Recently - i've had experience that goes contrary to what i THOUGHT i understood about pickups, and I am hoping someone can offer some sort of de-mystifying explanation. To keep this particular thread focused - i want to make clear that i am speaking about Telecaster NECK pickups. Consider these CONSTANTS : 43 Gauge Wire (plain enamel) Alnico 5 magnets Tele Neck Pickup with Nickel cover Distance of pickup from Strings Pot Values Neck material (maple) Body material (alder) Amp Player : Me Ok - my previous understanding was that 1) The lower the resistance/inductance/output, the wider the frequency spectrum of the signal - more highs, more lows, and an overall clearer cleaner tone. 2) The higher the resistance/inductance/output, the more narrow the frequency spectrum. more MIDS, less highs, less lows And recently - i had a custom pickup maker make me 2 pickups that were supposed to be the same configuration. Alnico 5, Plain Enamel Wire, Nickel cover. It so happens that with his inability to match the windings and/or resistance values exactly, i got two pickups that were significantly different. Pickup 1: DC Resistance = 6.0 Pickup 2: DC Resistance = 6.8 (I have measured these with an ohm meter that i know to be working perfectly and which has yielded consistent values with all manufacturers quoted specs in other pickups) To my incredible confusion.. Pickup 2 is MUCH brighter than Pickup #1. Pickup 1 is comparitively sounding like it’s under a blanket compared to #2. It can be perceived as if it has more bass, but i think that is because it is so lacking in high end. (note : after this finding i have measured other pickups in my other guitars, and in my backup stash and found this to be true of those pickups as well. The nearer to 6.0 the pickups go, the darker they sound, the nearer to 7.0 they go, the brighter they sound) With regard to the assumption of “more output = more mids, less highs” - does this ‘law’ have ‘transition’ point in it ? What i mean is - when you’re in the 6.0 range - is it a little ‘grey’ ? In other words, below 6.0, pickups definitely are brighter than pickups in the 7’s and 8s and above, but the 6.0 through 7.0 range is sort of the ‘fluctuation’ point for this law. Other questions : 1) Are all Alnico 5 magnets equal? Could one be STRONGER than another? Could that be contributing to what i am hearing? 2) Does the cover on a Tele neck pickup affect this rule of tone in a significant way? Hopefully my questions make sense. Any thoughts anyone can offer would be much appreciated. At this point, I’ve tried so many pickups, i just want to reliably be able to know exactly what I want - and how to get it - and i’m becoming a little frustrated. Thanks in advance for any help in understanding that anyone can provide.
