Hey DR, good on ya, I didn't know there were different model 57 re-issues
, according to the box it's a 57 classic and (I think, in the bridge of the SG) (Due to price being $299 AUD) they are a little cheaper now ? So When I bought the 2nd PU I asked for the same (not knowing about the classic vs classic plus) and what the box says it's a P94. Not that it sounds bad or anything but apparently the P94s' came in bridge and neck (reverse polarity) versions (which wasn't how it was sold to me, I just asked for a neck version of the 57, they said no difference just use the same, but not quite what I got..). Interestingly, I would never had looked except for this thread
Now I have to pull it out to check
Oh well, the SG could use new strings and a setup....
The idea behind the Ultrasonics was as a reference series PU, nice and flat freq response (I'm sure not entirely flat LoL, it is a guitar PU after all). As in, most guit PUs are quite middy, these were designed to be a "better" balance (bass, mid, treb) and they are
. Also very low noise (but still passive) and a range of outputs (ref: 1, 2, 3 (single (dingle :-)) coil size, ref 4, 5, 6 humbucker size), obviously bigger numbers = more output (e.g. my Anderson has Ref 6 and 2 x ref 3s'). SC helped me get a ref 3 from German evil bay, I put it in the neck of my Profile Tele, very nice
. They are rarer but there are still some around. You probably have to try, hear them to be as passionate as I am about them ??
