Engelmann Spruce

Subtle beauty is king in the world of Engelmann spruce. Rich, complex tonal characteristics jump off the fretboard when played softly. It’s an ideal choice for finger pickers.



Beautiful mid-range clarity with warm inviting highs and tight focused lows. It possesses an ambient acoustic quality that connects the player to the listener by accurately conveying the sound of every nuance and dynamic coming from the player’s hands.


Small Bodies

Have it all with the warm and even tones, comfortability, and masterful construction that define our OO, Parlor, and Grand Concert models.

We Think ‘Inside The Box’

When it comes to building a guitar, there is a big difference between assembly and artistry. If history has taught us anything, it is that there is no substitute for skilled craftsmanship. At Eastman, each instrument is given the attention to detail required to ensure that it reaches its maximum potential. Features such as hand-scalloped bracing and precision tap tuning are just two examples of the way we differentiate ourselves. Considering the outward beauty of an Eastman Guitar, it’s often easy to overlook the skill and artistry applied to the inside of such a fine instrument.


The Beginning

As an accomplished flutist from Beijing, Qian Ni founded Eastman Strings in 1992 after graduating from the Boston University School of Music. He never imagined that over the course of 25 years, the company would grow from a small business operated out of the back of his car into a global maker of musical instruments.

“As a musician, I founded our company with the hope of providing world class instruments for musicians. I personally enjoy the process of working with our luthiers and production team nearly every day to develop new products and improve what we currently manufacture. Eastman is a family business, and I feel very honored to be able to be part of such a wonderful company.” – Qian Ni

These time-honored yet humble beginnings keep us grounded as the Eastman family grows into our third decade of service, supplying the world with the finest instruments. From our skilled luthiers who painstakingly carve carefully selected woods, to the team who hand varnish and age our Antique Varnish Series, our guitar & mandolin craftsmanship is rooted in the same obsession  to build the best violin, violas, cellos, and basses.  We will continue to provide the same responsive service and outstanding products that have helped us emerge as a leader in the world of modern instruments.
