This is the guitar simulator that converts an iPad into an electric, acoustic, or bass guitar tutor. An iPad (not included) docks into the body of the full-size guitar simulator and a free app displays guitar strings that aspiring musicians can strum and fingerpick to generate resonating guitar sounds through the built-in speaker. The guitar simulator's stringless fret board has 84 LEDs that illuminate to show aspiring guitarists where to place their fingers to play proper notes and chords and the app allows musicians to add distortion, reverb, and flanger delay to their compositions. The app recreates sound from an acoustic, electric, or bass guitar, includes 10 practice songs, and allows musicians to play along to music in their iTunes library. The headphone input enables practice that won't disturb others and the unit adjusts to accommodate left- or right-handed guitarists. Compatible with iPad, iPhone, and iPod running iOS 5 or later. Includes four AA batteries. 36" L x 12" W x 1 1/2" D. (3 3/4 lbs.)
