Strings, I think are almost universally accepted as 'consumables', that is, they have a certain life span after which necessitates replacement where also the cost of replacement is often less than the cost of a would-be refurbishing. Are bass cabs 'consumables'? Forget for a second about the notorious GAS that we all inevitably acquire. Have those old cabs you want to sell actually deteriorated? If so, what do you consider the life span of a bass cab? What lifespan would you be agreeable to as a consumer? What else? Do basses actually have a cyclical typical duty cycle? I would tend to think,once weve found an actual bass that we love and enjoy that any amount of refurbishing would be worth the expense.
