The DiMarzio Model J sample does definitely sound pretty wrong! Either not wired properly or something else - sounds like a thin bridge pickup all the time (or something like a Warwick Thumb like somebody else said).
Great job though

all the .zip's went straight on my hard drive - if everybody else is wondering how the Model J's compare to the others sample wise, from my experience in my MM (I know that's a slightly roundabout comparison) the Aero sound clip sounds very curiously like my bass with Model J's recorded direct.
