This will result in a much better and louder guitar, and unfortunately many a case of over zealous plastic coating down the Indonesian factory can result in several hundred grams of resonance damping tone death to have been applied.

There are specific manufacturers who are guilty of making quite nice guitars which they bury under a sheet of plastic, so you get this "dipped in glass" polyurethane finish. This same plastic can be used to make a variety of bushings and things like skateboard wheels with the softer durometers. It also doesn't like UV much, and is prone to all the crappy cracking/crazing/dulling issues that Polyurethane and Polyester boat varnishes are famous for, which is what these are.

Getting the stuff off is a nightmare, but if you can switch the finish of a guitar for the lightest dusting of french polish, with the faintest swish of mica grain filler, it'll sound loads better.

Removing the varnish can also require reducing the thickness of the guitar's top, which can be done in a skilled fashion and improve the overall quality of the instrument. Taking the bridge off is often required, but taking the top off is pretty drastic - you can usually get away without doing that.

Find an expensive guitar that just sounds like crap? It was probably nice before they turned it into a plastic sculpture and cast it into a block of resin.

Lots of guitars are in their realistic application, mostly ornament / status symbol. Especially expensive ones. They are basically wood-art, and there is a whole variety of ornamental abalone encrusted display instruments going back to antiquity which go with the ornamental swords, ornamental fruit trees, and so on.

The telecaster is a good, modern break with that tradition, cares mostly not what varnish you use, and can be used to knock down doors or break windows to escape from a burning building. No need to access that emergency hammer under that sheet of glass, I'll just reach for the telecaster. If you keep your "priceless" tele under glass, in case of fire I'll use mine to break the glass, and grab it on the way out. If you dent or refinish a telecaster it will basically sound the same. Nitrocellulose is what I'm on, and maybe you can hear the difference. That plastic varnish is mighty thick on some '80s Fenders, and getting rid of it will make the guitar feel lighter if not sound better.

For an acoustic guitar, thick paint or varnish can ruin the sound, and you'll think this manufacturer have lost their mind asking for money for such an instrument. All it took was the car painter to do a shift on the Takamine line. Suddenly hundreds of shiny guitars... that sound shit.
Truth. I got my hands on a fantastic 80s Japanese fender strat. It was covered in thick heavy blue resin. It took me three hours to with an electric sander to liberate it, but it is night and day better!

They typically sound and play pretty poorly but with a bunch of work, they can be killer. They used good wood and they're not valuable on their own so modding them is not a problem. I love rebuilding them and making them into good guitars. I play a 50's Harmony H-165 more than any guitar that I own. It's the guitar I leave out in the living room and it's great. I have a pile of broken ones in my shop and wish I had more time to fix them up or that there was a bigger demand for them. I would be completely happy if I could just work on them all day long.
I took Elisha up on this and received a rebuilt mahogany H-165 last week (I don't know the exact year, probably '60s). I've been playing it for days but truly bonded with it over the weekend. For what a pretty decent off the shelf Guitar Center acoustic costs I got a unique hand-rebuilt vintage instrument. Barebones looking, and it's hard to capture its charms in a pic but here it is anyway:

I got excited by some open drone-y chords and recorded a bit last night. Feels good giving this guitar a new life.
That's a beauty. Some of those old Harmony's were incredible. While not an acoustic, I have a '65 Harmony/Airline Bobkat that kicks ass. Nothing sounds like those old DeArmond pickups.
We're headed for social anarchy when people start pissing on bookstores.

Yeah, this is akin to people to take the skins and hardware off drums and hit the shell with a mallet. It's a thing you can do, I suppose. I'm not sure how it tells you more than just playing it how it will be played and how others would normally hear it.
Yeah, people seem to get cork sniffy about drum shell material and shell fundamental resonance, but I guess in my experience, maybe 85% of drum sound is technique+tuning+head selection+bearing edge. I’m quite sure I couldn’t blind-test ID my 60s round badge Gretsch vs a PDP if it had the same heads and a 1/4 round bearing edge.

Sorry to hijack the thread with drums! My acoustic is a Martin OM18 that has “nice” finish and construction but I was a lazy asshole and 15 dry ass New England winters put 3 cracks in the spruce top. Had it repaired and it sounds nice.

I think a lot of acoustic buyers are fine with it being a cowboy chord strummer, and a durable instrument that’s bright is desirable. I can’t help but think of commercial country and similar, where the acoustic guitar is almost like a percussion instrument.
