Owner Insights

Build quality

    Source
  • The bass is notably heavy, weighing over 11 pounds, which might be a concern for older players or those with back issues.

Features and functionality

  • The side dots are positioned between the fret lines, which can be confusing for players accustomed to placing fingers on the lines.

    Source

    Source

Mods and upgrades

  • Owners refrain from changing stock hardware, fearing it may negatively impact the tone, although string changes are common.

    Source

Comparisons
