Seymour Duncan Quarter Pounder - Q's regarding

Post by othomas2 »

Didn't know whether to place this in the jag section or here... but yeah it's to do with a jag with an SD Quarter Pounder fitted to the bridge.

I changed from the stock pickup hoping to remove microphonic feedback... but this isn't the case... still evident on occasions on high tone settings and high gain... at reasonable volumes... I was hoping it would be able to handle this...

so my question is : are these pickups already wax potted from stock ? and would I gain any benefit from wax potting again whatever the answer ?

I've also heard about about lacquering pickups... is this from the spray can lacquer ?

Basically would like to deal with this issue... I've also been recommended to stuff tissue in and around the pickup... somethin' you would recommend ?? Is the jaguar claw causing a prob perhaps ??

I've done some reading, but would like to get some info and discuss here where there is some knowledge of fenders and jags etc...

any help would be appreciated...

thanks

Yeah, I had one in the bridge of my jag and it squealed like a bitch still.
Got rid of it in the end. Sorry, not much help.

It may be worth packing some rubber foam into the cavity to damp the vibration of the pickup.

I don't really know too much about it. but I think it's pretty likely that they are not wax potted stock. I've heard a little bit (was it bubbles that mentioned this?) that wax potting makes the pickup sound different. may or not be a bad thing, I have no idea. also, I don't think it is the claw, since the purpose of it is to shield the pickup, so I would think that would make it feedback less.

hopefully someone who knows more about jag pickups can help a little better.

any part of a pickups can cause microphonic feedback. I.E check every bit of it case, screws, claw, if these wobble or have any movement then they could cause feedbacks.

Hey Owen, did you buy the pickup off me? I think we met up in Shep Bush right??

Anyway first of all the quarter pounders are NOT wax potted as they don't come come with a cover. SD claim they are "vaccum potted" whatever that means.

By all reports, the first thing you should do is remove the jaguar claw. I've found quite a few reports on the net about them being microphonic and these have been fixed by removing the claw; i dont think it'll affect the sound at all, so worth a go.

If that doesn't help, you can wax pot it yourself or get a london guitar tech to do it - think they charge 10-20 quid. let us know how it goes!

Why remove the claw? What a load of crap. It could not cause microphonic feedback in any way, it is caused by cavitys inbetween the windings, bobbin and sometimes the cover.
And vacuum potted should be enough, its used on a lot of humbuckers nowadays without any problems whatsoever.
Its a single coil. They are not designed for high gain and the Jaguars electronics certainly dont help, 1meg pots>single coils>high gain= asking for trouble. Too much treble. A Strats pots are lower value and it does help the situation a bit more.
I've wax potted single coils before and they still scream at high gain, dont get me wrong though, it does help a little in moderation. Lacquer and wrapping the pup in tissue sounds ridiculous to me but go ahead and try it if you want.
Owen... like i said on another forum, your best bet is a single coil size humbucker.

I think not sitting in your bedroom would actually help. If you're in an actual band situation and not being a PUSSY then your pickups are:

a) not facing your amp

and

b) are further away.

c) Get on with it.

Some good advice there actually, i found standing at different angles with my back to a cranked JCM 2000 made a big difference. You have to be realistic with the gain levels as well, and use more bass control. Them 1meg pots are fucking shite with singles when using high gain. Alternatively, Fuzz pedals have always worked better with singles than straight distortion.

True words. People use too much gain to cover up shit playing.
