hey. yea yamaha sells them, you need not go to their industrial building. just go to the plaza singapura shop.
yea and for the overtones. yea you could use o rings. or moon gel. some people just tape cloth to their snare. try with the cloth so see if its better first. and i suggest why dun you try retuning the whole snare. maybe then you dun even need to change the heads. good tuning can make a lousy kit sound great. so yea try it. you could find alot of tuning resources online. youtube has many videos too
