Starting with the knobs, the rear PU has been replaced with SEYMOUR DUNCAN's SH5 (with a narrower bobbin spacing compared to the string pitch), and the pegs have been replaced with GROOVER's lock pecs. 　　

Also, the bar bridge has been replaced with one made by WILKINSON, but the set screw for adjusting the octave pitch is missing. 

The truss rod cover on the head side is also missing.
