Revived Pickup

I have this old Supro that the pickup would barely work and I found an old Bulk tape eraser that I purchased from Radio Shack about 20 years ago.
I set the tape eraser on the strings over the pickup and give it a few Seconds shot and I'll be doggoned, the pickup started working. Might not been the proper way of doing it, but now I can play the Supro with plenty of volume;
Maybe others can do similar to this????

Degaussers ... even small hand held ones ... produce strong enough fields to remag steel, ferrite, alnico and cunife magnets.

The problem is the orientation of the field ... degaussers usually produce "multi-pole" fields ... which would render a magnet useless ... that's what they are made to do.

Tape erasers ... particularly large expensive units ... may produce multi-poles if made with permanent magnets .... or a uniform field when electromagnets are employed.

Again, orientation is the key ... you must be able to pass the magnet thru the field and maintain the proper "pole" locations.

I've remaged a bunch of pickups ... where the owners used neodymium-iron-boron (sold by Stewart Mac, etc) to remag at home.

Again ... the problem is that NIBs are soooo strong ... they can produce very "funky" domain alignment ... which can do more harm than good.

Electromagnets are the way to go ... you can insure proper orientation ... hit the power ... charge ... kill the power ... remove the magnet.

Anyway ... good job Hill !!! ... Image
