Guided by Behavior
Similar to the Refraction Series, it features a single break angle but instead integrated through carving methods rather than scarf joints.
The 5.8° headstock angle sits at the lower end of the Foundation Series’ graduated break-angle spectrum, easing downward pressure on the highs and mids while keeping the lows comparative for a looser, more expressive feel in the upper registers.
- Treble strings are expressive, yet compliant
- Bass strings feel firm, yet elastic.
This makes the Bass VI / VII ideal for alternate tunings, extended ranges, and multiscale layouts

Body Woods
Materials are selected for how they interact as a system, not for species alone. Pairings are guided by mass, stiffness, compliance, and damping to maintain predictable behavior.
Neutral / Balanced
Even response, broad compatibility across scale lengths and neck constructions.
Northern Ash
Alder
Use when: you want predictability, consistency, and an even mechanical response.
Firm / Defined
Increased stiffness and clarity with a more immediate attack.
Roasted Ash
Swamp Ash
Use when: longer scales, lower tunings, or players who prefer a tighter feel.
Warm / Damped
Slightly increased damping with a smoother attack and relaxed mids.
African Mahogany
Walnut
Black Limba
Use when: aiming for a more forgiving response or counterbalancing stiffer necks and fretboards.
Structured / Composite
Three piece constructions tuned for stiffness distribution and visual contrast.
Ash Core + Black Limba Wings
Use when: additional control over response is needed without increasing overall mass.
Top Woods
Top woods primarily affect surface response and feel while contributing visual character. Core body woods remain the primary driver of the instrument’s foundation.
Neutral / Reinforcing
Minimal damping, reinforces the body’s natural response.
Northern Ash
Roasted Ash
Flame Maple
Roasted Flame Maple
Quilted Maple
Warm / Softening

Spalted Maple
Maple Burl
Poplar Burl
These tops are selected for visual impact and are paired with body woods that maintain structural and tonal balance beneath the surface.
Carved Top - Included
Bent Top - Additional Upcharge
Neck Woods
Neck wood selection plays a major role in stability, stiffness distribution, and tactile response. Wood choice is used to fine-tune feel rather than alter the platform.
Neutral / Reference
Even stiffness with predictable response across scale lengths.
One piece Qtr Sawn Maple
Three Piece Qtr Sawn Maple
Use when: a balanced, familiar feel is the goal.
Firm / Controlled
Increased stiffness and focus, especially beneficial for longer scales and extended-range instruments.
One Piece Roasted Maple

Use when: prioritizing clarity, stability, and low-string control.
Warm / Compliant
Slightly increased damping with a smoother, more forgiving feel.
One Piece Sapele
3 Piece Sapele+Maple
3 Piece Maple+Sapele
Use when: counterbalancing dense fretboards or firmer body cores.
Dense / Rigid
High stiffness with pronounced definition and a more immediate response.
Five Piece Maple+Wenge
Five Piece Wenge+Maple
Use when: maximum control and articulation are required, particularly for aggressive playing styles.
Bolt On - Included
Set-Neck - Additional Upcharge
FRETBOARD
Fretboard materials influence attack, tactile feel, and high-frequency response. Selection is guided to complement the neck and body system.
Immediate Attack / Defined
Fast attack with clear note separation and minimal damping.
East Indian Ebony
Gabon Ebony
Macassar Ebony
Use when: clarity, articulation, and precise response are the priority.

Warm / Forgiving
Softer attack with increased damping and a smoother feel under the fingers.
Bocote
Pale Moon Ebony
Use when: counterbalancing stiffer neck constructions or longer scale lengths.
Bright / Elastic
Snappier feel with a slightly more elastic response.
Quarter-Sawn Flame Maple
Flat-Sawn Blistered Maple
Use when: adding immediacy and tactile feedback without excessive stiffness.
