My Warpig "howles"
« on: September 09, 2011, 04:13:11 PM »
Hey guys,
I have a set of Warpigs in my Ibanez and when I practice with my band at loud volumes my Warpig starts howling.
I noticed that the bridge pup(ceramic) itself is swinging.
When I put my finger on the pup it stops. So is that what you would call being "microphonic" or is that a different problem?
Will it go away if I absorb the swinging with some stuff underneath the Pickup?

That's odd. Has it got the springs in there?

As far as I know, microphonic is when the turns of copper inside the coil are moving. If I'm wrong someone will correct it in a minute.

You've got 'broken' not microphonic  :D
Advice worth what you just paid for it.

Broken sounds bad but so does mircrophonic...
Either way I would have to turn them in to get it fixed right?

The spings on the sides are in and relatively tight as far as I remember.

I still hope its a problem I can fix on my own. For now I just try to prevent the pup from swinging with some rubber on the sides.

Picks would be handy. It could easily be the guitar.

the cover, if it has one, can also be microphonic. or any loose metal part that vibrates in the pickups magnetic field will have a similar effect

if your pickup is moving about easily it needs sturdier springs, rubber tubing or sponges underneath to hold it steady - that is the first thing to sort.

if it still squeals, and stops when you push on the cover then it may be the cover that is microphonic and needs a repot

Here are some pics of the troublemakers.
I blocked the trem-springs a while ago so that can't be the source of the problem.
As you can see the pickups are covered...
I also attempted to block the pickup-covers from swinging by shoving some rubber underneath it. It almost pushed my pickups a little bit up but it shuld do the job.
After testing it again I will post the results but I doubt that this will bring silence.

Thanks for the help so far.

Sounds like it could be microphonic feedback caused by an air gap between coils and metal cover

PLaying in rehearsal rooms- sometimes volume levels or Sound Pressure Levels can be pretty high  as you are often in an enclosed space and these problems show up more than they would in a live venue , but you still need to get it sorted .

It may be that the pickup would benefit from another wax dip (return it to BKP for this  - having contacted them first to explain what is going on)

I've just returned from our rehearsal room and testet the changes.
It is actually a lot better than before and I think I'm gonna wait until I change my strings next time so I can fit the rubber underneath a little bit better.
If it then still isn't better/gone I will contact BKP on how to proceed.

But as I was at our room I had the chance to A/B test our equipment and I noticed that my guitar produces a shiteload more feedback than my buddys guitar in general. In fact my guitar was next to unplayable over my bandmates amp without a noisegate and a few meters of distance.
His guitar(esp f250 passive emgs) wasn exactly quiet but not nearly as noisy as mine. :(
I that another clue that something is wrong with my pigs or is that because of the high output?

Just to clarify here is what we use:
Me: Ibanez S470(ceramic warpigs wit covers) -> Boss NS2 -> Maxon OD808 -> Mesa triple recto(new tubes) -> Orange cab
My buddy: LTD F250(passive emgs) -> Randall RH150 -> Marshall cab

I am also thankful for any tips on feedback prevention in general!

High output pickups paired with a high gain amp/sound will inevitably have some feedback its just the natural way of things.

It shouldnt be happening whilst you are playing though. Is it?

What i do is roll the volume back when im not playing or switch to a clean channel.

A noisegate will also do wonders with this

I always had my problems with the natural way of things ;)

It now doesn't happen whilst playing but in those in between moments when i stop playing after a palmmutet chord.

The noisegate does work wonders though.

yeah thats completely normal behaviour under high gain conditions.

Just get a noisegate that you can stick before the amps input and in the loop and youll be set

My own experience is you should have _less_ squealing with higher output pups (because you don't need as much preamp gain).

i can throw loads of gain on my warpig and it is not as noisy as your describing at all. 

I think something is definitely wrong with the pickup. 

I say send it back and get it checked out.  I know its a pain to not have the pup for a while, but
trying to macgyver the thing is not going to help in the long run.  Get it fixed and put that emg to shame!!

Problem solved!
I send it in and got it back last week.

Now the pigs only squeal when they should.

I tested it with lots of gain and without noisegate and it is so much better now!


Anyway I just wanted to let you know.
Thanks for the help!
