This video promotes the idea that when tuning a distorted guitar, it's crucial to consider the playing style, as the tuning can differ based on whether the part emphasizes attack or sustain. Typically, the transient or pick attack tends to be sharper than the sustained note. For fast, attack-heavy sections, tune to the transient to prevent sharpness during recording. Conversely, for sustained notes, tune to the sustained pitch for accuracy.
This method results in a more unified and cohesive sound. The difference, though subtle, becomes stark when compared to a perfectly tuned MIDI bass, highlighting the importance of this technique for achieving clarity and cohesion in your mix.
