Since 2009 the Excalibur (Excepted Ultra) potentiometers are 1 meg Log. Prior to 2009, we used 500k Log.
The Expert is currently and has always used 250k Log pots

For instruments prior 2016:
First of all, you should make sure you use good cables such as RapcoHorizon, with a branded plug (Neutrik, Switchcraft).
If you stepped on the guitar cable, the jack input may have been damaged and needs to be replaced. The original reference is Switchcraft  152B but due to manufacturing inconsistency of Switchcraft for this item, we recommend to use an equivalent. Any ‘long barrel stereo’ jack should work just fine.

For instruments after 2015 that are equipped with the current locking jack unit, reference is Neutrik NJ3FP6C-B

Tools for changing the 152B long jack:
Do it yourself (based on a 14mm ring spanner):
