I. Core Criteria for Electric Bass Grading

1. Wood Selection Determines the Fundamental Tone

(1) Body Wood Types

• Alder: Balanced tone, suitable for various music genres.
• Ash: Bright and clear tone, ideal for funk and pop music.
• Mahogany: Warm and heavy tone, perfect for rock and metal.
• Basswood: Pronounced midrange with excellent cost-performance ratio.

(2) Neck Wood

• Maple: Fast response and bright tone.
• Mahogany: Longer sustain and warmer tone.
• Carbon Fiber-Reinforced Necks: Highest stability and warp resistance.

(3) Fingerboard Wood

• Maple: Bright tone, commonly found in Jazz Bass models.
• Rosewood: Warm tone, often used in Precision Bass models.

2. Pickup System Influences Tone Performance

• Single-coil: Clear and bright tone, suitable for funk and pop.
• Humbucker: Full and thick tone, ideal for rock and metal.
• Active Pickups: High output with low noise, great for heavy music.
• P/J Hybrid Configuration: Combines the tonal characteristics of both pickup types.

3. Craftsmanship Affects Playing Experience

• Neck Joint Types: Bolt-on vs. Set-neck vs. Neck-through — each impacts sustain and resonance.
• Fret Crafting: Stainless steel frets offer higher durability.
• Bridge System: Influences tuning stability and sustain.
• Electronics Design: Quality components reduce signal loss and noise.
