First time in 10 years. I went to a gig yesterday and my combo amp wouldn't power up. Fortunately it wasn't too far from home, so I was able to go get my big rig and make it back in time for an only-slightly-late start. But obviously there will be times when that won't be possible. Now I'm thinking about switching to a 1x10 cab and a micro head, so I can bring a backup head. Practical or paranoid?
