By aligning damper movement with the front-to-back motion of the chime tubes when struck, damping response has been notably improved. It is now easier to stop the extended sustain of the chime tubes at the most musically appropriate time.
A swivel prevention function has been added to the caster locks. Furthermore, the YCH7018 now features height-adjustable casters. If the chime tubes are not properly centered in the damper they can touch the damper felt, reducing sustain and deadening the tone. Adjustable-height casters make it easy to level the instrument so that the chime tubes hang away from the damper felt.
Flexible Tube Arrangement
A full complement of damper holes is provided in the sharp/flat chime tube row, allowing any arrangement of chime tubes to be used. All available spaces can be used for a total of 21 tubes, if desired. Complete layout freedom is provided even when special-order chime tubes are used, since the position of the low C tube is not predetermined.
Note: The natural-note row of the YCH7018 does not provide sufficient height for longer chime tubes such as the YCHT7049A YCH7050A#, and YCHT7051B, so those tubes should be hung on the sharp/flat row or on a separate YCHS7006 stand.
