From DW:
The California Custom Shop is like no other custom drum workshop on Earth. Starting with only select, responsibly harvested woods, a variety of shells configurations are crafted to order.
In experimenting with different exotic woods as alternate shell making materials, DW’s Custom Shell Shop discovered that in addition to the different tonal qualities inherent in every unique type of wood, alterations in grain direction can also greatly influence sound. In a VLT shell, the outermost and innermost plies run vertically, rather than a traditionally horizontal configuration. The vertical grain places less tension on the shell, allowing it to vibrate more freely, resulting in the lowered fundamental pitch. For those players who prefer a lower overall tone while still maintaining maximum resonance and attack, VLT can be ordered as an option on all Collector’s Series Pure drums.
Our popular Vertical Low Timbre shell technology has just been improved. This 9-ply shell delivers attack, sustain, and maximum low-end response.
