I took my Epiphone Casino Coupe (see avatar) to the music store today to try an amp.

When I went to put it back into the case, a piece of white sponge/foam about 1" by 1" by 3" came into view inside the 'f ' hole of my guitar.

I asked one of the sales staff and Mike, the guitar tech, why it might be there.
Everyone was amazed and nobody knew what it was for. We had a good laugh.
These guitars are fully hollow, but I can't see how a small piece of foam like that could help control potential feedback.
Mike wondered if it was left in at the factory as it could be used as part of the build process. Like the sponge mistakingly left in the patient during surgery.

Any thoughts?

@Scotty and @Robert1950
If you look inside your Casino Coupes with a mirror, do you see any foam?

Cheers

Dave

Somebody probably read somewhere on the internet that inserting a piece of foam increases sustain, gives you better tone, prevents fret wear, improves tuning, prevents string breakage and guarantees you will lose 15 pounds in just seven days, all for just one payment of $19.95 plus shipping and handling! :)

I'm waiting for the free steak knives to arrive.

I don't have a small mirror. A limited flash light inspection did not reveal anything.

Did you buy that new Dave? If not, maybe the previous owner put foam inside the guitar to get rid of feedback and when he decided to sell it, took the foam out . Check if you could find other foam inside.

The truth is that on that guitar, "The Foam" and a little touch of glue is what holds the neck onto the body.
I would suggest you place it back ASAP...

The other explanation that makes sense to me is that the guitar such a lightweight ( I know cause I have held it),
Is that the factory folks added a bit of weight with the foam to stop the guitar from levitating into thin air.

Either way....no foam = no good

Good thing it wasn't a scalpel or a pair of scissors.

Seems like the feedback reduction (attempt) by previous owner may be a valid theory.
I had a couple of full-sized Casinos in the past, and the ease of getting feedback was a feature, not a fault! As long as I kept my hands on the strings and wasn't pointed straight at the amp, things could get pretty loud before the undesirable feedback kicked in.

I was thinking maybe there was a rattle or vibration inside at some point and that was an attempt to get rid of it. I know on my old Samick hollow body the stock wiring from the volume pot to the tone pot curled up and touched the top just enough to make a noise that sounds just like a loose pickup ring. Could have been a quick fix versus pulling the pots.

2) There is a surfeit of "tricks" people use when working on the electronics of semi-acoustic guitars, whether fully hollow or semi-hollow. Perhaps foam under the pots is one of them.
Very true. I wish I knew what the "trick" might be. Perhaps the foam was under the tone pots and I didn't see it. I looked at the volume pots and switch when I was buying the guitar to see if they were the full size or 'minis'.

Excellent thought.
Thanks for telling us about your Samick noise from the wiring

1) A dual palm-pedal? Be still my beating heart!

I want a dual palm Bigsby set up for my 335. I love benders.

Likely what happened was there was a new employee when that one was built and the supervisor told the new employee to put tone in the build and the new employee thought he said foam.;)

I never knew about benders until Ted McCarty himself pulled one off the shelf and showed it off to me, 36 years ago. Rich for my blood, but my ardour is maintained all these years later. C'mon 6/49, don't fail me now!

You should check out this product I saw at NAMM: TruV Volume Tremolo It's an electronic retrofit for Strat-type vibrato arms that lets you use it as a volume-swell device, while preserving normal pitch-bending. The arc of change can be adjusted to taste, and all the electronics and Li-ion battery are on the backplate over the springs. One can very easily achieve pedal-steel effects via movement of the vibrato arm. Had a long chat with the inventor/developer (who seemed REALLY pleased to be able to finally talk with someone about the technology, as opposed to retailers; pulling out a chair for me), and it's a smart product. I love simple ideas that facilitate creativity. As I drone on about incessantly, for me useful technology is something that makes a guy my age proclaim "Finally!", as opposedto makinga 19 year-old say "Kewl"..

I got into benders via Bernie Leadon.

I use a Hipshot B/G bender on my main Telecaster
