Components and soldering: look for consistency without treating every repair as suspicious

On an older effect unit, switches, jacks, potentiometers and power connections may have been repaired after years of use.

Inspect soldering, wiring, components and signs of replacement, but also ask whether the intervention is consistent with normal maintenance.

A documented professional repair may be preferable to an intermittent original component. From a collector perspective, however, the replacement should still be disclosed.

If the circuit has been modified to alter gain, EQ or bypass behaviour, describe that separately from maintenance.
