The JamMan Express XT is DigiTech's answer to the compact looper hype, with more recording time, stereo input/output and better LED control. Like other small loopers, it has a single footswitch that lets you record, play, overdub, undo, and redo a single loop. But it stands out from the crowd with its longer 10-minute total loop time and dedicated LED lights that let you know if you're recording, overdubbing, or playing. These extras make it easier to use and allow for worry-free looping when practicing, brainstorming, or even performing. Another nice feature of the JamMax Express Specifications: Total Loop Duration: 600 seconds Loop Memory Slot: 1 Audio Quality: 24-bit A/D/A - 44.1 kHz sampling rate Input: 2 x 1/4" (stereo) Output: 2 x 1/4" (stereo) Power: 9V battery, DC adapter (optional) Additional feature: JamSync Dimensions: 4.5" x 2.75" x 2" Weight: 0.6 lbs.
