All things must pass. I don't buy backups. If something fails and I can't replace it, I'll do without or get to try new things. My old, first gen Fulltone Supa Trem has chosen a particularly mean time to become unreliable. I like that thing, the speed and hard/soft buttons, the big radio knobs. I may find someone to fix it, but if I can't, I'll get something else. I don't like to cling too hard to any particular things.
