SG
SG is a guitar manufactured by Gibson. It is most definetly NOT a "poor man's" Les Paul! What kinda motherfucking bullshit is that? It is as prone to accidents as any guitar, as a guitar can not cause an accident itself, it needs human assistance. If you dont want the headstock to snap, then buy a decent strap and dont drop the damn thing! Thats basic common sense.

The SG is famous for its superior access to the top frets, light weight (although the sound certainly isnt lightweight!), comfort and playability. Noteworthy Gibson SG players include: Tony Iommi (Black Sabbath), Pete Townshend (The Who), Angus Young (AC/DC) and me.

The Gibson SG is a monster of an instrument, with that powerful, rich Gibson sound, dangerous distortion and serious sustain!

sg
1)
A group that roam the area of east sydney. They think they own the streets and the entire network or "league" as they call it.

Rumour has it, that much like the Universe, SG was created with a "Big Bang", this is officially named the "Worm Fart". Which upon release has the innate property of raising the level of dopamine in all SG members within it's radius. Inducing a freedom ritual.

They have a multitude of gang signs including the straight face, the freedom totem and the notorious SG symbol. These however always hold an aura of transience. The greatest example of the continuously changing nature of these greetings is the SG fistbump. There are currently two acceptible fistbumps including the untouching walk-away bump and the rock v paper bump. Both derived from the youtube-famous JimmyTatros.

To become a SG member, the individual has to attend the freedom initiation ritual which is held in one of the founding member's crib. Every one of SG's rituals are somewhat confidential and there is currently no solid eveidence of them ever happening.

These scandalous people believe that they are hardcore but in reality they are just a Study Group.

SG
The Gibson SG is a very beautiful Guitar. Played by many greats, and often called a poor mans Les Paul, it is actually the Les Paul's replacement. (The Les Paul was so popular they had to reissue it.) Notable Gibson SG players include Jimi Hendrix, Tony Iommi and Angus Young. There are many different models you can obtain, including the Angus Young Signature SG, which is the AC/DC guitarists personal favourite.
