As some of you may have followed in an earlier post, I purchased a "Nancy Heart" set off eBay. Complete with the Nancy Heart. The set included the Nancy Heart proprietary glob of transistors, resistors, push/pull, etc. For the record Don has great disdain for this early attempt at the Roy sound. That being said, I found the nancy Heart set, when installed with the glob of parts, to be fun, yet mostly impractical for normal use. To cut the story short I ended up trying just the 2324 pickups (wich, as far as I can tell is the 1953 Neck pup (brass cover, A3 magnets, 6.1K) and the bridge I am unsure of the model. Worth noting is both neck and bridge for the set are labeled "2324 nancy." The bridge has slightly staggered poles and reads a paultry 5.67K on the ohm meter. This set sounds fantastic. It is a "quiet" set in that it's not really pushing the amp too hard. But the sound from the neck is very organic and acoustic. Very similar to a 335 neck with the unmistakeable tele bell tones. Woody, slightly nasaly/honkish, and just brilliant. I LOVE this neck pickup. The bridge, though a different read on the ohm meter, is perfectly balanced. it has a nice soft tele bridge sound. No ice pick at all, very resonant, quite microphonic (I resealed the loose baseplate with parafin too), and just a dream. These pickups both push the amp just fine, but love the help of a Ghetto Stomp (Greer Amplification) to help it over the edge. The middle position is just the perfect blend of the two. Again, a bit 335ish. I installed this set with a push/pull for series.parallel and the pulled position gives a nice warmer, relatively overdriven humbucker sound as only a tele can do with the neck and bridge. After much swapping of the following reviewed pickups, this set is the setup I finally left in. Having fallen in love with the 2324s (minus the Nancy Heart) I ordered up a set of Hot Bakelite. Wich turned out to be a 54 Neck (almost the opposite of the 2324 neck) which has a nickel chrome cover, A5 magnets, and is wired to 6.5K. This pickup is indeed ever so slightly hotter than the 2324 neck. But it has a lot less of an organic feel to it. Not as "acoustic" sounding as the 2324. This is not a flaw, but is by design. it's a different sound. Closer to, but not at all exactly like, a strat's neck pickup. It's a wonderful sound that is different enough that I will gladly put it in the neck of my next tele. The bridge was an A5 magnificent 7. This pickup I was not at all happy with. It sounded very pushed. And yet seemed as though the high and low ends of the signal were clipped. had loads of twang and behaved like a tele bridge pickuo should, and it loved the tweed amp, but it just seemed lacking in a dynamic range to me. After going back and forth with Don, it turns out this is what this pickup is supposed to sound like. its a very specific pickup for a specific sound. I simply didn't know what I wanted. After I explained my problems with the pickup Don said he knew more what I was looking for. My replacement was a 0038 wound to 10K - His very popular "Keefer" model. I scoffed at it as it was wound to 10K. And I already was not a fan of the bridge pup wound to 7K. But as we all know, ohm readings are by no means the end-all be-all of defining a pickups sound. As such, I went and installed it. Yay! Love! Thankfully it didn't at all sound like a hotter pickup, but it was indeed hot. Very loud compared to both the 2324 neck as well as the 54 neck. As such, it was not well suited for middle position or the pulled humbucker position. it overpowered the neck and added too much twang (for my tastest anyway) to the middle position. This pickup is well suited for someone who wants that very desireable bridge-only twang. The 0038 10K was much hotter than the Magnificient 7 A5, but retains ALL of the treble and low end that seemed missing in the Magnificient 7. This also means my Twinlux loved the pickup. Easily gave the amp LOTS to play with and was very responsive. The pickup is very sensitive to style and touch, moreso than your typical tele pickups (wich says a lot). In the end, I generally play clean most of the time, and use the neck and middle positions far more than the bridge. So the Keefer came out and is awaiting my next tele with Don's 54 neck. So that's my experience with 5 of Don's pickups. Oddly enough I ended up keeping the ebay 2324s in my tele. At a 6.1K neck and a 5.7L bridge they are indeed quieter than typical, but only by a small margin. And this margin can be overcome with virtually any pedal if desired. For my sound I generally run straight into a Tweed or my Fishman Loudbox Mini. The 2324 neck, with the Loudbox Mini gives a jazzbox sound that is to die for. It out 335s a 335. The Nancy heart mess is in my parts bin as a momento. I know Don has orphaned this thing, and I guess I understand why, but it's still cool. It represents Don's quest for a specific sound and sure has a lot of thought and creativity in there. Side note is that Don is definitely a character. A very direct way of talking, extremely candid, never rude. The pickups are expensive, but he makes it a personal note of pride to make sure you the customer get exactly what you're looking for. And when you explain to him the sound you want, and he suggests a pickup - the guy is usually dead-on right. Hopefully this review can help some of you. I have a 0038 Keefer 10K and a 54 Neck that are just waiting for my next tele so I can slap 'em in there. Cheers guys!
