This is a new DigiTech JamMan Vocal Looper XT.
 

Stompbox Looper for Vocalists:
Create live vocal loops on the fly, or even complex multi-layered harmonies with the DigiTech JamMan Vocal XT looper pedal. Plug your microphone of choice into the dbx mic preamp for a clear, powerful vocal sound, then hit the switch when you're ready to loop. You can do plenty of overdubs 10 minutes of total looping time. You can clear your loop anytime without having to start playback, a must for live performance. And because you can use JamSync to synchronize the DigiTech JamMan Vocal XT with JamMan instrument loopers, you can use it to interact with your band in whole new ways.
