Volume Pedal Stopped Working Correctly

Hi,

I was using my expression pedal for volume since years without any issue. It stopped working correctly. I think I should have missing something but, I can't find what the problem is.

My expression pedal for volume is connected on Remote Pedal 3 port. Calibration is done. When I use the pedal it's like %5 affecting the volume. I am also using another exp. pedal on Remote Pedal 4 for wah and another one on Remote Pedal 5 for morph without any problems. I switched the exp. pedals etc. but nothing has changed. What am I missing?

I don't completely understand the scenario.

When calibration is done and has been successfull, the bar below "Calibrate" moves from minimum to maximum. Is that the case? Or is this were you see the bar only following to 5% of the range? If the bar doesn't cover the fiull range, there is something wrong with cable or pedal itself.

When the bar moves from minimum to maximum, hardware seems in tact. Then it's unclear what the 5% are really related to. Does it mean each Rig starts with 100% volume when pedal rests in toe position, but you can only lower down tp 95% if expression pedal is in heel position? In that case check Volume Padal Range in Rig Settings. Its default is -5. If you set for example to -1 it could have the effect that you describe. And if Volume Pedal is locked, this affects all Rigs.

Hi, thx for the response Burkhard.

Yes, "Calibrate" bar moves from minimum to maximum. Also on Rig Pedal Settings (Page 3/6) value bar moves from minimum to maximum. Despite everything seems fine, the affection on the volume can barely audible like %5. I also tested with other two pedals with different ports.

Any other recommendations folks?

check your cable. I had a broken cable and experienced some strange volume fluctuations

If the bar is moving from 0 to 100% then the pedal and cables,are working properly so the issue must be a setting in the KPA itself.

Where is the Volume located in the signal path? In front of a dirty amp or Od pedal will mean that volume barely changes over most of the pedals travel although the sound may clean up as the pedal is moved towards heel.

How is the pedal range set in the rig menu? Anything less then -5 will restrict the effect of the pedal movement.

Do you have any of the “>” options ticked in the setem menu (Wah > Volume etc). I wonder if having a volume pedal and Wah>Volume could create some conflicts between the two which cause strange behaviour?
