I know there are at least a few participants here who have guitars, so I was
wondering if anyone here has attemped a Ringer Test (inductor Q) on guitar
pickups.
I haven't tried the pickup in a guitar, so I don't know if it plays OK, or
not. I disassembled it to install a 4-conductor shielded cable (with coils
split) instead of the single coax lead (coils wired in series).
The combined DC resistance of the 2 coils is about 13k ohms.
I have a used Epiphone humbucker here which I removed the cable from, and
figgered I try ringing the coils (separately) with a Sencore Z-Meter LC77.
I remembered that the Z-Meter manuals specifically state that these testers
work with inductors with powdered iron/ferrite-type cores (not steel such as
power transformers), so I removed the steel screws, but the coils still only
have 4 rings.
So the bobbins are removed from the frame plate and magnet, and have no
screws in them.. which should just be a plastic bobbin with hundreds of
turns of very fine wire on them (one turn would be ~5").
The wire size is probably about 40 gage, not sure about that, but very fine
wire anyway.
This pickup isn't important (not rare/valuable), since I bought a couple
just for studying and experimentation.
Any enlightening thoughts would be appreciated. <-- that's not a weather
condition or a skin treatment.
