SnarkSN10 Stage and Studio Chromatic Pedal Tuner

Does this come with an AC adapter? If not, then what kind/model will I need to get and where can I get it?

Hi, does anyone have the actual physical dimensions of this pedal? length x width x height. i'm trying to find out if i have enough room on my pedal b

Is it chromatic? i like to de-tune my guitar a half step and want it to give me eb, ab, db, etc.

I see there are two 9V power adapter inputs in the picture, can this power other pedals with a chain cable?
