My just finished project has an EB-3 Bridge pup in the neck position and Ceramic MM in the bridge spot. Passive controls are Volume, Blend, Tone. Volume and tone work like I would expect. But the Blend doesn't maintain the volume of the pickup as you move away from it and towards the other. Each pup is at it's max volume and tone on it's side of the sweep. Is this what a passive blend should do?
