one, they lose some of their humbucking qualities, and become like two single coils. It seems like when they are equal and the magnetic fields are canceling each other (noisewise), they also lose a little volume. It may be more obvious with the Bartolinis because they have stronger magnets or something. On my Jazz it is fairly subtle, but definately there.
