Oh, I have a lot to learn, particularly about the older Marshalls. I've learned a lot in a fairly short time but there's much I don't know. I subscribe to the Japanese philosophy of ownership: A durable product may last centuries. Despite the ordered destruction by General MacArthur at the end of the war with Japan in WWII, of thousands of Japanese swords, many of which were 500 years old or even older, many of those ancient swords still survive today and most are in excellent condition. Some are as pristine as the day they were made, due to being cared for and maintained regularly. The Japanese philosophy is that we are just one of a string of people to possess a durable product. We last decades, but the item of interest can last many centuries with care. You are not its only owner, but just the owner for now. It is our responsibility, should you accept it, to be a custodian of that item who does no harm to it, and allows the next generation to appreciate it as it was originally made, as much as possible. When you realize that someone else is probably going to have that old amp after you're gone, it might make you ask yourself what state you want it to be in when the next owner gets it. My attitude is the opposite of the "throwaway culture" that seems to define most consumerism today. I appreciate products that are built to last. I take care of them and try to keep them in good condition.
