I see SG Basses advertised at 750 to 1,200 but they look identical - any reason why. (Could it be a stockl photo by office staff not knowing the difference.) Is it like the guitar versions where the SG Special is cheaper & the Standard is more expensive. Even the catalogue on the Gibson Web site does'nt help. Has anyone got opinions re' playability apart from neck dive problems. Re-Sale value ? One trick poney or not. Tips, assessment advise. Currently playing an American Jazz. Love it, sometimes too heavey, lacks power output. Love old school sound.
