Digitech JamMan Stereo LooperWe've Reinvented Loopers Again. When we developed the PDS 8000 looper pedal over twenty years ago, it looped eight seconds of audio. When we reinvented loopers in 2005 with the original JamMan, over 6 hours worth of material could be stored on a removable media card. Now, DigiTech has raised the bar with the new JamMan Stereo Looper with the ability to store 35 minutes of CD quality loops in 99 internal memories as well as having an SD memory card
