What is it about DiMarzio's and Feedback?

Most every DiMarzio pickup model I have owed, and there have been a lot, tend to feedback even when running a clean, but loud, amp. Even my GFS pickups don't do that. All of the Duncans I have used don't give me any unwanted feedback. Anyone else ever noticed this?

Nope!

All my DMZ's run dead quiet, but I have a few noisy Duncans!

Com si com sa.

I've never had a problem with any DiMarzios, feedback or otherwise.

Only on Dimarzio's I had in guitars back in the 70's and early 80's. My second electric, which I bought when I was a sophomore in 1980, had the PAF/Super Distortion combo and the Super Distortion squealed so bad it was unuseable.

Dimarzio fixed this problem AFAIK in the early or mid 80's. You're not playing "vintage" 70's and early 80's Dimarzio's are you? I wouldn't pay a dime for a Dimarzio pickup from that era.

All Dimarzio's I have used that were built since the mid 80's were properly potted and had no problem with microphonic feedback.

I've never had any issues like the ones you are describing. Dimarzio makes several great pickups and the ones I own are rock solid.
 
Re: What is it about DiMarzio's and Feedback?

I suggest that maybe all these pickups were previously owned by a person who was wearing out the screw treads?
 
Re: What is it about DiMarzio's and Feedback?

Owned lots of dimarzios so far and no feedback problems even under sometimes silly amounts of gain.
 
Re: What is it about DiMarzio's and Feedback?

Interesting...

The DiMarzios I currently own are:

1. Air Zone
2. Air Norton
3. Morse Bridge model
4. Morse Neck model
5. Single coils that are in the Morse

All were new....
 
Re: What is it about DiMarzio's and Feedback?

no feedback issues here either....I've owned an SDS-1, Tone Zone, HFH, Air Norton, and D-Sonic, and all were very good PU experiences...
 
Re: What is it about DiMarzio's and Feedback?

I have had some feedback problems with certain Dimarzios:

Brian May singles - May not have been potted to begin with and their magnets are loose and need to be glued in place.

Evolution - The 6 string model has a nasty lower midrange warble that was fixed by re-potting.

PAF - The one I have is from 1978 and the potting dried out and looked like boogers, so I re-potted.

those old Vintage 70's Dmarzio square tabs w/ brass backs are kind of sought after. You can pot em i suppose, and after all, they are vintage and vintage = best tone in most cases. I think it does in this case .
I lookat it this way. A vintage 70's PAF will cost you quite a pretty penny, and a very early production Dimarzio is just about as good and lots cheaper. Lots of those old Gibby PAF's squeal like Svinehundts!
 
Re: What is it about DiMarzio's and Feedback?

Apparently un-potted pickups "pick up" the body's resonance better than potted ones (yeah, heard that one just today in a guitar shop by one of the guys there :p) so, suck it up and bear with it :9:

Seriously now, no, I had a couple and used some more but no, never, however jsut choosing the right angle is usually enough to get rid of most of it...
 
Re: What is it about DiMarzio's and Feedback?

All me 'Marzio's've been very cooperative and've produced no unwanted feeback. Duncan's on the other hand've been noisy I find.
 
Re: What is it about DiMarzio's and Feedback?

Not one problem with any DiMarzio's I've tried either. Or with any Duncans for that matter. The only pickup I've ever had a problem regarding feedback/microphonics has been a Gibson Burst Bucker Pro.
 
Re: What is it about DiMarzio's and Feedback?

My Dimarzios were all dead quiet. I've never had any issues with them or Duncans for that matter....nor EMGs either. I guess I've been lucky. And I've used them all at gig-level volumes too.
 
Re: What is it about DiMarzio's and Feedback?

I've gotten feedback from my X2N when playing it boosted and through a Peavey XXX combo amp, cranked up to about 10:30.
 
Re: What is it about DiMarzio's and Feedback?

Never had any dimarzio problems but I HAVE had issues with feedbacky duncans (C5 and a Dimebucker) . . . I love them but theres some unwanted squeal, unlike my Anderson H3 which is DEAD quiet haha
 
Re: What is it about DiMarzio's and Feedback?

I think everyone is going to have different experiences, but I've probably owned 100 Dimarzios in my lifetime, and some have fed back. The one thing that sticks out in my mind are the pictures of Steve Morse with what is basically bathtub caulk gooped into his neck pickup cavity, all around the pickup. I read in an interview that it was to stop feedback. That was the only thing they found that solved it. So for years, that blue Steve Morse model EB/MM that he played had a grey-colored goober around the neck pickup. But then (and I can't remember where) I saw Joe Satriani with the same goober in one of his red JS guitars. Maybe the two of them spoke, I don't know.

Anyway there seems to be a little bit of "bonk" to some of my Dimarzio coils. There's a little more handling noise, if you bump them, or tap on them. But overall that's something I've experienced on every pickup maker across every type of pickup. Some do it, some don't. So I don't think it's inherent in their design. They glue and/or caulk everything together, so it's a pretty solid unit when it's done. Their wax seems to build up more, like it's a thicker mix than what we use, or they run a little cooler so the pickup chassis takes on more wax, and holds onto it. I think consistency is the key. No one likes it when they buy something and it performs a certain way, and then the next one they buy is different.
