Removing guitar control knobs

Control knobs can be removed quite easily without recourse to levering with screw drivers or other flat objects with the attendant risk of damage to guitar and control knob.

Simply place a stout cloth under the knob and wrap round until fully enclosed. With care the knob can then be pulled off by virtue of the fact that force can be supplied evenly in line with the spindle and equally all round the knob circumference.
