Classic Boss MT-2 Metal Zone distortion pedal. Made in Taiwan. 

Gently used in a home environment. 

Sold ‘as is’. 

Tested as working.

Comes with the original box and instructions (see photos).

You will need to buy or use your existing power supply. [As per the instruction manual, you can use a dry battery 9 Volt (9V) type, or AC Adaptor - with the Boss PSA-120, 220 or 240 option. I recommend using 9V battery].
