  • The World of Fretless Guitar

    Flatter opens up expressive techniques like:

    - Quarter tones and "in-between-the-frets" phrasing

    - Natural vibrato, smooth glides, and unique voicings

    - Access to Eastern scales and microtonal textures

    From Indian and traditional Middle Eastern music to experimental rock, fretless guitar is a powerful tool for

    sonic exploration.

  • Why Bassists Love Going Fretless

    Think Jaco Pastorius, Bill Wyman, and countless others.

    Fretless bass delivers warmth, nuance, and tone you can't get anywhere else.

    Flatter gives you a practical, affordable way to play fretless - without needing a second instrument.
