Egnater Tourmaster 4100 treble trouble

Hi,
I have a egnater Tourmaster 4100 Head with a problem. On the fourth channel the treble knob works like a Backwards volume knob, if you turn up the treble the amp gets quiet, if you turn it down amp gets louder. never heard of this problem. also there is no treble in that channel what so ever. this only happens with the fourth channel all the other ones sound perfect.
ANY HELP WOULD BE APPRECIATED

i have a sneaking suspicion that i would have to replace the potentiometer, but i dont know what potentiometer to use so help with that would be fantastic too if that is the problem.
Thanks in advanced
 
Not knowing how it's wired in the circuit.
My though is that a cap is shorted out and as you turn the dial it bleeds your signal to ground.
Hence the volume decrease
 
But would that cause it to have no treble at all in that channel too? Cause that's the issue mainly that the treble is not that and acts as a backwards volume knob.
