Amidio Inc. has Pearl Guitar (iTunes Link) for the iPad in the iTunes App Store for FREE (regularly $2.99) for a limited time.

The premiere 6-string acoustic steel guitar simulator, Pearl Guitar delivers absolutely stunning sound – the most realistic, lush, organic and warm tone you will hear in the mobile digital domain. In addition, Pear Guitar features Retina graphics, smooth animations and stylish parallax effects animating the strings!

Pearl Guitar is a carefully tuned virtual representation of the legendary vintage 1979 Martin & Co dreadnaught, one of the best acoustic guitars in the world. An optimized 76-Mb sound database is further processed by CascadeEQ synthesis, producing pristine clear stereo audio with a nasty bite of accidental roars, movement hums, string noises and guitar body resonances.

The strumming feels natural; the smooth, dynamic sound varies as you adjust your playing speed. After just a little training, the performance is hardly distinguished from a real guitar. There is also a metronome and a conga drum machine which provide rhythm assistance.

Pearl Guitar offers a novel way to play impressive solo passages – SoloBoard, a button matrix that represents the notes within the detected scale. You can bend the strings and slide between frets, discovering new melodies and progressions.

Record your singing along with the guitar by connecting a headset (like EarPods) or just headphones. Overdub several takes if needed. The minimalistic interface provides instant access to the recording and metronome features. A “Smart Follow” option highlights the next correct chord in the sequence of the song.

The standard version offers 16 most popular chords. Upgrade to Premium Mode to unlock Audiobus, File Manager, and the Chords menu, as well as the ability to make your own songs using the built-in 1000+ chord database (with variations), or your own custom created chords. Songs can be exchanged with the community over Internet.
