Hi Folks,
A couple of things to be aware of - new skins need
playing in - a lot! So a new drum wont get the best sound for some time to come.
I personally (on experience) wouldn't use dubbin - unless you can get clear dubbin - otherwise the dyes are not appropriate for a musical instrument.
To lubricate the skin use neatsfoot oil. You can find this at any saddlers - but MAKE ABSOLUTELY SURE it is 100% PURE neatsfoot oil. Steer clear of anything marked compound or premium (they add mineral oil to it...mineral oil is a similar stuff to what goes in cars - although its mainly synthetic oils in cars these days!). Neatsfoot oil comes from cattle. Natural product about as close to what is inside the animal's own body as you are going to get.
Indeed Brendan White says lube the skin with natural oil (lanolin is another like neatsfoot).
