Можно в сравнении с популярными гитарными деревьями типа липы, краснухи и т.д.

Наверняка украинская черная сосна примерно равна американской черной сосне. Black Pine в Америку была завезена из Европы! Но думаю, что разница ы условиях произрастания все-таки сказывается. В какую сторону - не берусь судить.
Вот их "родная сосна" (Southern Pine) - достаточно твердое дерево. Тут товарищи сравнивали американскую сосну с другими (жирный шрифт мой): Says Eddie Pearce, European Marketing Director, American Softwoods: "These independent tests have finally proven that American Southern Pine is the strongest softwood with excellent resistance to indentation. It is an all-round timber ideal for both external and internal structures. And when treated and kiln-dried, it has no rival in terms of strength, versatility and durability."

On impact bending Southern Pine was "significantly stronger than all other species under test". The hardness tests (for resistance to indentation) assessed the radial and tangential surfaces of each softwood. Southern Pine was the densest material and was shown to be 51% denser than European Whitewood and 14% denser than New Zealand Pine, its nearest rival softwood species.

On the tangential face, Southern Pine again came out top for hardness rating, although Chilean Pine and New Zealand Pine were close behind. The most significant difference was the comparison with European Whitewood, with Southern Pine being 80.8% harder.
