  • Antigua Tele, you helped a couple years ago by providing some criticism and instruction while keeping an open mind when I was launching my pickups in a Kickstarter campaign. The tips were accurate & very helpful! (In a nutshell I was adding partial coils to enhance tone, which works really well so long as I throttle back other coils as I add new coils to the mix.) Anyway, I just wanted to say "thanks!"
    It is my understanding that the only reason a thinner wire coil can have a higher SNR is because more wire is closer to the string, so the length of magnetized string vibrations over the coil are that much louder than any ambient EMI - - the core and magnetic configuration further improving SNR by however much.

    I'd be curious just how magnetic aperture affects the sound with the same coil. You could conduct a simple experiment with a very short ~1/8" coil and thin Nd magnets. Construct some type of consistent picking device. A pick attached to a stick anchored at the other end, and dropped down from the same height should do. Use two different magnet widths under the coil which goes under one string.

    Try a ~16" disk magnet about half the width of the coil, taped under the center of the coil. Then, try a ~32" thick disk magnet about the width of the coil (to provide about the same total string pull). Record the results to wave files. I'd like to examine those files if you end up doing it. You might need more distance from the string for the magnets not to cause string modulations.

    The different size magnets might affect the coil electrical properties which you could measure in advance. As I mentioned, I’m not convinced your meter provides accurate guitar pickup level inductance measurements. Still, other measurable properties would change if the magnets do affect anything.
