Does it have a neo in it?!
There are some more advanced measuring systems that try to take into account the magnets and ferrous components of a pickup, but they are still only measuring frequency response, not taking into account dynamics/feel, and are not including the strings/guitar/amp/player which are all very important. This is probably why these "breakthroughs" didn't really go anywhere and become an industry standard. I'm fascinated by this aspect of research though, and would love to explore more in that area.
i'm surprised there is no graph type of measurement for guitar pickups, but realize how daunting that could be. because--like mentioned--there are myriad post pickup variables that influence how a pickup will sound.
but you pickup guys have to take some responsibility in this as well.
now, don't get all defensive....
what i mean is, in lieu of being able to give any definitive tonal identifiers, a lot is left to "sounds like player a" stuff, or terms like that. some schmo (like me) might want to get a sound like one of my guitar heroes (i actually don't, i am just using this as a reference), and then when i get a pickup that was described as "so and so's sound", it sounds nothing like so and so's sound, due to my particular post pickup gear.
in my anecdotal findings, i can use dcr, in conjunction with magnets, wire, coil offset, etc to get me something that closely resembles what i'm looking for. but the pickups are only a part of the equation. the amp(s) are even more important. i can't expect to sound like junior brown, if i'm playing through a jcm 800. no pickup is going to do that for me.
You mean like this? I was comparing resonant frequency of a Tele neck VS Tele bridge.
I think it's cool and informative, but the biggest problem with this type thing is there's no standardized method for measuring pickups and no standardized tools. We'd all need to get onboard to make a universal set of techniques for analysis. So why doesn't that happen? It would greatly interfere with marketing hype and the mythos that's been cultivated through years of misdirection by a lot of guys who sling copper
Generalized specs that are actually floating data (DC, wire type, magnet type, metals) are easy to measure with simple devices and really tell jacksh*t about the pickups so preserve the hard data that all winders keep as proprietary.
Now you are putting words in my mouth that I never said. As far as being argumentative, you just proved my point. Thank you.
...what I mean is, induction frequency tests "ignore" the magnets and any steel, copper or brass etc. parts of the pickup and only measure how a coils responds to an oscillating electrical current. The result is just the coil responding to electrical induction, acting like the secondary of a transformer. So if you swapped a bunch of different AlNiCo magnets into those pickups, and graphed them all, the graphs would all look basically identical. ...but we know that swapping the magnets would significantly change the real-life sound of the pickups in a guitar.
