Just finished the mods on the LP with no problems:
graphtechs (man the ABR-1s are a pain) are on,
Sperzles are on and
I swapped out the 496R/500T PUs and replaced them with 498R/490T.

This took me about 4h start to finish and it was quite an easy job and for spending 30 bucks on tools I figure I saved about 100 bucks on labour.

The only tricky bit was boring out the holes in the headstock and drilling locating holes for the Sperzles. I can now bend 5 half steps on the 12 fret (G string)... with no tuning problems !

The pickups are not quit so hot and are a little more resilient to breaking up, that is exactly what I was after so cool !

All in all I enjoyed tinkering with stuff and the axe is now exactly what I was looking for ! MP3s to follow !
