It's too bad that I only have this one, and the cover of the other one left. This one was in my old '71 Jazz (bridge position) for several years, but eventually came out for a QP, and went in a parts box for about the last fifteen years. It gives a reading of 8.7k, but I've not installed it in anything yet to know if it actually still works or not.
I remember it being fairly bright sounding, nothing great if soloed, but pretty good when both pickups and the tone knob were on full. I hope somebody can finally put my curiosity to rest here, as to who made these things.
