Routine checks and preventive maintenance
A method for spotting wear, loose parts, oxidation and abnormal behaviour before they become larger problems.
Many problems begin with visible or mechanical signs before becoming audible.
Look for loose screws, moving jacks, kinked cables, cracked plastics, oxidation, rubbing parts, controls whose travel has changed and obstructed ventilation. Compare the condition with what you remember or with earlier photographs.
A few minutes of inspection after transport or heavy use can prevent continued operation of an already damaged part.
An auxiliary input, effects loop, MIDI port, secondary switch or headphone output may remain unused for months.
During periodic checks, test functions that are not part of daily use. This can reveal oxidation, intermittent connections, discharged batteries or lost settings before the function is actually needed.
Record anything you could not verify. “I do not use it” does not mean “it definitely works”.
There is no single maintenance calendar suitable for every item.
Gear used on stage every night needs more frequent checks than equipment kept in a studio. Perspiration, dust, transport, vibration, humidity and operating hours change how quickly strings, batteries, connections and mechanical parts deteriorate.
Build a routine from actual use: frequent quick checks and deeper inspections when changes appear or after periods of intensive use.
