The Pickup Place / Re: New Tone Charts!?!
« Last post by DarthPhineas on Today at 07:40:08 AM »
What i would love for Dimarzio to do would be to publish inductance and resonant peak frequencies instead, together with oscilloscope traces like in the old 1978 catalog that i have.

adding inductance and resonant peak info puts any pickup maker ahead of the game.  no reason that a company like DiMarzio wouldn't already have that info.


I understand why it will probably never happen, but the major companies coming to an agreement on a standardization of mV measurements would be great for customers.... but these companies operate more out of fear that what can help customers might help customers choose another brand.  lol!

if you haven't already, go poke around http://www.billlawrence.com/

it's a must for any one that is genuinely curious about pickups.

he clarifies concepts such as DCR is not Output.  if magnets "age".  eddy currents.  mV output.  inductance.  and more.

there's a snippet in that site about how tolerances of the nature you're asking about can happen.  I've already laid it out, but maybe reading it from someone else might help clarify it better/more.

How much can we trust these charts?

I trust them only as a general starting point, and for some pickups it is not even that. I give you two examples under the old system (B/M/T):

Super Distortion 8/7/6, output 410
Breed Bridge 8/9/5, output 365

From that you would conclude that they do sound somewhat similar, the Breed maybe with a bit more mids, less highs and a bit less output.

Back-to-back experiment in practice (bridge position of a PRS Custom, standard tuning, 9-43 strings currently).
Result: they sound TOTALLY different. Not even close.

Super Distortion: heavy low/low mid emphasis, low end is tight but not super tight, midrange is rather dark (think of an "ah" vowel tone like in "bucket", not like in "bag"), the 1st and 2nd strings are very bright, bordering on thin/shrill, and that was with a load of approx. 375k. With 500k I expect that it would have been even brighter/thinner on the top strings. Very one dimensional overall in this guitar. Clean very dark but certainly workable.

Breed Bridge (with 500k load): heavy mid emphasis, mostly center mids but also low mids but overall the midrange is not as dark (think of an "aeh" vowel tone like in "bag"), loose low end, very smooth top end, a lot of fun to play overdriven single notes on the top two strings, nothing thin here and nothing edgy either. Clean very warm with almost no sparkle on top.

Cheers, Stephan

Hello,

No need to defend here. There was no intention to offend anybody from my side. I was just curious and surprised. DiMarzio certainly does a great job in producing their specific pickup models with consistent sonic properties.

with all encouragement to your efforts..... wind yourself a few hundred pickups (literally) and discover what anomalies you encounter along the way.  I'm guessing by that time that this random coil will make more sense by then.
Thanks for the advice ... we'll see ...

are those people saying the pickups sound balanced or have a balanced voice/character/tone?  or are they saying the specs off the meter show a balanced wind from one coil to another?
The statements are usually based on DCR.

Chasing DCR can be a fool's folly.  Two coils made with the same wire off the same spool can have the same # of turns and have different DCR.  Any one or combination of what was suggested (in the below quote) can apply, as well as any one of countless other oddities that really don't add up to a hill of beans.

At the end of the day, it could be simple.  One coil was made on one machine by one winder, and the other made on a different machine by a different winder.  Or one was made on Friday afternoon, and the other on Monday AM after a fresh calibration of the winder.  Or maybe a setting shifted and the pitch or tension were tweaked.  Or it was the same winder on the same machine made back-to-back with the same settings, but one coil was the end of a spool of wire and the other coil was from the beginning of another spool.  Or the winder did one coil before lunch, came back to do the second without getting all the sopressata washed off their fingers and it got on the tensioner felt.
I would have expected more consistency and repeatability from a series production like DiMarzio. I'm not a professional winder, just wound a few pickups by myself because of curiosity. Using a very simple winding rig and guiding the wire by hand, I have managed to wind coils that are really close to each other (DCR, Inductance and Capacitance). Would be strange to me that in a professional process there is that much variation.

and yet the late 1950s PAFs from Kalamazoo are some of the most coveted humbuckers out there.

those were made to a timer, not a counter.  a few seconds off could be dozens (or more) of turns on the coil.  they were tossed in a pile and an assembler down the line would just grab whatever off the top and put it in to whatever slot in the guitar.... no "neck" or "bridge" designation.  the materials used was whatever was available that day/week/month... could be alnico 2 on this batch and alnico 4 on that batch and alnico 5 on another.  the facility didn't have climate control as we know it and environmental concerns were like the wild west back then... so you could expect to find a steaming hot big room in the summer with the windows open and no a/c with a bunch of ladies smoking their unfiltered Camel cigarettes while winding with the ash tray (if there even was one) within inches of machinery that was pumping out pickups that some people are paying thousands of dollars for today just to put in a guitar that hangs on a wall in some lawyer's home office and gets the dust wiped off more than it gets played.

I'm not here to defend defend DiMarzio by any means.  but I might suggest than most current big-name pickup makers have consistency, repeatability, and a professional process that we might consider would blow away the conditions currently priceless Gibson humbuckers were made under.  I think Larry is a jackass and he should replace his office staff with ladies that don't have to ride brooms to work.  just as it's my opinion the Carter Duncan Corp (Seymour doesn't own it... and he's retired) is ran by a cabal of buffoons that I wouldn't trust to operate a deck of cards.  and even so, they seem to do well enough to be above the scrutiny of a set that you happen to have that has a spec that you don't understand.

with all encouragement to your efforts..... wind yourself a few hundred pickups (literally) and discover what anomalies you encounter along the way.  I'm guessing by that time that this random coil will make more sense by then.

Hello Darth,

What would be the inductance of each coil in @darthphineas set?
how would someone else know the readings that I took?  lol! I don't post every single spec that I get off every coil for this very reason.  it can/will confuse and/or obsess people with minutiae that can keep them from seeing the forest for the trees. 
I was hoping to be able to address the question to you in this forum. Also thought that the "@" would trigger a notification maybe ... didn't work. But finally you answered. Appreciate that!

Why is the difference so huge in my set (It is actually quite high to be explained by manufacturing tolerances in my opinion)?
But manufacturing tolerances are a fact.  I have 2 sets of these and none of the coils on the respective positions are identical.  In fact, one set has higher inductance on both pickups than the inductance on the other set.  There could be any one of a half-dozen solid reasons for the offset you are seeing in your readings.  Your answers will probably be found with DiMarzio tech support rather than on a forum.
Based on the statements found in various forums I was expecting to measure each coil at +/- 8.5K. So, it was surprising to me when the measurement was so different.

Another fun thing that I found: In the DiMarzio article about EVH it is mentioned that the "original" pickup  was a JB with the damaged coil that measured at something around 160K. So, I was just wondering what happens if I put a 150K resistor in series with my A5 Rough cast JB (which then is something like total 166K obviously). Tested it and found that it is even closer to my Axis Bridge Pickup than the JB alone. It reduces Output, Treble and the upper mid Honk of the JB, and emphasizes the low mids and bass response. Replacing the 150K resistor with a linear pot to play around with the resistance got me even closer in a range between 150K and 250K. When rolling the volume down the behaviour of that JB (with A5 rough Cast magnet and the added resistance) is very close to the Axis Bridge Humbucker. It cleans up very similar in terms of Output and retaining treble when rolled down. This, of course, is highly perceptive to what I hear in a direct comparison using my rig. For me it's as close as you can get at the moment. Closer than Tone Zone, Half-Aired Tone Zone, AT-1 or whatever other alternatives you can find in many discussions.

Jörg,

If I could take a look at your post and maybe unpack a few things

"there are many statements made that the coils of this Humbucker are balanced."
are those people saying the pickups sound balanced or have a balanced voice/character/tone?  or are they saying the specs off the meter show a balanced wind from one coil to another? 

What would be the inductance of each coil in @darthphineas set?
how would someone else know the readings that I took?  lol! I don't post every single spec that I get off every coil for this very reason.  it can/will confuse and/or obsess people with minutiae that can keep them from seeing the forest for the trees.

I would have expected the inductance to be closer, if not greater for the screw coil (based on the higher DCR).
There's no rule that the higher the resistance, the higher the inductance.  I have examples of the same model where there's a lower DCR and a higher H.  In fact, in instances where I see that, I prefer the sound of a lower DCR and higher H to the same model with a higher DCR and lower H (in the relative comparison) - but that's me.  Yet it is good to be aware of inductance in the same way it's good to be aware of distributed capacitance, as the notion of DCR being "THE" measurement has fooled too many for too long.  If you haven't already, go poke around Bill Lawrence's website (Wilde pickups) to read his take on Inductance as well as the Q Value.



my questions do not relate to the fact that I'm searching for a specific sound. It rather comes from the mystery that is made around this pickup and understanding the parameters of influencing a pickup's sound.

Here's the part that really matters:

At the end of the day, it could be simple.  One coil was made on one machine by one winder, and the other made on a different machine by a different winder.  Or one was made on Friday afternoon, and the other on Monday AM after a fresh calibration of the winder.  Or maybe a setting shifted and the pitch or tension were tweaked.  Or it was the same winder on the same machine made back-to-back with the same settings, but one coil was the end of a spool of wire and the other coil was from the beginning of another spool.  Or the winder did one coil before lunch, came back to do the second without getting all the sopressata washed off their fingers and it got on the tensioner felt.

The standard resistor values would give the following loads (approx) with a 500k pot:

470k - 235k
1meg - 330k
1.5meg - 365k
1.65meg (i.e. 2 x 3.3meg in parallel) - 385k
2.2meg - 410k

Good luck,
Stephan

To my ears, the JB and Custom 5 are totally different. JB is very midrangey whereas the Custom 5 is more "bigger PAF". Norton is closer to the Custom 5 than it is to the JB but more aggressive. AT-1 is closer to the JB. If "cocked wah" is to be avoided I would prefer the Custom 5/Norton to JB/AT-1.

Cheers Stephan
