Purpose and description
Enable an AI agent to recognise a bass guitar, assess its playable condition and compatibility, and determine suitable setup, playing and maintenance actions.
In the musical-instrument sense, a bass is an instrument designed to provide a low register within an ensemble or instrument family, commonly supplying bass lines and harmonic foundations.
It can be Identify the bass variant and document evidence supporting its classification.; Tune its strings to a verified target using an appropriate pitch reference.; Select replacement strings compatible with its scale, hardware and intended tuning.; Assess action, relief, intonation and unwanted noise before proposing setup work.; Connect its output to compatible amplification or recording equipment and test onboard controls.; Perform supported routine care and flag structural or electrical faults requiring repair..
Distinguishing features
Has strings extending along a neck and fingerboard to a body, with vibrating length set by stopping the strings or playing them open.
Is identified through its intended tuning, string arrangement and construction as a bass guitar; string count or body silhouette alone cannot distinguish it from a guitar.
May have frets or an unfretted fingerboard, so the absence of frets does not by itself identify a double bass.
Electric variants convert string vibration to an electrical signal through pickups; acoustic variants have a body intended to radiate useful acoustic sound.
Represents an instrument kind rather than a low-frequency sound, a bass part in a score or an external bass amplifier.

Characteristics
- Instrument variant
- electric solid-body; electric hollow or semi-hollow body; acoustic; electro-acoustic; other; unresolved Determines how sound is produced and what amplification or inspection steps are relevant.
- String and course arrangement
- string count, course count and grouping of strings into courses Distinguishes independently played strings from doubled courses and constrains tuning and replacement choices.
- Open-string tuning
- ordered note names with octave identifiers and reference pitch in Hz Makes intended register explicit and supports tuning and string-selection decisions.
- Scale length
- nominal vibrating length in mm or inches, per string for multiscale instruments Affects string compatibility, tension relationships and setup.

- gauge by string in mm or inches; winding construction; material; winding length; end fitting Supports compatibility checks with the scale, bridge, nut and intended tuning.
- Playing geometry
- neck relief and string action in mm at explicitly named measurement locations Allows repeatable assessment of playability without treating one setup as universally correct.
- Intonation deviation
- cents at specified stopped notes relative to the intended pitch Helps identify setup or string problems after open-string tuning is established.
- Pickup and onboard electronics configuration
- pickup types and positions; passive or powered circuitry; control functions; bypass capability if verified Determines signal behaviour, power requirements and diagnostic steps.
- External signal connection
- instrument output connected to a specified cable and compatible receiving input Supports safe, functional connection and separates instrument faults from downstream faults.
- Playing readiness
- ready; playable with limitations; setup required; repair required; unassessed Summarises whether the instrument can support the intended playing task.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 14 findings · 24 questions.
Bass identity and register Establishes which bass instrument is represented and how its strings provide the intended musical register.
The registry label is ambiguous, and neither appearance nor string count alone establishes bass-guitar identity.
Instrument sense and family
Separates the provisional bass-guitar interpretation from neighbouring meanings and instrument families.
Bass-guitar classification
Record evidence for the instrument-family assignment and retain uncertainty where the registry label is insufficient.
- What registry provenance establishes whether bass means bass guitar, double bass or another thing? provenance
- Which construction and intended-use features distinguish this instrument from a guitar or double bass? boundary
Strings, courses and tuning
Describes string grouping and intended open pitches without assuming a particular string count.
Intended pitch layout
Record each string's course membership and intended open pitch, including octave and reference pitch.
- How many strings and courses are present, and which strings share a course? measurement
- What open pitch is intended for each string, and what source supports that tuning? definition
String path and playing surface Describes the physical path that supports string vibration and the surfaces used to select pitches.
Bass string compatibility and playability depend on scale geometry, anchoring and fingerboard construction.
Scale and string fit
Connects vibrating lengths and hardware dimensions to replacement-string requirements.
Compatible string envelope
Record scale geometry, anchoring route and string specifications needed for a physically compatible set.
- What is the nominal scale length for each string, and is the instrument single-scale or multiscale? measurement
- Which winding lengths, gauges and end fittings fit the nut, tuners and bridge arrangement? action
Neck and pitch contact
Captures the neck and fingerboard features that govern stopping positions and string clearance.
Fingerboard and fret condition
Record fretted or fretless construction and local wear affecting string contact or pitch production.
- Is the fingerboard fretted or fretless, and what markers or fret positions define its playing layout? definition
- Where are worn frets, grooves, raised edges or other contact-surface defects observed? measurement
Sound production and output Tracks acoustic radiation, pickup conversion and the instrument's electrical interface where present.
Bass variants differ in whether they require an external signal chain and in how onboard power or controls affect output.
Acoustic and pickup paths
Identifies how string vibration becomes audible sound or an electrical signal.
Sound conversion configuration
Record the body's acoustic role and each fitted pickup's type, location and selection behaviour.
- Does the instrument rely on acoustic body radiation, pickup output or both for its intended use? definition
- Which pickups are fitted, and which strings or body vibrations does each capture? definition
Controls, power and connection
Defines the operating requirements of fitted electronics and their interface with external equipment.
Usable output state
Record control functions, verified power requirements and connection details needed to obtain a usable signal.
- What does each control do, and which functions require a battery or another power source? definition
- What output connector and receiving input are required, and how can their operation be tested? action
- Does inserting a cable switch onboard power, and what documentation confirms the behaviour? provenance
Bass setup and care Connects measured playing behaviour to setup decisions, routine care and repair needs.
A bass can be correctly identified and tuned while remaining difficult to play, poorly intonated or mechanically unsound.
Action, relief and intonation
Assesses playing geometry and pitch behaviour under a stated tuning and string set.
Setup against playing requirements
Record repeatable measurements and symptoms relative to the intended technique and manufacturer guidance.
- What action and neck relief are measured, at which locations and under what tuning? measurement
- At which stopped notes do pitch deviations, buzzing or choking occur under the intended playing technique? measurement
- Which adjustment sequence is supported for this bridge and neck design? action
Wear, faults and intervention
Distinguishes routine string and hardware care from faults requiring specialist repair.
Condition-led maintenance
Record string deterioration, unstable tuning, loose fittings, structural defects and intermittent output with appropriate next actions.
- Which symptoms originate in strings or instrument hardware, and which remain attributable to the external signal chain? boundary
- What routine care is supported by the instrument's materials and documentation, and which observed defects require repair before further use? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

What the second pass must settle
- Does registry provenance confirm bass guitar, or does this entry represent double bass, fish or another sense of bass?
- If bass guitar is confirmed, does the registry include acoustic, fretless, extended-range and doubled-course variants within this entry?
- Does an existing world model already own the confirmed concept and require this registry entry to link to it?
- Which manufacturer or specialist sources should establish variant-specific string compatibility, measurement procedures and adjustment limits?
- Which standards or certification requirements, if any, apply to particular powered bass variants and their supplied electrical accessories?
