I went to Lowes looking for a half dozen rubber grommets for my pickups. To my surprise, they wanted $1.27 for a single grommet! At RIC you can buy them for .30 each. Not a big deal but dang! Kenny, get ready for an order for a lotta grommets soon.

Not only that, our grommets won't eat your finish up as most grommets you buy over the counter do.

John, is that from out-gassing attacking the CV?

Most grommets are PVC which causes the finish to plasticize. Others are a type of rubber that is colored, believe it or not, with lampblack, which migrates through the finish.

Ours are a type that is non-reactive, or at least it's been true for a number of years. Don't ask me what type of rubber it is- I don't remember, it's been years since we did the testing- but I remember being amazed how many kinds there are. Here's a link to show what I mean:

Anyway, we found a source of the right kind and have stuck with it.

It was the same with the 4001C bass key mounting pads; we had to test many kinds for reactivity with the finish.

John, what is the purpose of the rubber key-mounting pad? Some basses have them, some don't. Is it a headstock-thickness or angle issue?

The keys have lugs that hold them together; without the pads, the keys won't set flat, can twist when screwed down, and also damage the finish.

Ain't that the truth!

In '90 I picked up a new 330, and the dealer (who shall remain nameless but is quite infamous) threw in some non-Ric grommets for me to change out on my guitar (so as to do away with those "ugly foam pads"). Said grommets ate away at my guitar's finish like termites. I've since replaced them with ye olde foam pads, like they're s'posed to be. At least the little circles where the wood is now exposed are covered by the pads...

There are three ways to tell vinyl grommets (the ones you DON'T want) from SBR rubber (the ones you DO).

Vinyl grommets are almost always shiny or glossy in appearance.

Do a bite test. Vinyl is quite hard at room temp, where SBR is like a good grade of calamari.

If they came in a plastic bag, sniff it. Vinyl smells like a kid's inflatable pool.

("What did you do at Home Depot this afternoon, Honey?"

"Sweetheart, I had a great afternoon sniffing GROMMET BAGS!")

Snigger...

The RIC fans in the SE (John Simmons, John Williams, etc.) are big on sniffing!

Simmons dared me to do it! And Paul, should I cook the calamari until they're "rubbery" before installing them?
