The GSA370QM features a double locking ILT1 tremolo bridge, a quilted maple top and Ibanez pickups in an HSH configuration. Similar models were the GSA270 and GSA270DX. 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.
