I frequently see people talking about neck pickup full up and about a quarter of the bridge. (Or some variation of a blend, pick your favorite ratio.) I don’t know about you, but on every bass that I’ve owned the blend knob acts essentiall as a three way switch. There is maybe the tiniest of windows next the the center detent where you have an extremely quick slope of a blend, but after that it doesn’t matter if you’re at 0 or 49%, you have all neck. 51% or 100 gives you all bridge. Similarly with a VVT setup, you get one pickup until you have the volumes matching. This would be different with something the the Audere preamp or th J-Retro that have active blends. But since most basses have passive blend, it really seems to be all or nothing when it comes to blends. I hear no difference between a quarter or zero.
