Huw Price of Guitar & Bass magazine wrote about the Little Sister
"It’s not simply a visual thing. The Little Sister really does feel like an old guitar, albeit a factory-fresh one."
So how to you may a new guitar sound, feel, and look old?
It's actually pretty simple - by using the same materials and replicating the same techniques from the 50's without any shortcuts.
We use nitrocellulose lacquer to seal, paint, and coat our guitars. Nitro has been the mainstay for decades since it was first developed in the 1920s. When nitro first came out it was much faster drying than other options, but since the mid 60's poly has become the standard for its faster dry time. But poly is much thicker, and that affects the wood resonance (and not in a good way).
Nitro is not an unbreakable chemical bond like polyester and polyurethane. Nitro is not a cocoon, permanent and unmoving, wrapped tightly over your guitar’s body. Nitro is evaporating and leaving your guitar always. A thin finish to begin with gets thinner and thinner with time, allowing the wood molecules to literally dance to your music.
The process, however, is a bit longer. We apply 3-4 sealer coats, 6 clear coats, having each coat dry for a day and add 2 weeks drying time after the final coating.
