    Anybody here have a McCarty pickup set up?
    Or as it's supposedly properly called a Gibson finger-rest pickup

    I was curious if someone did if they could measure the DC resistance of the pickups, individually.

    I was going to make my own version and though I suspect I know how the pickups are made (P-90 coils with alnico slug magnets)
    I was curious as to the specs.

    Thanks

    I'm using old McCarty pickguard/pickups on my L-7's and L-4c and have a few extras around...
    If I remember right most of mine measured in the lower to middle of the 6-7K range.
    I'll check again just to be sure.

    So back again and measured a couple......6.2K on one and about 6.4K on the other.

    I over-wound my coil and then un-wound it to this resistance.

    That is a beautiful sound!

    unless you know the exact gauge of the wire used for the original wrap, the resistance numbers are meaningless...the polepieces are indeed alnico rods...but again which specific alnico??..

    that pup was patented in 1948..so i wouldn't just assume #42 wire and alnico v rods

    other slim pickups of that era were using #44 and #45 wire!!

    also, very similar to a jazzmaster pickup!

    specs are close to a mid 60's tele neck pup..#43 wire..alnico rods...right around same resistance...only bobbin is different...

    nice work


    cheers
