Choosing The Right Guitar AmplifierMay 18, 2023
What Guitar Finish Best Suits You?
It usually boils down to Nitrocellulose (nitro) lacquer vs. Urethane guitar finishes. Some say that one is too thick and robs tone, while the other too thin and fragile, but lets the guitar resonate.
Is this true?
What is the Difference?
The difference in the two are night and day.
Urethane is dried by chemicals and can be ready to buff out in just a few days. Nitro needs to air dry to release its solvent and it’s usually a good bet it will take about thirty days to dry.
Urethane is far more durable, scratch resistant and easy to work with. Nitro is very fragile and can be damaged easily or even cracked by cold weather. Nitro can have a sticky feeling to your hands even years after it is painted whereas urethane does not.
You can achieve an equal amount of gloss with either.
Is There a Difference in Tone?
The Question of Tone is Subjective
Sometimes a person hears what they want to hear. You would be hard pressed to hear any difference in tone in any of our guitars at Old South Custom Guitars.
The reason I think there is little difference is because I believe what matters is the thickness of finish. I believe that plays a major role in how “alive” the guitar sounds. When we use urethane, we keep it as thin as possible. It is all a matter of what you are looking for in your guitar.
Durability may be what you are looking for over vintage correctness. Either way, when done right, you can hardly tell a difference in the two.
So Which One?
For me it's simple. On a vintage recreation or restoration, I want lacquer.
Because it's what they used in the fifties and sixties and it's the only way to get the proper aging of those finishes.
For a more modern guitar, I much prefer urethane for its long lasting shine and durability.
Need help deciding? Just go and play a lot of guitars with each type of finish and see what feels best to you. After all, what fits you is all that really matters.
