The System II and III tremolo systems use a height adjustable locking nut.
The System II tremolo system was designed by John Page, Chip Todd and Charlie Gressett.
The System I tremolo system uses a behind the nut string locking mechanism and was manufactured by Gotoh.
The System II and System III bridges have individual string height and individual string intonation adjustments.
The single coil pickups used in the Contemporary models have a DC resistance which is approximately 5.6 kΩ.
The Contemporary models that use a TBX tone control use 500 kΩ volume pots and use 0.022 µF tone capacitors.
