Turntablism
Stylus
The stylus is the small shaped tip that rides the record groove, mounted on a cantilever inside the cartridge. It is a wear part: the tip erodes with use and eventually starts damaging records rather than reading them.
In practice
A worn stylus damages records and sounds fine until it does not. Replace on hours played, not on how it sounds.
Manufacturers quote lifetimes in the hundreds of hours and scratching consumes them far faster than playback does. Keep a spare in the bag — it is the cheapest fault to fix at a gig and the one most likely to happen. Clean the tip with a proper brush from back to front, never side to side, and clean records rather than letting the stylus do it. If one deck is misbehaving and the other is fine, swap the styli before you suspect anything else; it takes twenty seconds and it is usually the answer.

Why it matters
A worn stylus is the most common cause of problems people blame on everything else. Distortion on loud passages, mistracking, skipping on records that used to be fine, timecode dropping out on one deck — all of it points at the tip long before it points at the deck or the mixer.
The dangerous part is that it degrades slowly enough that you adapt to it. A tip loses its shape over hundreds of hours, sounds gradually worse, and every day sounds much like the last, which is why replacement should be on a schedule rather than a judgement.
Frequently asked
How often should a DJ replace a stylus?+
On hours rather than on feel, because it degrades too gradually to notice. Manufacturers quote lifetimes in the hundreds of hours, and scratching gets through them considerably faster.
Can a worn stylus damage records?+
Yes. A tip that has lost its shape no longer sits correctly in the groove and abrades it instead, which is permanent and affects every record you play afterwards.
Why is one deck dropping out on timecode?+
Suspect that deck’s stylus first. A worn tip reads the control tone poorly, and swapping the styli between decks tells you the answer in twenty seconds.
Related terms
Cartridge
A cartridge converts the stylus’s movement in the groove into an electrical signal. It mounts to the tonearm, holds the replaceable stylus, and its design decides how securely a record tracks under handling.
Tracking force
Tracking force is how hard the stylus presses into the groove, measured in grams and set by the counterweight. Too little and the stylus leaves the groove; too much and it wears both the tip and the record.
Record weight
A record weight is a heavy disc placed over the spindle to press a record flat against the platter. It improves contact on warped records and adds mass to the platter, which resists small speed variations.
Timecode vinyl
Timecode vinyl is a record pressed with a control signal instead of music. DVS software reads that signal to work out where the needle sits and how fast the platter is turning, then plays a digital track to match.
