Building on EHX's looper legacy, the 45000 combines the familiar controls of a multi track digital recorder with state of the art features making it possible to create complex multi track loops quickly and easily. Each loop has four mono tracks and one stereo mix down track. The 45000 records non compressed, 44.1 kHz / 16 bit CD quality audio direct to a removable SDHC card (4 to 32GB). Each card holds up to 100 individual loops accessed with the optional 45000 Foot Controller (sold separately). Loop speed is adjustable over a two octave range, and reverse recording and playback are also possible. For extra convenience, a built in metronome to a separate Monitor Out and a Headphone Out are also included.
