The Endpin of my double bass keeps creaking when I play some certain notes.

enter image description here

Is there a way to make it stop? It's pretty annoying sometimes. Someone told me to cut it off, but I don't really want to do that, because I might want to sell it some day and I think the buyer would want the whole Endpin.

Take it to a reputable repair shop or luthier and find out what's really going on. Endpins are replaceable. –  Carl Witthoft Nov 12 '13 at 15:17
    
Just the endpin or the whole bass? –  Shevliaskovic Nov 12 '13 at 15:18
    
The whole bass, so the fellow can determine the source of the noise. –  Carl Witthoft Nov 12 '13 at 15:24

Your Endpin appears to be creaking by way of sympathetic resonance or vibration. As you noted certain notes cause the creaking while others do not which indicates that there is resonant frequency that the Endpin is reacting too.

The best advice would be to have you take the instrument to a respected luthier for inspection and possible repair. I say 'possible' as this might be the case of a badly designed instrument which may make a repair impossible.

In the meantime, a simple workaround other than removing or cutting off the Endpin, would be the opposite. That is add more mass to the pin to change its resonant frequency. You could do this a number of ways and still make this modification reversible so you do not make any permanent changes to the instrument.

One way to do this would be to use a C clamp but add felt to the edges that engage the Endpin, or a Spring Clamp (be sure that the teeth are coated with soft plastic), or a Handscrew Clamp.

If your Endpin is removable then by all means try something lighter or heavier with the same diameter to see which item is less likely to creak.
