What do these #guitar #pickups sound like? I don't know yet; I haven't installed them. Here's what the numbers suggest.

Guitar strings move further at the neck pickup than at the bridge pickup. So ideally the bridge pickup should be more sensitive, or "hotter".

The Air Norton and the Satchur8 have similar total inductance. That would suggest similar sensitivity. But the magnetic structures are quite different. The "Air" in Air Norton refers to a gap in the structure.... 12/?

The Satchur8:
coil 1, 2.88 H, 5.77 kΩ
coil 2, 2.89 H, 7.22 kΩ
series, 6.64 H, 13.0 kΩ
parallel, 1.68 H, 3.21 kΩ

What's interesting about these numbers? DiMarzio claims that both of these #guitar #pickups (and many others they make) have coils with deliberately different resonant frequencies. And you can see this in the numbers.

The two coils of a #humbucker have to have the same inductance, or the hum canceling is diminished (i.e. more hum gets through).... 8/?

OK, let's cut to the chase. I don't have a rig for measuring resonant frequency, but I did get inductance and series resistance numbers for both #pickups.

Each pickup has two coils. I measured them individually, in series (the usual #humbucker configuration), and in parallel.

The Air Norton:
coil 1, 2.80 Henrys (inductance), 6.90k Ohms (resistance)
coil 2, 2.70 H, 5.35 kΩ
series: 6.41 H, 12.3 kΩ
parallel: 1.61 H, 3.02 kΩ

Back up a bit: a pure inductor (L) has no resistance (R) or capacitance (C). Real inductors have both. The result can be characterized as an RLC resonant circuit. It's easy to measure R, not as easy to measure L, and tricky to measure C, but you can infer C from the resonant frequency.

I picked up a Chinese RLC meter some time ago for other projects. So I dragged it out to get some measurements on the new DiMarzio #guitar #pickups.... 6/?

#Guitar #pickups are relatively big inductors, with very lumpy frequency responses. We'd like to know the output transfer curve, but there's no easy way to measure it, and too many variables.

It's easy to measure series resistance (R in #electronics speak). But it has almost no bearing on the output characteristics. Inductance (L) has a direct bearing on output, but requires fancier measurement gear.... 5/?

Hum from magnetic fields generated by AC power wiring is a problem with #guitar #pickups. A clever engineer in the 1950s put two similar coils next to each other, but reversed the magnetic and electric polarity on one of the coils ,and connected them in series. The result is that the hum signal is "bucked", or canceled, and the desired musical signal is doubled. "Humbucking" pickups or #humbuckers are in most electric guitars made today... 4/?

#Geek that I am, and knowing enough about #electronics to be dangerous, I got out an LCR meter to get a feel for what these #pickups are about. (How many other #guitarists do this??)

Guitar pickups are, in essence, nothing more than coils of wire wrapped around a magnetic structure. The technical term is "variable reluctance sensor". Since most guitarists don't know jack about electronics, there's a lot of mumbo-jumbo and cargo-cult mystique about pickups... 3/?

Sweetwater Sound had a Black Friday 25% off sale on DiMarzio #guitar #pickups. DiMarzio is one of the 2 best known makers of aftermarket pickups, Seymour Duncan being the other. Both have been at it since the 1970s.

I wanted pickups that were hotter, but not too hot, and better balanced than the originals. So I ordered an Air Norton for the neck and a Satchur8 for the bridge. They showed up yesterday... 2/?

PPS: Aaaaand I just realized, hours later, that I included absolutely no hashtags in this thread about #audiobooks and #audiobookproduction. Sooo … lemme do that here!
