The D670 is our ultimate chromatic hammered dulcimer. Building on the popularity of the D650, the D670 adds a feature that players have long been yearning for - the ability to play those low, soul-satisfying super bass notes on the right side as well as the left. The addition of the second super bass bridge to the right of the bass bridge puts those notes within reach for any arrangement that incorporates low bass, and it does this without sacrificing the tonal qualities that are so beloved on the D650. In fact, there is a unique stereo-like effect, with the bass notes seeming to emanate from both sides of the instrument.
Working closely with our design partner, Sam Rizzetta, we developed what we're calling a "dual-density bridge system" to optimize the tonal balance across the range. In the upper register, we're using jatoba, a very dense and articulate South American tonewood, which brings out the clear, ringing bell tones of the high notes. Slightly lighter density Eastern hard maple in the mid and lower ranges facilitates a full, warm, round tone. This combination surrounds the player with a balanced blend of clarity, responsiveness, sparkle and warmth.
The 600 series models have often been called the grand pianos of the hammered dulcimer world because of their large range and deep, powerful sound, and this is in part due to their relatively substantial size and mass. While these models are still portable, it takes reasonable strength to carry them. We've found it helps to distribute the weight between the shoulder strap and the low hand-grip on the case - and limit your walking distance!
Starting in 2011, we began incorporating carbon fiber into the internal bracing of our Chromatic Series dulcimers, improving upon their existing reputation for excellent tuning stability. With a stiffer frame, the tuning stability has gone from excellent to truly exceptional, a benefit that any dulcimer player will appreciate wholeheartedly.
The C600 case is available separately.

The Chromatic Series
Dusty Strings Chromatic Series dulcimers are professional-caliber instruments and are widely regarded as being among the finest hammered dulcimers available. However, this does not mean you have to be a professional to play one! As a beginner, you might be amazed at how quickly you make progress on an instrument that sounds fantastic and is well-made and satisfying to play. Regardless of your experience level, we think you’ll find the sophisticated tone and detailed craftsmanship of the Chromatic Series dulcimers to be well worth the investment.
The tuning scheme is a variation of traditional 5th-interval tuning, where the chromatic notes either replace duplicated notes or are added via extra bridges. We’ve found that it’s no different for a beginner to learn on one of our chromatic instruments than it is to learn on a more basic traditional instrument. More advanced players who are accustomed to traditional tuning will find it easy to adapt and will be delighted by the increased versatility of having access to all the sharps and flats. The chromatic capability opens the doors to musical styles such as classical, ragtime, bluegrass, jazz and rock.
Designed in collaboration with Sam Rizzetta, a highly respected inventor, builder and player of hammered dulcimers since the 1960s, these instruments have his signature asymmetrical design, which places the treble bridge perpendicular to the strings for ease of playing. The internal bracing system is more elaborate and sophisticated than our other models and, combined with the all-solid-wood construction, gives our chromatic dulcimers a resonance, clarity, and depth of tone that is unrivaled.
For the ultimate expressive instrument, we highly recommend the optional damper system. Dampers allow the player to stop the strings from ringing by pressing on a foot pedal, and can be used very effectively to support even more nuanced playing, complex arrangements and interesting voicings. The Chromatic Series dulcimers are now being built with pre-drilled and capped damper installation holes, which will streamline the installation of a damper system whenever it is desired.
The single sound hole is decorated with a hand-carved maple leaf insert, a signature feature of our chromatic line. Contrasting solid-wood binding and delicate multi-layered veneers called purfling add a professional finish detail to the soundboard.

"I absolutely love my new D670! The tonal sound of the new instrument is consistent throughout the entire range. The top part of the range matches the brilliance of the low register. To my ear, the upper register has just the right amount of sparkle; it is crystal clear.
When I received my instrument, it had been shipped across the country and no string was off by more than 5 cents. Amazing! As a professional French horn player, I have a rather low tolerance for an instrument that is out of tune. Previously, I felt the need to tune my dulcimer every day; now, I only tune my D670 once or twice per week. Frequently, many strings are still right on pitch. Hearing that Dusty Strings was [now] using carbon fiber in the structural bracing convinced me that I wanted to upgrade my [older] D600. I have been very impressed with the instrument's ability to hold its pitch and it has been well worth the investment.
Dusty Strings has made remarkable improvements to their already exceptionally fine instruments. I feel like I am playing the hammered dulcimer equivalent of a concert grand piano."
