Guitar OEM prototypes: approve appearance and playing performance separately

A finish sample and a playable instrument answer different questions. For a private-label electric guitar, retain the build, setup, appearance and playing evaluation against the same identified prototype.

A photograph cannot be the whole approval

A brand likes the colour and outline of an electric-guitar prototype. Before treating it as the production reference, identify what has actually been reviewed: an exterior photograph, a finish sample or the complete instrument in a documented setup. The comments may be valid while sound and playability remain open.

FUJIGEN describes a history of guitar and bass OEM manufacture and work from drying through finishing.[1] That identifies a type of manufacturing enquiry; it does not confirm current capacity or acceptance of this project. Ask the proposed manufacturer about the actual scope and rights to use the requested brand/design.

One prototype can carry several different review records

1Build: identify the instrument, materials and hardware revision
2Appearance: finish, colour and agreed visual conditions
3Playing: setup, sound/electrical checks and evaluator comments

Schematic guitar and review records, not a construction drawing or a setup standard. The image does not prescribe body shape, dimensions or string action.

Keep the build and setup with the sample identity

For this electric guitar, record the body/neck construction, material references, scale/design details, frets, bridge/tuners, pickups, wiring/control specification and finish revision as applicable. Identify which parts and processes are representative of the intended production item and which are prototype-only.

Also retain the string type/gauge, tuning and setup state used for evaluation. Ask who performs the setup and how the agreed condition is documented. Do not adopt a universal action or relief number: the playing requirements and acceptance method need agreement for this model.

Separate the questions, then bring their decisions together

Yamaha describes assembly/adjustment, sound and playability checks, and exterior inspection as different work on its guitars.[2] These are useful distinctions for the enquiry, not a factory specification or OEM offer for the project here.

For a playing review, record the instrument and setup, the playing tasks, relevant amplification/cable/settings, evaluator and observations. Ask which measured checks and which listening/playing judgments will support acceptance. A short phone recording under different conditions is not a controlled comparison by itself.

Prototype review for the hypothetical electric guitar
Review	Keep with the prototype	Decision to record
Build	Sample ID, material/hardware/drawing references and deviations	Which configuration is being evaluated?
Appearance	Finish/colour reference, visible areas and viewing conditions	Accepted attributes, exceptions and remaining corrections
Setup/playability	Strings, tuning, setup state and agreed playing checks	What was acceptable and what needs further work?
Sound/electrics	Pickup/control configuration and listening/test setup	Agreed checks, observations and unresolved issues
Production reference	Accepted revisions, retained sample and change triggers	Who approves each area and the combined release?

Make the retained sample a usable production reference

Resolve comments against the same sample ID and revision. If setup, electronics, hardware, materials or finish changes, ask which reviews are affected and what must be repeated. Keep the decision for each area and the final combined release identifiable; appearance approval alone should not silently release the whole instrument.

Agree how production samples and delivered instruments will be compared with the accepted reference, including packing and handling for the destination. A prototype that plays well does not by itself establish consistent production quality. Other instruments need their own evaluation; guitar setup questions should not be copied to wind, percussion or keyboard products.
