Used Guitar Inspection Generator

What this tool is for

Generate a repeatable pre-purchase condition inspection. Inspection tools preserve visible evidence and untested areas. They separate condition notes from diagnosis, valuation, authenticity, and warranty claims.

Use it when you can describe the current state and need a defensible next check. It is not a shortcut around inspection: preserve the starting state, change one variable, and verify the result under the same conditions.

Before you begin

Bring a tuner, flashlight, short known-good cable, clean amplifier or interface, and measuring rule. Ask permission before removing covers or adjusting anything.

• Use a stable, tuned instrument unless the page specifically investigates tuning.
• Name the physical reference, unit, and test condition beside every important number.
• Keep the original measurements so any reversible change can be returned to baseline.

Input guide

Instrument

identifies the record so its result is not attached to the wrong instrument or work order.

Asking price

provides a measured or counted input; confirm the allowed range and repeat the reading before relying on it.

Neck condition

classifies an observed condition; choose “unknown” or “not tested” instead of guessing when available.

Fret condition

classifies an observed condition; choose “unknown” or “not tested” instead of guessing when available.

Electronics

classifies an observed condition; choose “unknown” or “not tested” instead of guessing when available.

Structure

classifies an observed condition; choose “unknown” or “not tested” instead of guessing when available.

Notes

captures the exact observation, list, or requirement that the result must preserve.

Input labels describe evidence, not targets. A placeholder demonstrates format only; it is never a recommendation for a particular guitar.

How the result should be read

Use “not tested” whenever access or conditions are missing. A failed item identifies uncertainty for negotiation or inspection; it is not a remote diagnosis.

Read priorities from top to bottom, but stop as soon as new evidence contradicts an earlier assumption. Save or print the result ticket with the entered conditions so another person can reproduce the decision.

Method and logic

The report separates identity, visible structure, neck and frets, hardware, electronics, acoustic noises, amplified behavior, and measured setup. Observations remain distinct from inferred repair cost.

The page keeps calculation and diagnostic claims deliberately bounded. Display rounding improves readability, while the underlying logic uses entered values; descriptive branches report relative tendencies and the evidence needed to confirm them.

Worked example

A used electric priced at $700 shows fret wear under strings 1–3, intermittent output when the jack moves, and no visible neck crack. Record each fact and price a professional assessment instead of labeling the guitar “good” or “bad.”

The example demonstrates reasoning, not a universal setup specification. Substitute real measurements and repeat the final test before accepting the next action.

Assumptions and limitations

Serial numbers do not prove ownership or authenticity. Hidden repairs, truss-rod range, internal moisture damage, and intermittent faults may escape a short inspection. The generator is not a warranty.

Instrument design, service history, measurement error, and player technique can outweigh a calculator or checklist. Where manufacturer instructions exist for the exact hardware, use those instructions and record the revision consulted.

Safety and stop conditions

Stop for abnormal resistance, cracking, heat, odor, electrical sensation, moving wood or joints, a measurement that cannot be repeated, or any step that would remove material without a confirmed cause. Secure strings and stored mechanical energy before hardware work. Refer structural, fret-cutting, mains-powered, or uncertain repairs to a qualified technician.
