I have an inexpensive BRICE 5 String BAss that is my experimental toy. . . I recently routed in a Bartolini MM style pickup into the bridge location. It sounds great, but the Bartolini Pickup as much lower output than the stock Brice Jazz at the neck. These pickups are really Hot!!! Anyways, I can get somewhat close to balanced output by pushing the neck pickup WAY down, but the balance is not close enough. Is there any way to attenuate the signal that comes from this pickup without changing its tonal quality? Thanks!
