Hi.. I've been hearing alot about buffered pickup blending, from J-retro users mostly, and I know how it works and all, but what I want to know is if really makes a difference? How do you hear it? I can understand that it could be nice if you had one pickup much more powerful than the other, or two pickups really close together, but on a normal J-bass, or a bass with two humbuckers relatively far a part, how do I notice the difference?? Are there any other companys that make a preamp with buffered pickup blending?
