The Takeaways Maybe it’s time for a power brick, or loading the pedals with internal batteries for backup. ----Careful here... Some pedals default to batterie where there is one present... meaning you think you have a back up, but actually you are just running on the batterie. When that dies, as long as long as the batterie is still hooked up, external power wont work. - True story. ---- Also, moving things around regularly to get at batteries - plugging and unplugging - could result in a cable going bad, especially with some of the lower quality or DIY cables. ----A brick is a good solution, especially with a big board, with pedals that are funny about power, and gigging places that have so-so electrical. I've been using a one spot / daisy chain, and not had a problem. From now on I’ll bring a backup handheld tuner. I feel fortunate the tuner on my pedalboard got the job done. ---- Never a bad idea. I have a tuner on my board, but also keep a clip on tuner stashed away in my instrument case. The pedal board, I could play without. A tuner, not so much. Good luck, and keep an eye out for a band that works for you!!!
