Native Instruments today released GUITAR RIG 2.2, an update for its digital guitar studio. The new version includes three additional modules emulating some of the most sought-after classic guitar effects, and brings compatibility with Intel-based Macs. The new components in version 2.2 include the “Harmonic Synthesizer,” a sophisticated effect that uses the guitar signal to trigger an analog synthesizer circuit; the “Electric Lady,” a faithful re-creation of a classic flanger unit; and the “Phaser Nine,” an authentic emulation of one of the most popular modulation effects in the history of rock music. GUITAR RIG is priced at US$29.
