I find it amusing that people usually claim that the New American Standard Bible is very close to the original greek and Hebrew, it seems they dont tell us exactly which Hebrew that is. The New Testament for the NASB is the Novum Testamentum Graece of Nestle-Aland while the Old Testament is Biblia Hebraica Stuttgartensia and the Septuagint.
The Biblia Hebraica Stuttgartensia is based on the Leningrad Codex. Although the Leningrad Codex is similar to the Masoretic the New Testament is definitely not by a long shot the original text used in the King James Version. They did not use the Textus Receptus.
Copyright and trademark to the NASB text are owned by the Lockman Foundation. The same people that own the copyright for the Amplified bible although the Amplified bible is owned by both Zondervan and The Lockman foundation.
