Part One: As Received
This Ibanez GIO HSH S-style guitar came in all the way from Temerloh for an overhaul and various upgrades. For starters, it lacked labels indicating its serial number or country of origin. Fair enough, as a previous owner might have removed these labels; or they might have worn off over the years.

The stock pickups were two generic humbuckers and a single coil, all in working condition. The pickup and control cavities were also shielded with conductive shielding paint; a definite plus point. Yusri, the current owner, had also brought along a Seymour Duncan humbucker to be installed in the bridge position.

A previous owner had upgraded the electronics with CTS pots and a Switchcraft output jack; but retained the stock PCB-based five-way switch. The really shocking part was that he/she did not bother to upgrade the control knobs, and simply jammed the existing 18-spline knobs onto the 24-spline CTS pot shafts. You can see the results in the sixth picture below. Readers, DO NOT ever try to force 18-spline knobs on 24-spline pots; or vice versa. You have been warned!
