Native Instruments has released GUITAR RIG 3.1, a free software update for its digital guitar studio. The new version offers optimized high-precision modeling for improved sound quality as well as several usability enhancements, further expanding the unique power and versatility that make GUITAR RIG an ideal creative tool for modern guitarists and producers. Based on recent engineering progress, GUITAR RIG 3.1 has been equipped with optimized high-precision algorithms, which result in a significantly reduced noise floor for virtual amps and stomp box components with no increase in processor load. This now enables GUITAR RIG to deliver rich, saturated high-gain tones without the usual amount of associated background hiss.
