I bought this
guitar long time ago, way back in 1994 so this is pretty
much oldie ;) It is still in showroom condition, yet
this Jackson needed some restoration work. I replaced output
jack with original Switchcraft made in USA.. works perfect Next I installed
original Floyd Rose Brass Block
for extra sustain. Does it work?? Well, I don't see much difference :) but by laws of
physics, you add mass to bridge, you gain sustain :)
I also replaced springs. Major job here was fretwork. I did fret leveling, fret crowning and fret polishing.
This took me few days to complete and about 50% of
time went to guitar setup. Finding "sweet spot" on this
guitar was tricky, I mean finding perfect combination
between truss rod adjustment, bridge height and springs
tension.... but this was worth it.. this is one killer guitar now.
