Valuation by gear type

For guitars and basses, start by identifying the exact model, series, year and country of manufacture.

Then check:

• fret, neck and truss-rod condition;
• electronics, pickups and controls;
• cracks, breaks or structural repairs;
• bridge, tuners and hardware;
• modifications and included original parts;
• original case or other relevant accessories.

On common instruments, playability and overall condition often matter more than minor cosmetic wear. On vintage or collectible models, originality and provenance can become much more important.

Always compare the same configuration: two guitars with the same commercial name can belong to very different series and value tiers.

For an amplifier, verify the model, revision, power rating, configuration and, where relevant, production year.

Valuation should account for abnormal noise, channels and controls, valve condition, documented servicing, transformers and replaced components. For cabinets, check the speaker model and condition, impedance, wiring and cabinet integrity.

On vintage equipment, original transformers and speakers can materially affect price. On recent models, reliability and the cost of potential repairs often matter more.

Weight and fragility also affect market liquidity: an item that is difficult to ship may have a different local value from prices seen in broader markets.

With pedals and effects, identifying the exact revision is important, especially when the same model name has remained in production for many years.

Check switches, pots, jacks, displays, MIDI or USB where present, power requirements and abnormal noise. Note modifications, repairs and the presence of Velcro or baseplate changes, which may matter to some buyers more than others.

Original box, manuals and accessories can matter more for limited editions, discontinued products or collectible units.

For models that remain readily available new, always compare the real retail price: immediate availability and warranty can cap the maximum realistic used value.

Synths, keyboards and drum machines require both mechanical and electronic checks.

Test displays, keys, velocity or aftertouch where present, encoders, faders, buttons, audio and MIDI ports, memory, slots and the power supply. Identify hardware revisions and installed expansions.

For digital instruments, obsolescence and parts availability can become important. For analogue or highly sought-after models, documented servicing and component condition can increase buyer confidence.

For large and heavy keyboards, also consider transport and local collection. A perfectly working instrument that is difficult to ship may have a smaller realistic buyer pool.

For an acoustic drum kit, identify the series, configuration, shell sizes, finish and country or period of production.

Check shells, bearing edges, hoops, lugs, hardware and signs of moisture or warping. Cymbals, snares and hardware can have substantial standalone value, so do not automatically treat a mixed kit as one homogeneous product.

For electronic drums, test the module, pads, triggers, cables, power supply, stands and component compatibility.

Package size and shipping can materially affect demand. For complex kits, it is often useful to value the main components first and then assess any bundle discount or premium.

In recording and live audio, value can change quickly as connections, drivers and digital standards evolve.

For interfaces and controllers, check compatibility with current systems, transferable licences where relevant, ports, encoders and power supplies. For mixers and power amplifiers, test channels, outputs, fans and abnormal signals. For monitors and microphones, consider matched pairs, capsules, suspensions and physical condition.

With digital products, a perfectly working older unit may have limited value if software support has ended. High-quality analogue equipment may be less affected by age when maintenance and demand remain strong.

Real-world operation and current compatibility belong in the valuation alongside the model name.
