Being able to control the gain on your signal is the most significant part of making your guitar playing sound as heavy as possible. The huge range of gain control is what sets the G3 apart from the competition. It's perfect for Metal, Punk, and the most extreme music styles you can think of. The G3 from Revv has very simple controls so you can dial in the perfect tone with ease. A must have for those who err on the extreme side of music.
