I had a pair on an old Western Auto Duo Sonic shaped/sized thing way long ago(70s). I tossed em for a couple of used strat pickups but should not have. 10-12 yrs ago I had a really mistreated Teisco I picked up for 30 bucks at a pawnshop and tore apart planning to use the pickups in a lap steel build. BUt I never got around to doing it, was moving and got caught up in the getting rid of things mode and left it in a pile by the curb. So I'm still keeping my eye out for the odd old throwaway Teisco for super cheap, but it seems they have gotten favor with collectors so they are really hard to come by nowadays with ebay and all.
