Behringer PH9 - a cheap Phase 90 made for modding

[modelmonster]

thanks for the reply.
yes, we are talking about the same pedal .
the behringer ph9 phaser in the blue metal box

It is a strange thing ,
i dont know whats going on with this pedal but when i go out of my op amp big muff into the ph9 it has  a boost in volume and boost in treble but it makes my op amp  big muff sound great ,almost synth sounding but still with the big muff fuzz.

it does not behave like a phaser.

anyway i just thought i would ask if anyone knew how i could add a volume and treble cut knob  or tone knob it would make this pedal very useful to me.

as for the led i just put a piece of tape over it

thanks again
