First of all, this review must begin with a shoutout to Stan, who builds a darn good pickup, and gives them away. I won my choice of pickups in his monthly drawing and opted for a Hot J set (formerly known as the JuJu set -- and that's what the stickers on the bottom of mine said, but the box said Hot J ... maybe a famous transitional piece down the road ) Anyway, I opted for the Hot J's to tame my favorite beast, my Marcus Miller Jazz which is a bit zingy in the top end without any sort of passive treble rolloff. So some hot pickups, in theory, should take some zing off the top and tame the beast a bit. I discussed the possibility with Stan of possibly overwinding and he basically replied saying that these are quite hot already and should do what I'm looking for. I'm glad I listened to his advice. First of all, the product presentation was phenominal. I was expecting to wait a few weeks for the pickups because (I believe) they're wound order by order, and mine being free, I wouldn't expect them to be any sort of priority. I was surprised one day when I got a box I couldn't figure out what it was, picked it up and lo and behold it was from HAS Sound. Boy was I happy to see this. In the big box was a tshirt and a tiny little white box marked Hot J set. I open her up and there's a buisiness card, a bag of height adjustment screws, a promotional pick, foam for supporting the pickups, and lastly, two pickups carefully wrapped in foam sitting neatly in the bottom. Once I saw how much care he put into packaging the things, I knew they were going to be something really special. Installation was a breeze, just needed a screwdriver and a soldering iron (Stan uses vintage style cloth covered wire which can be pushed up and doesn't need to be stripped like a plastic coated wire) and took about 10 minutes. I screwed the pickups down and unfortunately stripped five of the eight screws that came with the pickups. Luckily I had spares because I was way too excited to wait for some new screws to arrive. Once I got everything settled down into place, I plugged in and was blown away. Stan's Hot J set is tonally very rich across the frequency spectrum, with a hint of treble rolled off to achieve aural bliss. The fundamentals were deep and throaty, and the overtones were rich and sweet. I took the bass from a burpy walking line to a smooth, sweet improvised solo at the 12th fret by changing nothing but my right hand attack and the pickups were right along with me showing no weaknesses. NOTE: Stan includes a Zap Strap kit with every purchase showing concern for our safety. I did not use this at this time but might install it in the future. I'll see what I can do about soundclips in the near future. I'll be taking these pickups for a slightly louder whirl tomorrow evening, hopefully one on one with a slightly insane guitarist to see how they cut, but there's no doubt in my mind, these pickups tamed the beast and educated it a bit too.
