The owner requested replacement of a couple of pots and unusually requested
the amp be blown out. Being unusual request I enquired what is likely to be
in there requiring blowing out but he seemed a bit cagey.
Inside there are perhaps tens of thousands of precisely 2mm long black
fibres, about human hair thickness. I first thought chopped strand
carbon-fibre but these are less tham 30 Megohm resistance , isn't carbon
fibre conductive?

Could they actually be human hairs? is the owner a trendy short beard
type or a skin head ?

It could be shedded carpet covering off a new speaker cabinet, I`ve seen
it come off bass cabs a bit like that.

Simple now you say it
,its the blue flock covering of the cab, in isolation the fibres look jet
black, pulling some off with pliers and they're all 2 mm long.

greater than 30M that should have been , but as "carpet" fibres a bit
irrelevant know

Some modern carpets do actually contain a percentage of conductive fibres.
