Introduction Description DEMO MODEL: This instrument has been opened and typically used by an artist or group at a clinic or performance event (i.e. a State Educator show, or Industry Trade show booth.) The instruments, with very few exceptions, are in original packaging. All DEMO models instruments still carry the full manufacturer s warranty – but at a lower cost to compensate for the limited usage. All specifications and details are identical to the brand new versions. The Adams *Demo* Professional Generation II Hammered Copper Timpani feature the new Patented Balanced action pedal mechanism as used on the Revolution Series with adjustable spring tension. With this mechanism, the pedal action is smooth and offers the player an extended tuning range with a familiar balanced feel and adjustability via a tension knob. Hammered Copper provide the best price-quality ratio. Compared to the Polished Copper you pay a little more, but you get a tone that is more focused and direct.The Professional Generation II bowl is suspended from a single flange chrome plated steel ring supported by strong struts for maximum sustain and projection. New large commercial grade double-locking, double-wheel swivel casters and stylish base legs with a wider stance, offer the drum more stable support while being played, and safer maneuverability. The Professional Generation II drums also feature an integrated locking 3rd wheel assembly on the player s side with two permanently affixed wheels and brake allowing for nearly effortless instrument moving.
