Congratulations on the purchase of your new 

M-120 MXR Auto Q

stomp box! MXR effects have been favored by professional
guitarists for decades. While other effects have come and gone,
MXR’s keep getting the job done … with bulletproof construction,
quiet, reliable switching and tasteful, musically inspired tone
shaping.

DESCRIPTION

•  Effect triggers equally at 

all

playing volumes, by adjusting sensitivity 

automatically.

• More adjustable tone parameters than any other auto-wah!
• Bonus “shimmer” effect, adjustable for Rate, Blend & Decay.

POWER

MXR M-120 Auto Q uses one 9-volt battery. The battery access is through
the bottom of the pedal. The Auto Q uses the Dunlop ECB03 Adapter
(ECB03E for Europe), a 9-volt DC regulated AC adapter. Plug polarity is 
positive on the barrel and negative in the center. 

Note:

Battery must be

installed to operate the Auto Q unless an AC adapter is used.
