12-String Acoustic Guitar

A guitar that has 12 strings, 3 bass strings, 3 tenor strings, and 6 octave strings that pair with each string. Each octave string is tuned to the same key as it's other string, but also remain an octave higher. They create a rich and powerful sound that pairs good with loud and forceful singing, and is commonly used by buskers and professional performers. All tunings of course work with these, but the common and most effective tunings are standard tuning, and are commonly tuned to key of D, C, and B, tuning.

A famous and very talented performer, Lead Belly, used a 12-string acoustic guitar as his signature instrument, and usually had his guitar tuned to Standard B tuning for a wide range of songs and notes. He one of the most influential guitar players, and introduced many people to the 12-string.

Acoustic Gangsta

Ah-Koo-Stick Gang-Stah.

A white person (sometimes with dreadlocks) and an acoustic guitar, preforming for friends or for a large crowd, acoustic versions of popular or underground gangsta rap songs. Usually pretty fucking hilarious.

Did you hear Nina Gordon's "Straight Outta Compton?" She is such an Acoustic Gangsta!

or

That Acoustic Gangsta got his ass beat by a bunch of black guys for sayin' "Nigga" too much... guess doing a cover of "Damn it feels good to be a gangsta" was a bad idea.
