Bright: This voicing mode emphasizes the higher frequencies, resulting in a brighter and more articulate tone. It can be useful for adding definition to clean tones or cutting through a dense mix.
Normal: This mode typically represents the amplifier's default tonal character without any additional modifications. It provides a balanced sound that is suitable for a wide range of playing styles.
Vintage: This voicing mode emulates the tonal characteristics of classic tube amplifiers from a specific era. It often adds warmth, depth, and a touch of natural overdrive to the sound.
Modern: This mode typically provides a more aggressive and high-gain sound, often associated with modern rock and metal guitar tones. It emphasizes the mid-range and low frequencies, resulting in a thicker and more saturated tone.
Contour: This voicing mode usually adds a mid-scoop to the amplifier's tone, emphasizing the high and low frequencies. This can create a more scooped and "V-shaped" sound, enhancing the clarity of the low and high ends while reducing the prominence of the midrange.
Fat: This voicing mode typically enhances the low frequencies, making the amplifier's sound thicker and warmer. It can be useful for adding fullness to clean tones or for achieving a more powerful crunch sound.
The specific effects of a voicing button on a guitar amplifier can vary depending on the amplifier model and its circuitry. Some amplifiers may offer additional voicing options or incorporate variations of the above-mentioned modes. Experimenting with different voicing modes can help guitarists find the optimal tone that suits their playing style and musical preferences.
