Pickups and milli volts : high output

Re: Pickups and milli volts : high output

The flux difference between PAFs and Filter'trons very similar when measured at the tops of the screws, because even though the Filter'trons have a double thick AlNiCo magnet, the metal fillister screws have a similar permeability, so much of the additional flux is lost in the screws, though the wider screw heads might be more efficient than the smaller radius screws and poles of the PAF. It's also possible that since the screw heads protrude more n a Filter'tron, they are set to be close to the strings than they would be for a PAF. In other words, I bet you can get a Filter'tron closer to the strings without it looking like it's closer to the strings.

As usual, I've posted my previous reply in order to share a slice of my experiments and as often, I'm way too busy to keep discussiong as much as wanted.
That said...
1) I see what you mean and I've no objection against your statements, although we could probably debate endlessly about the side effects of 12 poles protuding below the baseplate of a FT style PU;
2) When I attribute the output of TV Jones to their Gauss level, it's simply because I've measured this Gauss level.
If I put the Hall effect sensor of our lab teslameter a few mm above the poles in such a way that I read 42 G with a SH1 and 33G with an A2 P.A.F. clone, a TV Classic will measure 55 G (those are actual values measured in strictly similar conditions).

Do you make sure to set the pickups to a certain height? Strumming as hard as the string will allow sounds like a good idea, but it would only hold true for a given positions, like it will read more voltage in the neck position than the bridge, for the exact same pickup. You also want to strum in the same place every time, I'd recommend strumming over the 12th fret in order to put maximum energy into the strings, and not induce harmonic-specific excitation (which you hear very easily when you strum beside the bridge).

It goes without saying that my measurements for 12 or 13 years are done in defined situations, as close as possible to each others.

This makes sense; the 1400pF cap will move the resonant peak down into the lower harmonics, the stronger harmonics.

Yep, I lacked of time to describe the whole picture in my previous post above but I was sure anyway that someone would explain it for me. Thx for that...

what i can say is just an EMG sa-sv + EMG 85 = not good at all for a balanced sound
