Seriously though, that'll be a piece of cake. I just have to wait 'til next week - when the "inspectors" aren't here. I have a nice range of CTS, DiMarzio, ALPS, Bournes, and a couple others to test.
I'll post results as soon as possible.
Finally, my tax dollars doing something worthwhile!

This I gotta see!

Re: Dimarzio Parts suck
Originally posted by Kent S.First a DC baseline test of measure the resistance of a 500k pot CW~CCW with a DMM with at least a 10 Meg input Z, then run a 1Vrms DC voltage (I mean reading the voltage with a true rms sensing meter) across it, check the resulting dc voltage (rms) with a meter with at least 10meg input Z. Correlate to see if the voltage obtained is consistant with what it should be according to whatever the measured DCR of the pot and the internal source resistance of the signal generator or voltage supply. Then put a 1V rms sine wave @100HZ. across the CW~CCW terminals,measure voltage;then apply 1Vrms sine wave @ 1kHz. measure voltage;then apply 1Vrms @ 10kHz. sine wave, measure voltage ... finally correlate the results to see. You can also run inductance sweeps, but you won'r find much ... a pot's normal capacitance in series is around 40pF I believe, capacitance also becomes and issue in that not only do pots load from R/Z but from bleeding highs to ground via their capacitance. The DCR/Z thing will be fine though.

Originally posted by ArtieTooAbsolutely! And thats exactly what the GuitarNuts site was talking about - the difference between high-voltage, high-current applications, and the low-voltage, low-current guitar signal.
You know . . . I work in Navy electronic calibration laboratory. I've got multi-million dollar test equipment all around me. Perhaps I can do a test . . .
(Suggest some parameters, what you'ld like to see.)

Originally posted by Kent S.I think on the OFHC thing you're intering into intentional overkill, although, I do think it makes a difference in speaker cables.
Originally posted by Kent S.... But I do wonder if we'd get the same specs that we get for resistance (using DC) as we would a say a sine wave at 1kHz., and at 10kHz.? :

Re: Dimarzio Parts suck
Originally posted by ArtieTooI don't want to say that you're wrong, because I know you have more experience in guitars than I do, but I do have difficulty accepting this. The difference in conductivity between the cheapest tin, and the most expensive gold-plated, oxygen-free copper isn't going to be significant within the context of a guitar signal. (IMHO)
There's a good article on this very subject, (relative to guitar cords), at the GuitarNuts website. And I don't necessarily take what that guy says as gospel either. He may not have anymore knowledge or experience as you do. But it fits with my own three decades of electronics/audio/pro-audio experience.
So I must ask: have you ever noticed a fidelity improvement by simply changing a pot in a guitar, that you're sure wasn't related to something else that may have changed at the same time. Like a subtle difference in the resistance values of the two pots for instance? Or an improvement in a "bad" solder connection?
If you say yes . . . I'll believe you.

GuitarNuts makes some valid points, but seems to concentrate more on bashing the myths than explaining what is ideal and mosy importantly... WHY.
Here are the most logical/intelligent articles I have found on the effects of cables, connectors, etc.... on an audio signal.
Electrons are just like water... they have to flow from the source to their destination... the higher the conductivity and less resistive the material the better... in the case of a high-impedance signal you also want low capacatince
The RESISTANCE part of a potentiometer is from the middle wiper(hot to output jack) to ground... the connection between the hot leg to the middle wiper has it's own characteristics of impedance/capacitance the can effect the flow of electrons.
Food for thought... WHY do the USA production Duncans sound so good... it's the quality of the materials such as the wire used to wind the coils.
Also... think of how different pickups sound... the difference between some is just the type of insulation that is on the wire!
Interestingly enough... so many people love the George L's cables which are technically not a very good design for guitar signal... especially the shielding...
There are marginal improvements that can be made by selecting certain grades of OFHC free cable (in regard to high Z cables), inductance also plays a small part (very small) in the tone also. Like I said, for me though it's normally the physical sturdiness, precision, and over all how *well* a part is made that contributes to it's life span, and the electrical tolerance and precision that relates to sonic performance. Also one might look up the White Paper pdfs off of Pro Co.'s site as well.

Originally posted by Benjy_26I always thought that Dimarzio just repackaged parts. All the pots I have are repacked CTS's from Dimarzio, so are the swsitches in my Strat and Tele and the switches in my Paul and Sheraton. The switches were all repacked Switchcraft hardware. They're good enough for me.
Other manufacturers do this as well, such as Peavyer repacking EH tubes and Dunlop Straplocks.

I'll just have to "experiment".

Originally posted by jmh151Mine weren't marked up, the receipt indicated they were made in Mexico. The pots are stamped Dimarzio. I called Dimarzio, and they indicated that they are CTS pots, but CTS now makes the pots in Mexico under Dimarzio's specs.

The quality of the materials it is constructed with makes a difference in the sound. The signal from the pickup has to pass through the wiper of the pot... the more conductive the material the better... same with internal wiring in your guitar and the cord that connects you to your amplifier.
Your signal is only as good as it's weakest link!
Needless to say, it does not matter WHERE something is made... WHAT it is made of is much more important.
