S-100 pickups in the '70s

[mad dog]

Thinking I should have already purchase Hans' book, maybe the answer is in there ...

Qvart recently made mention of the perceived difference between the HBs in his '72 S-90 vs a '74 S-100, with the latter apparently being preferrable. He also mentioned hearing that the p/us had changed somehow in '73. Is that true? If so, when did the change happen? Would I be able to tell by serial number if a '73 has the earlier or later p/us?

Thanks all.

I'll see if I can scrounge up whatever site I vaguely remember seeing that on. And, BTW, I've never popped them out to see if there's any info to glean. No time when they're being played!

Of course I could be dreaming. But there is a difference. Or is there? Hmm...

I know of one difference which I mentioned in my picture post. The earlier HB-1s were not equipped for an in/out-of-phase option. The inference here is that the wiring after the windings would have to be different. As to the coil wire or winds per coil, I would be ill-qualified to answer. I too would like to know what other differences there were or if that is the only one.

So far I've found mention of new wiring and phase switches (in a catalog blurb next to a guitar with no phase switch). So maybe that's a piece of the puzzle. Or maybe it's just my particular guitars. Freaks!

I suppose I could test the older ones that I have lying around. I didn't use them in the Red because they weren't phase enabled. I'll get my digital multimeter out and give it a go.

Go for it. I don't have the testing gear. And as much as I geek out on research projects this is one for Hans to answer. All my search hits point to him anyway!

Of course, it could just be me. Or something else about the guitars. Who knows. I just play 'em.

oops, somehow submitted that one twice.

Now this one is empty.

More or less.

Move on, move on, nothing to see here...
