Features and functionality

  • The Ernie Ball Flex Tuner may struggle to register low B strings on five-string basses, suggesting limitations in frequency detection for extreme low notes.

    Source
  • Headstock tuners, like the Ernie Ball Flex, can be affected by ambient room noise, which may interfere with their ability to accurately tune instruments.

Setup and maintenance

  • Achieving better tuning accuracy for low B strings can involve using the 12th or 5th fret harmonics, as higher frequencies are easier for clip-on tuners to detect.

    Source

Comparisons
