2. Body & Finish Craftsmanship (Gloss Ocean Blue Burst Finish, Solid Body, Mahogany Body Wood)

  1. Body Shape: Classic asymmetrical streamlined solid bass body with ergonomic curved wings for comfortable holding during performance. Solid mahogany body provides warm rich resonance, deep focused low end and sensitive dynamic response, perfectly supporting various bass techniques such as Funk slap & pop, rock rhythm lines. The glossy ocean blue burst finish gradients smoothly from light cyan to deep ocean blue, clearly showing natural wood grain, with premium luster for stage shooting and product display. All body edges are finely rounded to remove sharp corners and reduce fatigue during long-time standing performance.
  2. Finish Technology: Multi-layer glossy ocean blue burst baking varnish technology, bright full surface with strong adhesion, scratch-resistant and fade-resistant. The glossy coating preserves original acoustic performance of timber without suppressing body vibration, restoring pure warm resonance of mahogany. The finish is stable and durable, resisting abrasion during long rehearsal and tours. The fresh gradient color scheme matches all kinds of stage styles.
  3. Side & Bottom Structure: Consistent glossy ocean blue burst finish on entire body. Precise internal weight calibration achieves balanced weight distribution to relieve fatigue for extended playing. Output jack position is reserved for direct connection with amplifiers for live amplification.

3. Neck & Fretboard Configuration (Maple Neck, Rosewood Fretboard, 22 Frets, Shark-Fin Shell Inlays)

  1. Neck Material & Playability: Solid maple neck with glossy finish, rigid stable structure with excellent moisture-proof and anti-deformation performance, reliably supporting high string tension of bass strings. Designed with vintage rounded C-shape profile with balanced thickness, great for slap & pop and fast scale playing. Maple neck delivers transparent vibration and enhances midrange response, making bass lines clear and outstanding, easy to adapt for beginners and professional musicians.
  2. Fretboard Details: High-density rosewood fretboard, hard and wear-resistant, stable under different humidity. Resists indentation from frequent string bending, vibrato and slap techniques. Equipped with 22 metal frets with fully chamfered polished edges for smooth sliding without scratching hands. The fretboard is decorated with iconic shark-fin shell inlays, easy for fret positioning under dim stage lighting, inheriting classic retro bass design aesthetics. Rosewood naturally softens harsh high frequencies for balanced warm tone.
