Did anybody mention "Road worn" yet (I know, really...).
The question is whether:
a. the bass has been gigged "on the road" and has received natural wear and tear,
b. it has been dragged along a road behind a vehicle and so is genuinely road-worn, or
c. the poor defenceless instrument has been attacked by a numpty with something sharp or abrasive in the belief that knackering it will add value?
