This is an odd one...
A coworker has a Rickenbacker Electro Spanish "Electric" Guitar made in 1935 and it has one of those funky old style pickups. I looks like someone may have changed the volume control pot at some point, but we are not sure. The pot has one of the 3-terminals on the end cut off and the way it is wired sort of looks similar to what you would do in a tone control configuration, but without the capacitor.
I searched around the web and found this:
"This entire unit is then mounted into the Bakelite cavity, and is height-adjustable by the twisting of two knurled, spring-loaded nuts. This height adjustment is, essentially, a slant adjustment that changes the relative distance of the pole pieces to the strings. The pole pieces are graduated in height from flush at the treble side to a .056" elevation at the bass end. The combined effects of low
magnetic pull in an opposing magnetic field, graduated pole pieces, and nonmagnetic hardware make this pickup a masterpiece in design for its time."
What we are trying to figure out is if this funky volume control wiring is correct or if someone did just replace the pot and wire it wrong.
Has anyone had any experience with these old guitar pickups?
