Adams Concert Vibraphones feature precision graduated bars in either Anodized Silver or Gold, along with the durability and stability players demand in the studio and in the clubs. Concert Series instruments now feature the Adams Apex Frame — with its unique minimalist side pillar design, integrated shore braces, and ultra-strong two-piece crossbar, Apex instruments are quick to assemble and easy to transport, allowing performers at any level to achieve their peak performance. The Concert Series Vibe 12-volt motor runs safely on 110 or 220-volt power with the special converting power adaptor, completely eliminating the possibility of any electrical hazard. Clean mounted controls allow the player to choose whether the fans stop in either the open or closed position. The motor speed is fully adjustable from 25 to 150 rpm with intuitive fader control. A newly advanced, foot-operated precision dampening mechanism allows both damper and rail height adjustments, allowing each player to custom configure the feel of the instrument to their exact playing style. The damper also utilizes a new supreme quality felt material to achieve truly silent damping. An optional Long Pedal Extension Accessory converts the swivel pedal to a full-length pedal board.
