The Pickup Place / Re: Larry DiMarzio
« on: December 14, 2019, 12:40:37 pm »
Hi DarthPhineas,

In regards to DiMarzio single coils, why doesnít DiMarzio use eyelets in their bobbins, like Fender and Duncan.  They wire the lead wires inside  the coil like a humbucker.  It seems the eyelets would be more durable and easier to repair the leads.  Iím not sure what DiMarzio does to reinforce the lead wires in the coil.  Iíve never pulled off the tape on the FS1.  Maybe you can discuss this further.  TY!!!

They do on the vintage style pickups.

The modern style pickups have plastic bobbins.

The Pickup Place / Re: Pickup tone vs hearing tone
« on: November 06, 2019, 12:44:45 pm »
I think itís also your perception. When I first heard a music CD I thought it sounded too bright. Thatís because I was used to the soft top end of vinyl. But then I got used to it and it sounds right to me.

I hear a lot of guitarists that donít use much treble. And you canít really hear what they are playing in a band context. But it hinds sloppy playing well. lol.

As we get better you learn how to get the tone from the way you play. Then you gravitate to brighter guitar tones.

I like bright humbuckers. Kind of like big single coils.

They arenít a huge operation. I worked there for a short while. They do make a lot of pickups every day. They make a lot of pickups for Ibanez and Ernie Ball. Pretty much all their OEM pickups.

The thing that impressed me most was how many custom pole pieces and magnets they use. It makes Duncan pickups seem very generic (not that they arenít also good)

Iím guessing that they dropped models that didnít sell well.

They will make custom orders if you want something they donít currently make. They still know how and have all the parts.

I donít know who Gabby is, but Larryís daughter is the CEO. I never met Larry or Steve when I was there.

DiMarzio can make anything you need. When I worked there I was working on pickups for Ibanez, Ernie Ball, and just regular people that wanted something custom, usually bobbin color or polarity.
Itís actually a fairly small company.

The Pickup Place / Re: Where to find 51.5mm spacer?

That should work. DiMarzio uses metal shims on a few pickups. You can use key way stock for shims

They sell 50mm keepers here. Iíve never seen a 51 or 52mm keeper.

You wired it wrong. 

Red is hot, green is ground. Black and white connect together.

The Pickup Place / Re: PAF DP103 50th Anniversary
« on: August 24, 2019, 07:25:30 pm »
Their original PAF was a fairly standard design humbucker.  Everyone and their mother makes one of those. Duncan makes several. It was a nice sounding pickup.

When they first came out back in the 70s, the guitarist in my band gave me a set of patent label pickups out of his Ď59 Les Paul (used to be a gold top with P-90s) and had me install the DiMarzios. They sounded better than the Gibson pickups.

The Anniversary pickups use the air gap to simulate an Alnico II magnet. They also have the iron slugs between the poles to increase the inductance. As you probably know, these were tuned to sound like Larryís personal Les Paul.

Maybe the original model didnít sell all that well?

To my ears the Duncan Alnico II Pros are very similar sounding pickups.

The Pickup Place / Re: Cap for ash guitar?
« on: July 19, 2019, 03:09:36 am »
Keep in mind that the cap only comes into play when the tone control is turned down. Otherwise itís the resistance of the pot affecting the tone.

What type of tone do you want with the control turned down? If you want mud use a larger value like .047uF. If you just want to remove the top end while leaving the mids intact then use something like .01uF.

Also the hotter the pickups the greater the resonance in the circuit.

Just try some caps out. Thereís no right or wrong formula.

Fiberglass will have zero effect on the tone.

Copper is more conductive than nickel silver (white brass) so depending on how think it is can dull the tone.

I use fiberboard baseplates with thin copper foil for shielding. I donít notice any difference.

By the way, I donít hear any difference in your clips.

The Pickup Place / Re: Wax Potting vs Lacquer Potting....
« on: July 11, 2019, 06:49:41 pm »
I was hoping you would respond here. You know soooo much more about this than I do.  Iím still learning how all of this works.
I did discover that somehow I lost the spacer in my pickup when I was mag swapping. I searched for it but just canít find it. Thereís a better than probable chance that, that is causing my squealing. I ordered a couple which arrived today and this weekend Iíll install it and pot the pickup and see how it goes.
I bought a small crock pot and 2 lbs of paraffin, which I have already melted. Iím going to make a jig to hold the pickup submerged in the wax!

Ok, you took the pickup apart and lost the spacer. So the parts are not secure.

So you need to get something in there so no part of the pickup can move. A little wiggle translates to a lot of squealing.

You can buy the spacers on line.

Bill Lawrence used epoxy, but Iím unsure if he used wax as well.

I use epoxy on my bass pickups. They still have to be wax potted. The epoxy doesnít deep in.

Not sure if you saw my wax potting thread on he Duncan forum.
Anyway, I have a pickup that needs to be potted. In my research Iíve learned the main reason that most prefer wax is that once you lacquer a pickup, there is no fixing it if anything should ever go wrong in the future. With wax you can always carefully pick it away if you ever needed to.
Iíll be potting my pickup this weekend. Fingers crossed....Iíll be busting my cherry.  Lol

Iím a pickup maker. Back in 2005 I experimented with using lacquer, varnish, or polyurethane for potting. Even did one with super glue!

The problems I found were that the inside wraps were left unpotted. So you still got squealing, and as you said, you need to cut the coil off as you canít unwind it. Not that I ever unwind coils.

I went back to wax because other methods didnít stop the microphonic squealing.

Iíve got a Parker P-38. It has my own pickups in it. They are all potted and outside of the guitar wonít squeal if placed by the speaker. 
But in some situations that guitar cab make a lot of noise near the amp.

Itís a very light weight and acoustically lively guitar. So I also hear my pick tapping the body.

But the high pitched feedback is usually lose parts near the pickup. Sometimes just tightening the screws that hold the bobbins in place helps.

I had a customer with a single coil size humbucker that would squeal near the amp. It was potted but I ended up firmly wrapping black cloth tape around it to stop any vibrations in the structure of the pickup, and that fixed it. The bobbins where able to vibrate a bit.

Whatís the problem?

Red is hot, green and bare are ground. Black and white connect together.

Then just follow any standard Strat wiring diagram.

It doesnít get very far into the coil, and sometimes doesnít dry fully. Fender also used self bonding wire.

They eventually went back to wax potting because it works better.
