Turntable Problem

[Matty]

I have a technical problem. I am a beginner DJ and I am having a problem with the sound from my needles. I have the Ortofon Nightclub needles and when I play my records everything sounds great except for whenever a synth or string type sound comes in there is a volume or speed change, almost like a whinding noise. It is a consistant sound and it does it on every record. Can anyone help?

Have you balanced your tone arm and set your anti-skating properly???

[Matty]

Yes. The tonearm is balanced and all other adjustments are set perfectly.

might need new needles or the motors have had it

does this happen on both decks or just one??

tbh if the motors was going you would prob hear like a weird whirring going up and down in pitch mainly on synths and you would find it very hard to mix - pitch always going out of sync etc
