Safe removal of a tone control from a loose shaft.

[bass_dinger]

My treble tone control on my active Washburn XB500 is loose. 

Having inspected it, I see that the whole pot is loose.  I think that I need to tighten the bolt that fastens the post to the body.

However, I cannot remove the tone control from the shaft of the pot.  There is no grub screw to fasten the knob to the shaft, so, it may be a friction fit.  However, it does not want to move! 

Any advice?

Use a small spoon to lever the knob up; perhaps one spoon on each side.  Put a cloth down first to protect the top of the bass.

Or feed the edge of a thin duster or old T-shirt under the knob and wrap it/twist it around a touch so that you are getting even tension all around then pull firmly but steadily the twisted fabric directly upwards.

Love the colour of the bass, btw.

Both methods mentioned above will work

Thank you!  I do sometimes doubt my choice - green basses are uncommon  enough for me to wonder if they are generally disliked.  However, I decided long ago that I personally like it enough not to mind.

 

I will try to Two Spoons method tonight.  And tomorrow, I will start a thread headed "Safe attachment of a tight tone control . . . "

It worked!  Thanks for the sound advice.
