Pardon my ignorance... but what do you mean by "the sound of them"? Do they have a characteristic sound?

All strings have their own characteristic sound. Typically, acoustic basses come with bronze phosphor strings like their guitar counterparts, and they're fine if you want a bright sound like a downtuned acoustic guitar. Most people buy an acoustic bass to closer emulate the tone of a double bass however, and for that you will want to use flatwounds or tapewounds.
