Some pretty pics for a change, finished pickup rewind
With some 1960s Pekalit red bakelite and brass knobs that I happen to
have a
supply of, far more in keeping than the "original" ? grotty loking grey
aluminium Japanese ones.

owner agreed
(before tidying away the internal wiring)

I now know it is possible to remove pots and brasswork mounts through the
soundhole

ps
there may be disallowed remote linking with this host, anyone finding
that
please feedback here. Seems you sometimes have to repeat attempt to
access .

Would have been nice to see some pictures larger than 200x200 pixels.

Basics of frequency response of pickups anywhere?
Using a 390uH wire-ended axial choke for injector
in place of guitar string and an AF generator
and comparing roughly, the frequency response.
The rewind was about the same at 100Hz , less
at 1KHz and more at 8 KHz
Presumably more insulation on the replacement wire for less
distributed C, but mid-range drop ?
Can't do much about the choice of wire , so doesn't leave much to play with
