Named for the number of total seconds available in its 20 memory banks, the Electro-Harmonix 1440 is a stereo phrase looper pedal designed for electric guitar and other instruments. It provides a digital signal path for your loops, recording and playing them back at uncompressed sample rates and resolutions of 24-bit / 44.1 kHz, allowing you to store your loops in 20 different, selectable memory banks. Also provided are capabilities for unlimited overdubs, undo/redo for deleting/restoring your last pass, half-speed and reverse effects, adjustable fadeouts, and an analog dry-through pass for your uneffected signal.

The pedal offers a level knob for controlling the loop's output volume, while LED indicators display record, play, FX, and memory modes. Your dry signal will always remain at unity gain, and while you’re adding overdubs, you’ll hear no loss of volume to previously recorded tracks in the loop unless you adjust the Overdub control, which dictates the level of the overdub. 

A stereo signal path is provided, giving you two 1/4' input jacks and two 1/4' output jacks. Should you wish to control certain parameters of the 720 Stereo Looper from a compatible, external footswitch, you can do so through the 1/4' TRS foot-control input jack. MIDI sync'ing your loops is also possible over the 5-Pin DIN jack. 

All your recorded loops remain in their memory banks until you manually erase them, and you can upload your favorite loops to a compatible app over the mini-USB jack. The app is free and available separately. The pedal includes an AC Adapter.
