Although I can't find where he is quoted saying this, it's generally accepted that Seth Lover designed the humbucker to sound just like the P90, but without the hum of course. So let's turn the clock back to say, 1957. And let's say you have your back to a guy playing a 1956 Les Paul with P90s alternatively with a 1957 Les Paul with PAFs. Imagine the guitars are as close to identical as possible, and the player is playing at typical 1957 gain levels through a 1957-ish amp. How reliably do you think you could tell one from the other? I'm wondering a couple of things here: Is there really that much difference between vintage accurate P90s and PAFs, and if so, is that difference greater that the difference between individual pickup and guitar differences from the time period? And has the difference been exaggerated by all the different P90 and PAF so-called "clone" pickups on the market today? When a guy swears by P90s or PAFs, is he really swearing by the particular pickup he's playing, as opposed to any organic sound difference between P90s and PAFs in general? I'll be the first to admit that my tired old ears probably could not reliably tell the difference. What do you guys think?
