hi,

i have just bought new tube zipper pedal.
there is some problem, because i can hear some released component inside (if i move with it, like released screw…). i tried it and it seems to work, except one thing i am not sure about.

it is possible i dont fully understand concept of the pedal, and if the filter included is LPF.
but it seems like i am not able to fully filter the singal which is going inside.

for example
lets say i put resonance wherever and frequency, sensitivity to 0.
signal goes still trough and the amount of the resonance will influence somehow the loudness of the signal.
i can still hear the peak of the resonance and its frequency if i move the knob, but there is this “original signal” added to it.

maybe i should add i test it with no guitar sound (i am not guitarist, and have no experience with pedals, i want to use it in my studio, as an effect for dirtyfication, crazynifaction …

please can you answer.
is it feature of the pedal?

thanks for reply

tomas
