Just another addendum to my experiments with the Holy Diver. I recently got a second Fender Contemporary Stratocaster identical to the one I already have (again basswood, except it's HH, not HSS). I put my old Dimarzio Super Distortion in it that was in my other strat, and it's just so much livelier and punchy than the Diver. I've been playing them back and forth, comparing soloing, rhythm, etc... and I'm just liking the Super Distortion much better for these guitars, my style, and the tone in my head.
It sucks because originally I had my HSS strat with the Super D, and a Charvel San Dimas with the JB, and I was looking for a pickup replacement that would give me the best of both worlds. On paper, the Holy Diver seemed like what I wanted. On first listen, I really liked the Diver, it had the tightness and thickness of the Super D for rhythm, while having that singing middy quality of the JB for leads. The clearness and string-to-string separation of the Diver is fantastic when playing chords. It didn't have the harsh mids that the Super D gets with higher gain, nor the signature mid-spike of the JB that many find annoying.
But... while improving on those pickups and their negative characteristics, in the end, I feel the Diver is missing the special charm of those pickups... the forcefulness and punch, that over-the-top 80's feel. When I play my Charvel with the JB, I get a big smile on my face. When I play my HSS strat with the Super D, I get a big smile on my face. The Holy Diver, I just seem to be fighting with it the whole time to get that forcefulness back.
Now don't get me wrong, the Diver has its own thing going, I can see why people would love the pickup for AIC and Tool-like music. I think it has a much more contemporary sound than it is credited for (by calling it an 80's pickup). That clearness and hearing every string in the chord is a fantastic quality, and kills the SD and JB in that department, and I can also tell that the Diver does not fall over with high-gain, and leans more to a progressive sound too. But after trying it in the alder Charvel, and the basswood Strat, I find (as the thread is named) it just doesn't have the "beef". Maybe it's that less output and force that gives it those "clear" characteristics I do like so it's down to a sound trade-off really.
I have a hunch that this pickup is much better suited to a Les Paul, or other huge chunk of mahogany where the full body can shine through the pickup. Per its description, I don't think it's all that great in lighter bolt-on neck guitars myself, but hey, we all have our own sound we are looking for. I really do appreciate the sound it is going for and its qualities, and I really wanted to like it, but it's just not for my guitars I tried it in or my sound. Good thing there's lots of other BKP models to try!
