Overdrive & Distortion
Distortion and overdrive pedals add that much needed crunch, fuzz or drive to your guitar tone. This usually results in more sustain and a richer sound. However not all distortion and overdrive pedals are the same. Some are designed to just push the noise of your guitar a bit, creating a rich warm sound. Others sound much more aggressive tones, these are more suited to heavier genres such as Metal.
