Features and functionality

    Source

Comparisons

    Source

Mods and upgrades

  • Consider installing a reverse P pickup on models like the Z3/Z7 for a custom sound, especially given the accommodating pickguard design.

    Source

Setup and maintenance

Use cases and applications

  • Achieving the classic fretless "mwah" sound is more reliant on string choice and setup, though the Z7 supports this tonal quality both pre- and post-modification.
