Ash is a medium-hard somewhat heavy wood with an open grain structure. This makes it a bother to finish, but the striking grain patterns under a clear-coat are well worth the effort. Otherwise famed as broomsticks and baseball bats.
This is my reference for guitar setups - a Japanese "E-series" Squier Stratocaster from the early '80s. This was an era when Fender-America was not doing their best work, while the Japanese models were superb.
