    Have a piece of foam rubber under each pup in my Studio since mhm.. nearly 20 years, just because i dont like the pup's to jiggle (is this the right word for it? ) when i'm playing. No vodoo, no sound enhancement or feedback elemination purposes..:thumb:

    I've only heard of foam in P90 routes since they go into the body and not on a mount ring

    On buckers...

    Just for unpotted or hollowbody feedback issues

    Which is why in that video, Seymour tosses the foam after repotting the offending neck pickup

    I'm in the 'just used for leveling the pickup' camp. Which is normally not necessary on an LP, more so needed on SG's as noted above.

    BUT - that is a killer Wine Red LP - can we get more pics of it???
    Is it a standard or ??? kewl...

    Really then you should laugh when someone tells you that PIO caps changes the tone or wrapping string around the stop changes tone.

    I have to surround the pups in my Paul to stop sympathetic feedback at the resonant freq.

    I use the less dense foam that the pups are packaged in.

    It makes all the difference in the world in taming that beast.

    I practice loud, so this is more of an issue for me.

    I put a block of foam under the strings between the bridge pup and the bridge on my bass guitar. It acts as a mute or dampener and gives the bass that upright doghouse bass sound. The foam is very loosely held in place by the strings.

    My first guitar was a used Epi LP I picked up at guitar center... I was pleasantly surprised when I saw the the previous owner replaced the pickups with Burstbucker 2&3's. They also had the foam placed in the cavity. I took out the foam and didn't notice any difference in sustain or tone... but then again, me ears weren't/arn't good enought to notice any differences.

    1) foam + nitrocellulose can = a tarry, gross mess, depending on the type of foam.
    2) foam does not increase sustain. Ever. Never ever.

    I can definitely see it helping with feedback in some guitars.

    A million years ago, I had foam inserts under the pickups in my 335; I also had thin metal pickup rings, and made small foam pads for underneath the rings to try to de-couple the pickups from the guitar as much as possible.

    I don't know what I was thinking - I was just a dumb kid - hey, but smart enough to save money enough to get a great guitar! The idea wasn't to dampen feedback; I loved and still love how crazy and alive a 335 gets when you play it really loudly. I just can't remember! except that, when I finally pulled all that crap out of there, the guitar sounded much better! :laugh2: And actually, you know, when I put some plastic pickup rings on the guitar, something more like the stock rings (which I think I broke - anyway, they are gone) I kind of thought, at the time, that I heard a bit of a change that I wasn't expecting and liked the plastic rings better. But I dunno, I wouldn't want to have to prove it. Probably it was a slight difference in height that changed the sound.

    A bit of foam might work great under P-90s in some guitars, but I'd make wood shims, myself.

    Adding foam under the pup can help with resonant issues and feedback, pretty common on single coil Tele bridge pickups and P90's to stop unwanted feedback at higher gain settings.

    I dare someone to use that spray foam in their pickup cavity and tell me if it enhances sustain.

    I like a bit of microphonics - but it's a fine line for sure.

    Springs under a P90 can bring out harmonics in a guitar that might not want to give them up so easily. They can also bring on way too much in other guitars, and in diff. playing situations cause all sorts of havoc. -But I wouldn't rule them out just for the sake of a lack of "pickup on wood contact."

    Tele bridges and bridge pickups can offer loads of explosive harmonics and dynamics, or uncontrollable microphics, squeal and feedback rendering the instrument unusable. I've fairly recently started messing with teles. My experience thus far is that air gaps between the bottom of the bridge pickup and baseplate is a major culprit of microphonics as well as ill fitting bridge to body connections. Mechanical connections are important; but foam is not my go-to prophylactic for microphonic issues.

    Make sure to use the proper tone foam.

    I do under the stock gibson P-90s in my SG.

    I have a dual P90 tele that's crammed tight with foam.
    One of these days I'm gonna try less foam, & then, maybe springs, just to get an idea of the differences described here.
