Send in your Ernie Ball Volume pedal for the Premium Sealed Pot upgrade. 
 
The Premium Sealed Pot is a 25K pot that has a very smooth taper and is a big upgrade in durabilty and sound quality over the standard volume pot for Ernie Ball Volume Pedals. 
 
This Pot is compatible with the VPJR, MVP, and Standard Volume Pedals
 
The 25K Premium Pot requires an active signal such as after a buffer for the sound to not be degraded, we offer a buffer that we can install for an additional $30
 
The diameter of the pot is larger so the bracket that holds the pot needs to be drilled out. 
There is no instructions to install the pot yourself and this upgrade requires you to send in your Volume Pedal so we can install it. 
 
Once you place your order we will send you the shipping address where to ship your pedal to us.
