Main features

Simple and reliable loop play
The new "loop quantize" function automatically adjusts the timing of the loop end.
This makes it easy for anyone to create looped phrases of an accurate length.
Up to 5 minutes 30 seconds of extended phrase recording
Up to ten different loop phrases and one one-shot phrase can be saved for a total of 5
minutes and 30 seconds of recording.
Control the phrase tempo in real time
The tempo of a phrase can be controlled in real time without affecting its pitch. A
phrase recorded into internal memory can be made to match the tempo of a live
performance, opening up new possibilities during a gig.
This feature is also useful when you wish to slow down the tempo of a guitar phrase to
learn and practice it.
Dedicated mic input for vocalists
Since the INST jack and MIC jack can be used simultaneously, you can create new
sound-on-sound performances that combine guitar, vocals, and percussion.
Easily record audio signals from a CD or MD
It's easy to record audio signals from a CD or MD connected to the AUX IN jack.
Since the vocal or guitar solo can be erased from the audio signal while it is being
recorded, it's also easy to create minus-one data.
Pedal design for hands-free operation
You can use the pedals to start/stop the performance, switch phrases, and set the
tempo without taking your hands off of your guitar.
