Mounted on a gibson les paul studio, I installed it in less than thirty minutes.

Just put it directly below the bridge, removing the strings and the bridge, we set the sensor is reset and the bridge over the ropes. Finally, we regulate the height of the sensor quickly and it's good!
result my guitar is intact I can remove the GK3 if I want without the instrument to be drilled or dirtied by adhesives! and the sensor works very well.
on the other hand, some guitars may need to resort to adhesives provided with the apparatus of the type of bridge of the instrument ...
