>They have a insanely high DC resistance of 23.5K, which means a very high output...
I just checked the website and you're right!
Surely they redesigned them??? It's been 10 years or more since I had any of these and I can't remember the specs exactly, but I'm pretty, pretty, pretty sure they weren't above 8k. I bought the first YJM because I first saw a DiMarzio add where Malmsteen was going on about their low output, that's what he wanted so it wouldn't "color" his front end pedals (crap DOD clone of a Distortion +), and other blah, blah. I liked the lower output HS pickups I already had, so I checked the specs and got one myself. I didn't hear any significant difference between that and a regular HS2 and figured I wasted more money. In any event, I couldn't get any of the HS pickups or the YJM to match my backup guitar with EMG passives (~11k), so I resorted to the compressor to get their level up when I switched to the DiMarzio Strat.
Maybe I'm off my nut.
EDIT: I think I figured it out. They have a high DC resistance, but their voltage output is unusually low - 93mV compared to 160mV for their standard Fender replacement single. Maybe my memory replaced "93mV" for what I would expect to be "<8k" resistance. Anyway, I distinctly recall a low output from them and a compressor or clean boost of some sort may make the difference TEM is looking for. Or maybe not - tone is a funny thing.
