on hardware my understanding is that industry is the closest thing we now have to the computer boom before personal computers. Off the shelf products sold by retailers are pretty poor and not cheap with acceptable margin, often get hacked by demanding users on fixed budgets. High performance stuff requires actual hardware expertise and artisan craft, very expensive, low volume, made to order, and the margin is probably close to minimum wage. It's an industry thats run on passion, my pessimistic take is guitar insurance is likely much easier and far more lucrative.
