Q: What are the benefits of a multiscale?
Ergonomics: guitarists learn to move hand along the neck perpendicularly. If you relax your wrist then the multiscale corresponds much better with the hand position on the neck.
Tension: you have a longer scale for rhythm and don’t have to use extra thick strings. Also for soloing you have a more comfortable shorter scale.
Tone: with a longer scale lower notes sound clearer and more distinct, without any mudiness. With a shorter scale the higher notes sound full and rich, avoiding any harsh qualities of a monoscale baritone.
Tuning: overail, the guitar has a more stable tuning across the whole fretboard.
