The left handed version of the Yamaha RGX 612S is quite similar to the Yamaha RGX 612A but it lacks the Active Pickups. The Yamaha RGX 612S features the same HSS pickup configurations but has 2 passive Yamaha Alnico single coils and 1 Yamaha Ceramic humbucker. The controls are 1 Master volume knob, 1 tone knob for the single coils and a second one for the humbucker which also functions as a push/push coil split. The 1987 version had a Yamaha RM II tremolo while later versions feature the Yamaha RM Pro.
