Mid 50's? Probably A3s. Really, "probably A3s" is likely the case clear though most of the 1950's until the end. I was leaning towards eras of more (though never finite) certainty.So what’s going on with the mid 50’s p90s compared to the early and late 50’s?
In the early 50's they are pretty much guaranteed to be some type of A3 magnets, having a particular sound. By the very late 50's, after Gibson had introduced humbuckers and was getting swinging with that. Like the humbuckers at that time, the P-90 coils also seem to consistently have the dark rusty color wire and the long bar magnets ground on both polar faces, just like the humbuckers. It appears to me there are lots of stronger magnets around 1959. I've really loved the sound of the A5 P-90s from 1959 guitars that I get. Very definitive of a crunchy, raunchy, jangly rock P-90 sound.
I say "it appears" because, even though I've had lots of P-90s from just 1959 serial guitars grace by benches, that's still a small sample in the big picture. There's always that thought in the back of my mind like, "Well, what if only this wire, or that style, or ones with bobbins from this run or whatever are more prone to failure so I see them in disproportion to others?" Those sort of thoughts can be haunting and, being a factual person in a field of speculation, I feel the need to put disclaimers in my statements for reasons like that. Being a reseller or collector, in that way, would be advantageous to a more uniform demographic of guitars for a database. Having a focus on repair and restoration, I get stuff that needs repair or restoration in greater proportions.
