Tama TW100 Tension Watch

While these are not a replacement for a good set of ears they can help speed up the tuning process and get you in the right ballpark with the suggested settings they give. Perfect for the novice drummer who has yet to master tuning and much better than guess work. Having the tension of the skin equal at every lug is important and this will help achieve that. Better results are achieved with a good quality drum and skin also. One feature it is missing is a spacer to keep the watch exactly 1cm from the drum rim, which the ddrum version has.
