Changes

Speakers are typically rated in wattage, beyond which they will start to exhibit distortion. Some may find it appealing, but I find it difficult to control and too rough sounding. That said, it's rather difficult to achieve. A 4x12 cabinet with 30 watt speakers will require 120 watts of power to distort, while most amp heads provide only 100 watts. Furthermore, even if an amp is run full open, it is [[Choosing_an_Amp#Watts_vs._Volume|not necessarily outputting a full 100 watts]].
