SIGMA GUITARS Sdr1-45

An "All Solid" Sigma Designed for Moving Upmarket

With the SDR1-45, Sigma emphasizes a lutherie-oriented approach: the "All Solid" label indicates a construction in solid woods, a choice appreciated for how the instrument evolves and opens up over time. The SDR1-45 model fits into an upmarket logic, with a presentation and design focused on musicality, stability, and playing pleasure, whether at home, in rehearsal, or on stage (with microphone pickup).

For Whom and Which Styles?

This acoustic guitar is particularly suitable for intermediate to advanced guitarists who want to upgrade to a livelier, more nuanced, and more responsive instrument than a laminated construction. It adapts very well to styles where dynamics matter: folk, acoustic pop, chanson, country, as well as accompaniments rich in harmonics. Motivated beginners can also find an excellent foundation here, especially if they are looking for a "long-term" instrument.

The Sound

An all-solid construction generally provides a more sensitive touch and better translation of nuances: the sound reacts more to the attack, with a more natural "breathing" sensation. The solid top drives projection and articulation, while the solid back and sides contribute to depth, sustain, and stability of the bass and harmonics. Depending on the setup and string gauge, the instrument can remain clear in open chords while retaining body for arpeggios and melodic parts.

Recommended Compatible Accessories

This Sigma SDR1-45 comes with a Sigma SSC-D case, recommended to protect the instrument from shocks and temperature variations during transport.
