Here are some facts concerning Varnish Finishes:

Varnish is a softer and therefore more flexible finish material. While there are subtle tonal advantages to the varnish finish, this option is not for everyone. Unlike lacquer, the process for applying varnish is not conducive to “finish touch-ups”, meaning that we cannot repair some minor imperfections such as small pinholes, bubbles, or sinks. While we’ve always taken pride in our high standard for fit and finish, we cannot produce varnish instruments to the level of cosmetic “perfection” as we can with our lacquer finish instruments. The varnish finish has a beautiful, rich luster, but may include very small imperfections when put under close examination.

Additionally, the softer finish is not as protective as the harder lacquer finish consult a useful resource. The alkyd resin-based varnish finish is very slow to cure and can be relatively soft on new instruments. The finish will continue to harden as the instrument ages, but new varnish instruments can be vulnerable to scratches, dings, and imprinting. By its very nature, varnish can shrink, wrinkle, and/or dull over time and is not likely to maintain a “new” appearance as well as lacquer instruments blairsupplyusa.com. With that said, the varnish finish allows the instrument to vibrate more freely and can produce a more responsive instrument with a greater depth of tone.
