Wow, another fascinating story.
I initially thought "what could be interesting or unique about a guitar amp?". Then I read the amp story and immediately tied it to the unique sound of of the songs I grew up with. (Queen was my favorite band as a young teen. I had their albums on vinyl at home and 8 track for family trips. It was years before I realized the significance of their name -- I now wonder what my parents thought when I mostly listened to Queen and the Rocky Horror soundtrack.)
I didn't think the guitar story could come close, but it was almost as fascinating. I have a new level of respect for a band that made their own instruments, and worked with their 'flaws' to produce innovative, memorable music.
