Popping
Popping in stomp box effects is primarily caused by imperfect input and output capacitors (used to block the DC voltage used to power the pedal) that leak. This popping can be fixed by using a pull down resistor (between 100k and 4.7M, exact value is not critical) from the outermost lead of the cap to ground.
