If you're a performer, you'll be familiar with "set times". This is the time allowed to you to be on stage, enabling changeovers to be made and events to not overrun (or cut into other performers' sets - very rude!).
This is a device made by Ambient Power that allows a simple display to be at your feet and easy to see. While you're concentrating on the performance, the last thing you need is to calculate times in your head.
A standard timer and a countdown timer, it's all easily settable before the event, just plug in and go. All powered from a standard pedal type 9V power supply.
