ok so im finally gonna get this pedal
and have a few questions

ok i was trying out this pedal and i liked it alot but one thing. I noticed was that i couldnt do pinch harmonics with out great effort and id like to know why the pedal is like that, if anyone knows
and i was wondering about feedback with this pedal too since the god damn music store wont let me crank it. I am currently using a boss ds 1 i was wondering if the metal master would give more or less feedback then that pedal(ds 1)?
