When DigiTech developed the PDS 8000 looper pedal over twenty years ago, it looped eight seconds of audio. When they reinvented loopers in 2005 with the original JamMan(R), over 6 hours worth of material could be stored on a removable media card. Now, DigiTech(R) 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 expansion slot giving you the ability to store over 16 hours* of material in an additional 99 slots.
