Potentiometers for guitar volume and tone controls. Push/push operation allows access to unique wiring schemes (for example, split or parallel operation on humbuckers) by pushing on the top of the knob, it will either spring up or sit low to switch between the switch connections of the potentiometer. Many players find these to be preferable to push/pull potentiometers due to the ease at which they're used.
These are the same size as USA sized potentiometers, and are of high quality.
