Evolution Steel Strings features an iconic, Martin D16R steel string acoustic guitar recorded in stereo with top-notch mics and preamps in 24-bit, 48 khz for the best tone and fidelity possible. While most acoustic guitar sample libraries are sampled using only one mic, we used stereo micing, for a more natural tone, and also adjustable stereo width. The superior construction of the guitar used resulted in minimal buzzing on even the hardest hit notes.
