Compact geometry maximizing playability and tension balance.

Concision Series

The “Headless” line, with a Head.

3.5° shallow break angle with a Fender-style drop-down.

Like the Foundation its built on, the graduated angles allow the nut to participate more uniformly across all strings.

More downward pressure on the highs, Less on the lows, for balanced articulation, and uniform response.

Contact

Guided by Balance

A 3.5° break angle paired with a Fender-style drop


Similar to the Foundation Series, it features graduated break angles, moving naturally from low to high strings. The result is a Uniform, and responsive playing experience , with a slightly tighter feel than its counterpart.


Increased downward pressure on the treble strings

Reduced pressure on the bass strings

Ergonomic


It features individual bridge saddles that minimize string-to-string crosstalk, enabling stable performance and making this the only Contriver series to offer 8-string variants.


Available In 

6, 7 or 8 String

Set Neck or Bolt on


Ideal For

Alternate tunings

Extended ranges

Multiscale layouts

Body Material

Materials are selected for how they behave as part of a mechanical system, not for species reputation.


Pairings are evaluated by mass, stiffness, compliance, and damping to ensure predictable outcomes across scale length, tuning, and neck construction.


Wood choice refines response — it does not define the instrument.


Available Shapes

Signature or Echo


Important Context
Each option exists to maintain mechanical balance within a defined geometric system.

If a material choice would require post-build correction, it is not used.


No material listed here is intended to “add tone”

Neutral / Balanced Core

Even mass distribution and moderate stiffness for broad compatibility.


Northern Ash
Alder


These materials provide a stable baseline with minimal bias toward attack, decay, or frequency emphasis. Their mechanical properties allow geometry and scale length to remain the dominant factors in feel and response.


Use When

You want maximum predictability

Compatibility across multiple scale lengths

Even response without compensation elsewhere in the system

Firm / Defined

Higher stiffness-to-mass ratio with reduced compliance.


Roasted Ash
Swamp Ash


These selections increase structural rigidity and reduce energy loss at the body interface. The result is a faster transient response and more immediate string feedback, particularly under higher tension.


Use When

Longer scale lengths

Lower tunings

Players who prefer a tighter, more immediate feel

Systems where added stiffness supports clarity

Warm / Damped

Increased internal damping with controlled energy transfer.


African Mahogany
Walnut
Black Limba


These woods absorb slightly more vibrational energy, reducing edge and smoothing attack without compromising structural integrity. They are used to moderate stiffer necks or extended-scale geometries rather than to introduce coloration.


Use When

Counterbalancing rigid neck or fretboard constructions

Seeking a more forgiving response under the fingers
Managing excess stiffness without adding mass

Structured / Composite

Distributed stiffness through multi-piece architecture.


Ash Core + Black Limba Wings


Composite layouts allow stiffness and damping to be placed where needed rather than averaged across the body.mThis enables finer control over response without increasing overall weight or relying on species extremes.


Use When

Additional control is required without changing geometry
Fine-tuning system behavior for extended scales or specific neck builds
Visual contrast without functional compromise

Top Material

Top woods primarily influence surface response and feel, while supporting visual character.


The core body wood remains the main driver of the instrument’s mechanical foundation.
 


Important Context

Top wood refines behavior at the interface with strings and neck.
Mechanical behavior is defined by body geometry, neck construction, and overall system stiffness.

No top is used to “color” tone; its role is structural and aesthetic.


Carved Top - Included

Bent Top - Additional Upcharge

Neutral / Reinforcing

Minimal damping, maintains body’s intrinsic response.


Northern Ash

Roasted Ash

Flame Maple

Roasted Flame Maple

Quilted Maple


These woods provide a stable, mechanically consistent surface without altering the foundational behavior set by the body. 


Use when you want the top to reinforce the instrument’s natural stiffness and energy transfer.

Warm / Softening

Slight increase in damping for smoother surface response.


Black Walnut

Flame Claro Walnut

Koa

Redwood Burl


These selections slightly modulate surface compliance to reduce transient sharpness at the top layer. 


This does not alter fundamental energy transfer, but can help balance stiffer necks or extended scale designs.

Dense / Reflective

High stiffness, firm surface for precise string response.


Macassar Ebony


This dense top produces a mechanically firm interface, increasing note definition and snap at the string contact point. 


It is paired with body woods that allow the energy to flow naturally through the instrument.

Visual / Character Tops

Primary function is aesthetics; surface behavior tuned by underlying body and neck system.


Spalted Maple

Maple Burl
Poplar Burl


These selections are chosen for visual impact while the core body wood and neck geometry handle mechanical response.


Any damping or stiffness effect is incidental and secondary to structural design.

Neck Material

Neck material governs stiffness, stability, and tactile response. Its mass, compliance, and construction directly influence how the instrument behaves, shaping string response and overall playability.


Stiffness, scale length, and geometry define performance.

Neck Material refines it.


Construction Options

Bolt-On Neck – Included

Set-Neck Construction – Additional Upcharge
 

Neck wood and construction type combine with body geometry and break-angle design to define the platform’s behavior, ensuring predictable response across all builds.

Neutral / Reference

Balanced stiffness and predictable response across scale lengths.


One-Piece Quarter-Sawn Maple

Three-Piece Quarter-Sawn Maple
 

Ideal for players seeking a familiar, consistent feel with neutral mechanical behavior.

Firm / Controlled

Increased stiffness for precise string control and defined attack.


One-Piece Roasted Maple

Three-Piece Roasted Maple

Five-Piece Maple + Roasted Maple

Five-Piece Roasted Maple + White Maple
 

Best for longer scales, heavier string gauges, or extended-range instruments, providing stability and clarity without introducing excessive rigidity.

Warm / Compliant

Slight damping for a smoother, more forgiving hand feel.


One-Piece Sapele

Three-Piece Sapele + Maple

Three-Piece Maple + Sapele
 

Useful when pairing with dense fretboards or stiffer body cores 

helping maintain a comfortable, consistent touch.

Dense / Rigid

High stiffness with immediate, defined string response.


Five-Piece Maple + Wenge

Five-Piece Wenge + Maple
 

For players who need maximum control and articulation, particularly for aggressive or technical styles.

Fretboard Material

Fretboard material affects tactile response, note definition, and subtle stiffness at the point of contact with the strings, refining the feel and articulation of the instrument.


Important Context

Overall behavior is still governed by neck mass, stiffness, scale length, and geometry.

Fretboard choice adjusts the interface, not the foundation.


Additional Options
Scalloped Frets – Additional Upcharge
Multi-Scale Scallop – Additional Upcharge

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.

Balanced / Neutral

Even response with controlled attack and broad compatibility.


Figured Chechen

East Indian Rosewood

Ziricote


Use when maintaining consistency across the system without emphasizing extremes

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.

Scale Lengths

Scale length affects string excursion, stiffness, and feel under the hands.
String gauges are adjusted to maintain comparable tension across all options, so differences are driven by length and diameter, not overall tension.


Single Scale Options

6 String and 7 String


25.75″

More string movement under the fingers. Softer feel with greater excursion.

26.375″

Even balance between movement and control. Neither stiff nor loose.

27.00″

Reduced excursion and firmer feel. More controlled response on the low strings.
 

Multi-Scale Options

Graduated feel across the set. Tighter lows with more compliant highs, without uneven tension.


27.00" - 25.75"

6 String and 7 String


27.25" - 25.75"
