Bartolini, bass boosting problem-need help

Hi,
I am having a problem with one of my Bartolini preamp. This one is NTMB918 HR 4.6 which was with me for 10 years but I just noticed that I lost the boost on the bass pot but cutting still work. With treble boost and cut all work OK. From the center to boost hardly notice any change compare to my other bass with same NTMB.

Wonder if you can help me with the problem.
Thanks,
Chalie

I found out this morning thet the cable between the pot and the circuit is broken inside and now it is fixed so no more open help. Thanks TB.
