scientific, and has to do with the voltage sensitivity of each pedal. the guitars volume control is a voltage device. if you were able to consistently maintain it's position the entire night and the next time you play it, you would have the same results as the OBEL. but since you cannot, that volume alters the voltage to the effects and produces different results each time you touch the volume control, on purpose or inadvertently. with the OBEL, you produce a consistent volume each and every time. this allows you to get consistent results from your effects and that is what you are hearing. your fight with a consistent result from your rig should essentially be over, and aside from an occasional adjustment here and there, it should become set and forget.
