Narrow Bass Flatter – 1.50” (38-39mm) Nut Width

Turn your 34" scale bass into a fretless bass without removing the frets. The Narrow Bass Flatter is designed for 4-string basses with a 34" (864 mm) scale and a nut width of approximately 38–39 mm, making it ideal for many Jazz Bass-style instruments.

Guitar Flatter is a removable fretless bass conversion system that clips over the fingerboard, creating a smooth playing surface while leaving the original frets untouched. It installs and removes in minutes, with no permanent modification to your bass.

Recommended Before Installation:
For the best performance, we recommend setting your bass with slightly higher string action before installing the Bass Flatter. This helps ensure clear notes, better sustain, and the best possible fretless playing experience.

If your bass is already set up with moderate string action, no further adjustment may be necessary.
