Re: Dimarzio 36th Anniversary PAF set, whats its Duncan equal ?
There's no Duncan equivalent to the DiMarzio 36th PAF set, because…
1-"PAF" is a DiMarzio trademark, not to be confused with P.A.F. (Patent Applied For).
2- I don't remember any Duncan set exhibiting the DCR & Inductance of the 36th's… On those that I've tested, I've measured 9.36k for 5.47H (bridge: it would be considered as "overwound" for a P.A.F. clone) and 7.51k for 4.23H (neck). These last specs might seem close to those a SH1 neck (measuring roughly 7.5k and 4.2H) BUT I know that other people have measured higher values than me on other examples of the 36th neck model.
3-Physically, 36th’s differ from the old DP103's, which were already not vintage correct as P.A.F. clones. According to the technologies mentioned above by Rex_Rocker, New DP103's / 36th include embedded slugs between the usual poles in their bobbins and their magnet is separated from their pole pieces by plastic (silicone?) circles. They have no maple spacer nor keeper bar. Their mag is not rough cast. There’s no Duncan pickup like that, partly because it involves DiMarzio patents and partly because Duncan HB’s are closer to real P.A.F.’s.
4-Visually, when their bobbins are double cream (like in the set that I've tested), 36th’s s have a specific color, patented by DiMarzio in order to forbid to other winders to use it. Granted, there's double cream Seth Lover's, for example, but this color is initially hidden under their cover because of the mentioned patent.
5-Sonically, 36th's produce non typical twin resonant peaks, hence a non typical harmonic spectrum. I don't remember if they're listed among Dual-Resonance models (to name another DM patent) but IME, they behave as such. To me, the sound obtained has a kind of "hybrid" texture, not vintage nor modern, with less harmonic richness than P.A.F.’s or their variations.
Personally, I've not liked the 36th's that I've tested: they gave me the same kind of sensations than aspartame compared to cane sugar. YMMV.
