What Is a Nitrocellulose Guitar Finish?

[@sweetwater]

The magic of a nitro finish! What do you like most about a nitrocellulose finish? ✨

[@hkguitar1984]

I have been playing guitar since the early 1970s, as such I've owned guitars with both nitrocellulose lacquer as well as the more modern urethane poly finishes. After +20 years the lacquer guitars are aging very nicely and look their age while the urethane poly finished guitars basically look brand new but dull. The way nitrocellulose ages is in my opinion much more desirable. After 20+ years of use and wear I regret purchasing the urethane/poly instruments as had they been finished in lacquer they would look and feel much nicer than they do now. The lacquer ages gracefully indeed.

[@fabulousfreddyisready]

@Bloom Tik Bloom You were an idiot to buy a nitro finished guitar then.... To those that desire a nitro finish the wear and colour fade/change is part of the experience...

[@russellzauner]

When people refer to "letting the instrument breathe" they're not talking about literal air. The higher elasticity and low degradation qualities of modern poly finishes "dampen" (not make it literally moist with fluid, mind you) the instrument's body and in an acoustic guitar that will remove distinctiveness from the build and flatten the character so it sounds a lot more like every other instrument with its dimensions and finish. It's not the actual gaps in the finish that allow vintage instruments to have the tones they do, it's that the finish itself lets the instrument physically react more naturally to itself and allow the vibrations (including a much richer subharmonic voice) to not only escape but interact in ways that add to the rich sweetness of the raw output. Since a solid body guitar can't really expand/contract like a hollow or acoustic, it's not as noticeable until amplified and the affected tonality will be swamped out if preamps are used to regenerate the signal with excessive shaping, rendering it fairly irrelevant for many users who enjoy a broad sampling of onboard preamplification/filters. I hope to experiment with french polish and various natural finishes, such as shellac, in the future. :-)

[@hkguitar1984]

@@russellzauner Well said Russell What you described is exactly what I have observed over the years (2 or more decades). As the lacquer hardens and thins the body wood seems to age into a more brittle/resonant form. Not all guitars, but many. Wood is such that it all doesn’t react/age exactly the same, similar perhaps but not the same. In some respects each guitar can be as different as individual people (IMHO), there are good and there are bad.

[@j_music_8779]

I love the feel and smell of a nitrocellulose guitar. I also really like that it ages well and gives you that cool vintage vibe. 🙌🏻

Being a Sweetwater customer I want to say Thank you for taking the time clearing up a lot of my own understanding of a Nitro finish.And hear I thought the wood could breath...What was I thinking!

[@jamesdalzell6741]

Its the only finish when you open the case and get that new guitar smell and makes you want more.

[@moustachio334]

Now I know those were potentially hazardous fumes I was smelling lmao. My SG sounded great and me a little high everytime I opened the case. Makes sense looking back it when I first got it. I love that smell though.

[@melodica5407]

I can just put vanilla flavor in my case

[@howabouthetruth2157]

YEP!!! Only 1 of my 4 acoustic guitars ( all purchased brand new within 7 months of each other ) has nitro, and you can definitely smell the difference vs the newer UV stuff.

[@majorlee1]

After watching the Gibson factory tour it is very cool to watch this. 👍

[@moustachio334]

I wish more people would watch Gibsons factory tour videos. They’d understand why it’s impossible for Gibson to price their guitars more fairly.

[@boldcautionproductions9203]

I didn't know a lot of the applications you talked about, surprised it was used on metal for cars. The big use of it was airplane covering with silk - for model airplane enthusiasts it is known as dope. Gave a really nice finish on silk airplane wings and fuselages. Loved the smell growing as a kid...

[@Poco50guitar]

I have been using nitro for quite a few yrs. on cabinets. I built a OM style guitar in 07 with a friend of mine and the finish still looks great. I like the way you can 2nd, and 3rd coat fairly quickly compaired to oil based finishes, and do repairs to it also. Now back in 07 when i built my OM guitar i was told by guitar suppliers that the nitro for guitars was different than cabinet makers nitro.,.i had my doubts but still bought it from them. I would like to really know if that was true or not....the instrument makers only sell there nitro for about 4 times the cost i could get nitro for cabinets...DAH. wasnt hard to figure that one out....anyway here is my 2 cent worth.

[@DojoOfCool]

What I was told back in the day that made nitro finish was desirable from being thinner the wood of the guitar body can outgas moisture easier and age faster than when thicker finishes are used.

[@cornbobrimlove7892]

Not true. More folklore nonsense from the so called "vintage" guitar community....

[@DojoOfCool]

Easy to disagree but I don't see your counter explanation.

[@cornbobrimlove7892]

@@DojoOfCool Shouldn't need one....but.....The finish seals the wood "AIR TIGHT". No moisture will escape through the finish. This is why so much care and prep is taken in insuring that the wood is as dry as possible BEFORE any finish is applied or even anything built from said wood material. Sealing of the wood is in fact the whole and sole purpose of applying a finish to it in the first place. Acoustic instruments dry from the inside...not out through the finish..

[@DojoOfCool]

I still disagree moisture does continue to escape over the years and the thinner less dense the finish the faster moisture leaves. Even in the video he talks about how more plastic was add to even nitro later and then moving to the poly finish more and more plastic so much more dense slowing down the escape. Finish is a part of a musical instrument sound it affects resonance. Even today they are still searching for the secret to the finish Stradivarius used on his instruments. As a Jazz guitarist I get a lot in wood and how dry it is and the finish used but I started playing in the 60's and lots of Fenders and some Gibsons solid bodies so been talking about this topic with luthiers for a long time. So good to discuss this with you. Thanks

[@cornbobrimlove7892]

@@DojoOfCool It doesn't matter if you disagree. Water does not penetrate plastic. Do an experiment to educate yourself. Put some water in a ziplock bag....seal it up.....wait for 50 to 100 years.....see how much water is still in the bag.

[@michaelquillen2679]

Good video! Straight forward and down to earth! I'm doing a refin of a '63 Fender Musicmaster (previous owner tried to do a refin of the body and botched it badly). I'm going to go with nitro to give it Fender's solid Red Mahogany color of this model in late '63 to try and do justice to this old classic. ON the guitars I build, I use my own home-brewed varnish that can best be described as an an oil-based alkyd. Thanks for the video!

[@howabouthetruth2157]

The highly desirable attributes of nitrocellulose lacquer on acoustic guitars, is the fact it can be applied SO thin ( when done correctly ), that it still looks good, affords protection to the wood, but above all, THE WOOD CAN MOVE/VIBRATE MORE FREELY than any other type of finish. This is where the confusion & myth about "the guitar can breathe better with nitrocellulose" comes into play. The guitar isn't "breathing better".......... instead, THE WOOD CAN MOVE & VIBRATE MORE FREELY......but ONLY if the nitrocellulose is applied properly. This is also why so many boutique builders and/or custom shops within various guitar manufacturers still use nitrocellulose on their finer guitars.......or for special orders where the customer is willing to pay more.

Well for one thing the poly finishes will look more like the day it was purchased than the nitro ones do. So depending on perceptions and ideas 100 years from now that may or may not be desirable.
