I have an aguilar OBP-3 with dimarzio ultra jazz 5's. There is a slight loss of signal while blending pickups, pretty much at anywhere except full neck and full bridge. The signal gets quieter as your blend into both equally mixed. I was told this was normal with any pre-amp lacking an active blend. I wanted to know If I replaced the blend knob with two volumes, if that signal loss would dissapear. My jazz has two volumes and there is no loss of signal with both pickups full on To reiterate, the signal loss is not huge, but noticable. If I replace the blend and volume config with individual volumes, will there be no signal loss? Thanks for the replies.
