Does mahogany behave like other woods when it comes to weight/density?

[Ken Smith]

I do not agree with your first statement to begin with.

What kind of Mahogany and used where and how on a bass?

With multi layer wood construction like on Smith basses, the answers are not as easy as on 1-piece factory body and neck basses.

So, for a Smith bass, what is your question on woods and what model are you looking at so I can apply an answer to your question?

Specifics make all the difference.

Generalizations do not have specific answers.
