The GS270 feature a double-locking ILT1 tremolo and white dot fingerboard inlays. Similar models were the GSA270DX (which is a twin except for the fretboard inlays) and GSA370QM. All three of these models have a Floyd Rose-style double-locking tremolo and HSH pickup configuration. As of 2016, these three are the only three models in the entire SA series that have either feature.
