MZ-2

This pioneering BOSS pedal blended an analog distortion circuit with digital processing to produce massive tones for metal and other heavy styles. A multi-mode selector provides three doubling options and two specially tuned chorus modes, unlocking a range of sounds that infuse the high-gain saturation with rich spatial depth.

Page	Parameter	Setting range	Explanation
1	LEVEL	0–100	Adjusts the volume when the effect is used.
	TONE	0–100	Adjusts the tonal character of the effect sound. Turning the knob clockwise emphasizes the high-band audio, and turning the knob counterclockwise cuts the high-band audio.
	DRIVE	0–100	Adjusts the distortion depth. Turning the knob clockwise gives a deeper distortion effect with longer sustain.
2	MODE	SGL, DOUB I, DOUB II, DOUB III, CHO I, CHO II	Switches between the six modes. The effects for each mode are as shown below. SGL: single mode This mode offers distortion sound only. DOUB I-III: doubling mode Adds a short digital delay (doubling effect) to the distortion for a thick sound. The delay times get progressively longer with the I, II and III settings. CHO I-II: chorus mode Adds a digital chorus effect to the distortion for a thicker sound. Chorus type II offers a deeper chorus effect than type I.
	OUTPUT	TYPE1, TYPE2	Specifies how the effect is output when the outputs are connected in stereo. TYPE1: When the MODE is set to DOUB I-III or CHO I-II, the distortion + delay (chorus) is mixed with the distortion to be output. TYPE2: When the MODE is set to DOUB I-III or CHO I-II, only distortion is output to the left channel, and distortion + delay (chorus) is output to the right channel. This offers a spacious sound.
