Ultralight and surprisingly tight


The Treeline is a unique, ultralight bass with a surprisingly tight sound. Weighing only 3,000 grams (5-string version) its weight is extremely low. The Treeline design is derived from our single-cut Powerline bass. The single-cut construction allows for optimal energetic transmission of the string vibration, resulting in tight and dominant lows. Therefore, the low B of the Treeline is well-defined and solid as a tree.

Maximum playing comfort


The Treeline stands out for its playing comfort. Due to the smooth neck body joint the neck is easily accessible up to the 24th fret. Furthermore, the Treeline has an asymmetrical neck profile − thicker under the B string and thinner under the G string. This ergonomic design provides a highly comfortable, natural grip.



Full-bodied sound with crisp highs


The Treeline features a quarter-sawn, set-in neck. This construction combines the full, compressed sound character of a neck-thru bass with the typical transparent highs of a bolt-on.

Fully custom made


Each Treeline is a unique instrument of which literally only one exists. We’d be proud to build this bass entirely to your personal preferences, using all the desired woods and a top quality pickup, electronics and hardware. Naturally, this custom bass is available as a 4-, 5- and 6-string, fretless and fretted, and (no extra charge) left-handed.
