Pull the button nails out and replace them with an allen-headed set screw about 3/8" long, then put on the toaster covers. The newer high gains have allen button headed screws that are even easier to remove. This can ONLY be done on the newer (since the early 90s) plastic bobbin high gains. The earlier ones with a flat black top (not the newer 2 ridged tops) will damage the coil windings if you try to pull the poles out.
I glad someone else heard of this!! thank you for confirming,I thought I was loosin my marbles..
..have you done this personally? and does it effect the output of the pup?(make it weaker)..I think it was the older pup's that were being modified the way I described earlier(cutting or grinding the buttons as opposed to replacing the pole pieces)..
