Re: heads for maple toms
I'm sure the AC/DC "classic rock sound" you're looking for was probably created using Emperor over Ambassador heads in the first place. It shouldn't be too hard to figure out what heads Phil Rudd uses/used if you really want to concentrate on the AC/DC sound.
I also really agree with Harry's suggestion to try a variety of different heads so you can figure out what is going to work for you. All the advice in the world isn't going to help unless you finally try something for yourself.
