The 3-octave Pro-Vibe was designed for peak performance and easy portability. Hand tuned aluminum bars and seamless arched and mitered resonators produce a rich and resonant tone. The adjustable, swiveling sustain pedal offers precise feel, and the variable speed motor is insulated for quiet operation. An adjustable damper bar and a distortion-free bar suspension system assure exact pedaling control. With lustrous gold satin-plated bars, the Pro-Vibe makes a stunning impression on the concert stage or playing field. The All-Terrain Cart features 10-inch pneumatic wheels for smooth transportability.
