I use this toolkit to change the strings and adjust the height of the pickups. Small kit, doesn't take up much space.

very beautiful tools.........................

Excellent "first aid" kit!

The tools are of good quality but the manual, in English, is incomplete: in terms of string height adjustment, only the low E string (bass or 6-string) is mentioned. We would have liked a summary table of the adjustments specific to each type of instrument according to the manufacturer's recommendations.
