Product title: Digitech EQ Effects Pedal, Regular (JMEXTV)
Product description: The DigiTech JamMan Express XT is the most full featured compact looper on the market. Its simple, small, and very sophisticated. With true-bypass, 10 minutes of stereo looping, Silent Clear, and Jam Sync the Express XT is a perfect looper for your pedal board or addition to your JamMan XT looping set-up. Its incredibly easy to use with dedicated LEDs clearly showing its status. The Express XT works right out of the box using a 9V battery (included) or you can power it with an optional power supply. When looping, timing is everything; Jam Sync takes care of it. Jam Sync automatically synchronizes with another Express XT or JamMan Solo XT allowing you to create independent yet perfectly synchronized loops. Using Jam Sync you can build a custom multi-track looper or build loops with your band. The Express XT is the first looper to feature DigiTech s new Silent Clear feature. The Express XT automatically recognizes when you press to clear the loop and stops the loop from playing through your amp. Silent Clear saves you from reaching over to turn down your amp or your looper while you clear it. The Express XT is an incredibly simple looper and easy to use. It works just like every other looper with record, stop, play, unlimited overdubs, and undo. We made it even easier with a dedicated LED per status. The Express XT can run on a 9V battery (included) and works right out of the box. You dont have to spend any more of your hard earned money to get a power supply just to use it when you get home. Not only is the Express XT the best, most full-featured compact looper in the world, its also the most affordable.
