dod fx25b seems unresponsive

[ElectroStompbox]

it seems like if the sens. knob if only lower than max it doesnt make any change, also the range isnt that diff either, is that just the way the pedal is or, am i doing something wrong?

Either your level is too low or it's died on you. They Do wear out I've found.

1) What bass are you playing and what kind of output does it have?

2) How hard are you playing?

olp music man, passive into crate bt100 combo, when the sens is below three quarters it only opens up when i slap, 12 o clock and lower nothing
