Defect volume pot VR09


I have a problem with the volume control on my Roland VR09 Combo. I get a clean sound when the volume control is full (all to the right). When the volume is at 12 o’clock or less, there is a high frequency noise, not loud but noticeable. What’s annoying is that I can’t set the volume to zero, it stays almost the same below 12 o’clock. Do you think I should replace the rotary potentiometer? In that case I looked at this one:
Rotary potentiometer, 50KBx2.
(Part #1873)
Do you think this is the right one?
Thank you for your help!
