My guess is an 84.
Im not comvinced these were factory black hardware.
There wasnt a custom shop for the focus line & no other foci sported black at the time..
Call it coincidence.
Looking at the link doc provided, that one even has a black neck plate which appears to be original.
Seems like the 4000 might be a bit of a dark horse. No pun intended.
Also just to clarify, JivRey, you definitely have a Focus because it says Focus on the headstock. The F series would typically have a truss rod cover to identify F-1000 or whatever it was and it has the large Kramer logo with the shrinking letters. Regardless, nice axe you got there.
Sounds like you got bit by the same bug we all have. Enjoy the guitar and accept the sickness
