i have a gig tuesday. im busy saturday due to marchign band all freaking day (no life). sunday stores closed, monday school then marching band practice (no life). basically i need a new distortion pedal cuz my boss ds-2 was freaking stolen. i narrowed it down to the big muff and the ibanez ts9

so should which one do you advise i should get. or should i get both and return which one i dont like or just keep them both.

and which one would be best for a volume boost
