Tone Settings, EQ, and Mixing Approaches【RADWIMPS・Akira Kuwahara】
The core of Akira Kuwahara’s tone crafting lies in his mastery of “spatial utilization” and “sound placement.”
His tones are carefully positioned in specific frequency ranges that don’t interfere with other instruments, with particularly excellent mid-range EQ adjustments.
The amplifier EQ typically emphasizes the midrange slightly while keeping the presence control moderate, resulting in non-harsh highs and warm, musical tones.
This approach ensures that the guitar maintains its character while serving the overall musical arrangement.
For spatial effects, careful attention is paid to the mix balance of reverb and delay, often employing send-return methods to create “depth” in the sound.
Guitar positioning varies depending on the song, with left-right panning and multiple take doubling being commonly observed techniques.
During recording sessions, the foundation typically starts with clean tones lightly treated with reverb or chorus, with boosters or preamps added as needed to create three-dimensional soundscapes that highlight picking nuances.
The recording approach often involves capturing multiple performances and carefully blending them to create a fuller, more complex guitar texture.
