The DEEP VINTAGE II presents an option for using deeper sounding heads on contemporary drums without the loss of resonance. Aquarian’s multi-ply vacuum tuning process eliminates dead air? spots and adds depth and durability to these two 10mil plies. The slightly thicker vintage coating is for more than just a classic look; it slows the vibration of the head and results in a lower, warmer tone with a softer feel. The DVII bring the truly authentic sound of traditional calfskin heads to the modern drum and drummer, but with better performance results and they look as good as they sound!
