Loose knob caps/worn out buttons.......Not really a problem because machanical parts always work loose and wear out over time. All of my old analogues are stuck together with glue

! But just out of interest ....has anyone here had any problems with knob caps, buttons or noisy modwheels.
The knob cap on my Virus KC worked loose (and eventually came off after 2 days)......but this kind of thing doesnt bother me....we dont live in a perfect world
