SCHALLER DOUBLE J
1 3/8" X 3 9/16" with standard J screw mounts both sides
passive allen wrench adjustable bi-pole, 8 lead, quad - this pup has practically all the bells & whistles you could stick in a bass pup (looks like a pair of DM Model J's fused together)
wired parallel front coils and parallel rear coils
Loaded into an acoustically bright bass with the back J in standard position, bridge only no neck pup. Average output, maybe a little better. No hum/noise. Sensitivty to attack above average. Better than average sustain. Some finger/pic transfer but nothing of consequence. The pickup will produce an unpleasant "tick" if you strike the pup poles during solo or soft tunes. Pups worked well to both finger and flatpick.
Fun pup to play. Depending on setting and tune it was good vintage Fender J, or Ray bottomed, or decent vintage P. Pronounced characteristics were serious punch and bulge on E & A strings, strong low mids, pleasant but noticeably thinner mids and top. The punch could be a handful at times keeping volume under control as the E & A output was distinctly more apparent than D & G - but some tweaking should resolve that. It could also be moderated through tone adjustment but much tastier tone quality by controlling attack. I would have liked more bite in upper mids and top and a little more extension of frequency on the top but mids and top cut well so what's there comes through and is adequate, although I frequently found myself digging in more on D & G strings - but it worked well. Generally soft, rounded tones. Some rawness, growl, fuzz, and crunch.
Pup is sensitive to small variations in tone adjustment - a little tweaking went from no go to there. Also sensitive to variations in attack. More on the responsive than sensitive side to variations in hand position. Tone could be darkened/dirtied easily, cleared up to a lessor degree, and mids through top more thinned than brightened. Volume, tone, sensitivity, clarity, and cut as mentioned previously.
Pup worked better than average to all tunes with the exception of a couple, three tunes I couldn't get the tone before I was on to the next one (most tunes are abbreviated versions in order to fit them all in within a couple hours). Pup could and did function well without a neck pup and put out some pleasant tones that could work solo - though not what one would typically classify as a solo type sound.
FLUFF:
This pup was dropped in as I recieved it. I'm guessing adjusting the poles may even out the imbalance characteristics mentioned previously. The only time I've messed with adjustable poles, which are fairly rare except dimarzios, is with the DM DP 122 Model P and G&L L 2000's and I found doing so made no difference I could tell.
Not your ordinary pup from the gitgo. By far the most interesting pup purchase I can recall, most of which is amusing and was fun for me but of little value to anybody else. Suffice it to say there are others among us who took part and share this unusual pup so it will be interesting to hear feedback from them. Like LP's, To my knowledge, it's discontinued - and doesn't surface very often.
This is the first play of these pups and I'm looking forward to more and jacking with the myriad of wiring options at some point. Seems I recall there's a balance to be had between poles that's of significance and it's even possible I had these out of sync cause I didn't mess with looking into it. I wouldn't be suprised if the first guy that threw pups out of phase didn't say man that's screwed up but BB King said I do believe I'm sit'n on a goldmine. What I heard was good enough and better than most.
UPDATE:
As if this experience hasn't been bizarre enough, this guy just emailed me and says he has a few HUNDRED of these pups!!!
