Hi 
I refer to this video of KT Tunstall. YouTube - KT Tunstall - Black Horse And The Cherry Tree
The thing she uses records what she sings or does on the guitar, and it loops. I really like the way she layers her music, and i was wondering if such a device is available here, and at what price
is it a pedal? can it be used as a standalone (sorry i am not familiar with electric pedals... whenever i see one, its always connected to another pedal or something and finally to the amp)
