Bought as replacement pickups for Ibanez GSR205B. Install was (relatively) easy, insulation paint in the slots made them about 0.3mm too narrow for EMGs (5-10min job with wood file, no power tools required).
Wiring process was easy, instructions are very clear and all required hardware is provided. Reused old audio plug (soldered connections), old pickup screws (black - EMG provided are silver) and old spacing foam/springs (not provided with EMG pickups).
Entire operation took less than hour (removing strings, filing slots, fitting pickups, connecting all the wiring, soldering (old plug), arranging wires, putting strings back...).
Huge upgrade over stock Ibanez pickups, clean and balanced tone across the range.
