According to the story in Bass Player Magazine, Guitar Center owns the rights to the name, as well as the contract of George Grexa, who re-engineered the new Acoustic 360. Those were formerly held by Samick.
"In 2006 after a three-year process Grexa landed the rights to build and sell American-made Acoustics worldwide. Within a year, however, Samick had sold the Acoustic name (and Grexa's contract) to Guitar Center. Grexa's company, GPG/Acoustic USA (www . acousticbassusa . com), owns the rights to produce Acoustic products, and Guitar Center must approve anything GPG does with the name "Acoustic" on it.
So, they're sorta the same thing, kinda, a little, well, vaguely … One wonders if they'll be merging the two lines into one group with a budget-friendly line of products and a top-of-the-shelf line, similar to the business model Fender uses with Squier.
