Thinking back, my musical life (such as it is) would not have started if other bands had not generously let me use their gear.
As a typically teenager I thought I knew it all, and I lacked the social skills and experience to say 'please' and 'thank you' properly.
I know I must have used gear in a way that made its owners wince. But...they let me, and almost without exception encouraged me.
Like most of us on this forum, I've worked long and hard to get the gear I've got now. But, its only stuff.
