John a compass will work fine.
Notice the gauss meter has + indicator but for just checking
polarity the little magnet in the tube for a couple of dollars or a compass
is much cheaper. A gauss meter hits in hundred $+.
Sound is the story. I plan on testing all of the Strat pups on one guitar.
I'm going to record it straight in. I'll record the original pup (in whatever position)
and then I'll record the one I rewound.
I'll be going for neck and bridge positions first as the middle is the singular.
I have to rewind one more before I attempt the potting. It'll be with 9,000 wraps then
I'll have two to sound check - each in neck and bridge position.
I may get the middle ready for test too but focus now is on neck and bridge.
The reasoning is - I want to have sound records of;
Original
Rewound with original magnets. 7,000 and 9,000 wraps. (whatever ohms it measures)
Completely new with magnets I charge. 7,000 and 9,000 wraps. (whatever ohms it measures)
I'm thinking the following test will be winding to the resistance (however many wraps).
Of course- all with the same wire and type of magnets.
I hope to have sound samples of the two- each in neck and bridge positions by the next
weekend ( 9-1). If all goes well I'll have the middle too. I have only one bobbin for middle so I'll go for 9,000 wraps on it.
I've thrown in a delay though. I have to build a round platter out of CD's. I have to find
out...I can't get it out of my head so I have to go for it. :)
I want the smoothest turn and smoothest wire guide I can get and I think the CD platter
will do that and wire guide is nothing more than fine sanding....now I have to rig up
a dial indicator ...sheesh.
