		signal. You can also use it as a limiter to
		suppress only the sound peaks and prevent
		distortion.
	LIMITER	The limiter attenuates loud input levels to
		prevent distortion.
	TOUCH WAH	You can produce a wah effect with the filter
		changing in response to the guitar (bass) level.

		two octaves lower, creating a richer sound.
	PITCH SHIFTER	This effect changes the pitch of the original
		sound (up or down) within a range of two
		octaves.
		Harmonist is an effect where the amount of
	HARMONIST	shifting is adjusted according to an analysis
		of the guitar input, allowing you to create
		harmony based on diatonic scales.
		This effect uses MDP (Multi-Dimensional
	OVERTONE	Processing) technology to add new harmonics
		to the sound, producing resonance and
		richness that was not present in the original
		sound.

Harmonist is an effect where the amount of shifting is adjusted according to an analysis of the guitar input, allowing you to create harmony based on diatonic scales.

*Because of the need to analyze the pitch, chords (two or more sounds played simultaneously) cannot be played. Be sure to mute all the other strings and play only one note at a time.

*When you are to play the next string while a certain sound is still playing, mute the previous sound and then play the next one with a clear attack. If the unit cannot detect the attack, it may not sound correctly.

*The sensitivity may vary according to the guitar’s TONE knob and pickup type.
