A 12-Fret Dreadnought with a "Custom" Character
The SDR-42S belongs to the Custom series and embodies a highly sought-after spirit: the 12th fret dreadnought neck joint. This design, historically associated with traditional instruments, favors a generous tone and immediate response. Combined with premium tonewoods and a natural finish, it clearly targets guitarists seeking an expressive instrument that is both powerful and nuanced.
For Which Guitarists and Styles?
Thanks to its dreadnought size and solid woods, this guitar is especially suited for intermediate to advanced players looking for dynamic response under the fingers. It excels in folk, bluegrass, country, acoustic pop, and vocal accompaniment. When fingerpicked, it maintains clear definition while providing a solid low-end foundation.
The Sound
The solid Adirondack spruce top delivers a crisp attack, great precision, and especially a wide dynamic range: the harder you play, the more the instrument "opens up" without distortion. The solid Indian rosewood back and sides enrich the spectrum with complex harmonics, deep lows, and a generous sustain, highly appreciated in open chords as well as melodic lines. The ebony fingerboard adds a sense of clarity and clean articulation, while the bone nuts enhance vibration transmission and note precision, particularly on pick attacks.
Recommended Compatible Accessories
To get the most out of this folk format, a set of steel acoustic strings (bronze or phosphor bronze) is perfectly suited. A capo and an acoustic guitar humidifier are also good daily companions, especially to preserve the solid woods. The guitar comes with a soft case SSC-D for transport.
