MOOER PITCH BOX pitch shifter. Operation confirmed. Manual included. I think it's functionally excellent quality to be able to use 3 modes: harmony, pitch shift, and detune in this size. Using it as a normal pitch shifter is good, but the Detune Chorus in Detune mode is also excellent (around the 3rd setting). For some reason, I only had an English manual, so I printed out a Japanese manual and will include both. There are a few minor scratches and paint剥がれ (hazing/peeling) from use, but there are no functional problems. Velcro is attached to the back. Please check the photos for details. Since this is a used item, please refrain from purchasing if you are sensitive to such things. Please read the profile to prevent any trouble. Thank you.
