Polishing as a sound improvement?

Donner Guitars. Not a brand I hear much about.

They say

The inner cavity of this semi-hollow electric guitar has undergone six polishing, double the ordinary, for purer sound resonance.

Now I can barely think because my BS detector is going off so loudly. But sometimes the detector is too sensitive.

So given a semi-hollow electric guitar how much polishing is actually done in the inner cavity during construction? Does such polishing actually have a noticeable effect on the tone? Does or did Guild ever polish the cavity?

I'm gonna start marketing inner cavity polishing paste. I'll make tens of dollars!!

No. Just no.

Tone that's thick and rich. Uh huh. Sounds like the way someone would prefer their men/women..... thick and rich.

So this is marketing BS aimed at the entry level market where people don't know better and interior polishing lets them make unsubstantiated claims?

Interior polishing is good because it is "ordinarily" done (although there is no mention of who else does it).

Since interior polishing is good, ours is better because we do it twice as much.

" In addition, each guitar is manually processed for optimal resonance and ideal tone."

I mean, what more could one ask?

All the tuning forks I’ve ever seen have been polished, so makes sense to me!

I buy only Polish tuning forks, for reasons that need not be explained.

I think I've seen the Donner brand pop up in ads on Facebook and YouTube quite a few times. Very much at the budget end of the market!

Inner polishing - I better shut up - because this being a family oriented site.

OK - I change my mind - them cylinders in combustion engines have to be polished - other similar things in industrial mechanics, too.

But....can the wood still breathe if you polish it?!?

The tree is dead. Accept it......

I've seen some guitars constructed with (at least) partly finished interiors. It's kind of a nice touch, actually, but I do not have any strong feelings about it one way or the other. Does it have anything to do with sound? Highly doubtful.

Even Guild finished the inside of their guitars for a short while. Some time in the 80's I think??

From what I understand, some builders put a this coat of finish inside the guitar to prevent humidity from effecting the wood from the inside. Jimmy DeAquisto?

I bought a tuning fork from a guy who hand makes them in Leesburg VA in any freq you like, and it is rough finish, ground to the exact freq I suppose.

Looks like they have relocated to Florida but still have a NoVA area code phone listed on the site.

It's been a couple years since I bought the key in 432Hz, very nice key, rings so loud, afraid wife will complain as cabin fever has apparently set in already.

Back to the topic itself, most guitars look pretty rough on the inside, I like the idea of a tidier inside but face it, every pre war Martin has a rough interior with splats of white polishing compound like any other guitar, and they apparently sound quite good, as do all the old Guilds, Gibsons, etc.

Snake oil salesmanship endures.

Yes, Lake Worth: i.e., SOUTH Florida, the land of all sorts of quirkiness!
