How to value synths, keyboards and drum machines

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.
