Sorry to hear you are having problems. I checked our support records for open tickets and didn't see this issue in our system, so I'm not sure what happened. My apologies for any delay. You may contact me directly at
james@missionengineering.com and I will try to take care of it. You can also call customer service if you need to talk to someone. Our 866 number and hours on on the website. My personal extension is 511.
A couple of quick notes: If a Mission pedal was purchased new direct from Mission or an authorized dealer, it is covered by a one year warranty. There should never be any question about replacing any parts under the warranty terms. Different dealers have their own return policies, but Mission will always repair or replace parts under warranty if necessary. If your pedal is under warranty you can request an RMA and return it to us for repair, or we can send you a self install replacement. For reference, terms are on the support page at:

For pedals that are used, bought on auction sites, from friends etc, or have an expired warranty, we offer a repair service where customers can return pedals to us and we will repair them, or upgrade them for a small charge. We also sell several maintenance kits on the web store. The potentiometer is a specialized part we have made for us. It makes up the majority of the cost of the kit. If you purchase the kit, we are pretty much throwing in the switch and the jacks for free. If we sold the pot by itself, it wouldn't really be any cheaper. The kit is $39 which seems comparable to the 20 - 40 or so for replacement volume and wah pedal pots I could find for sale on the web.
Hope this helps. Please email or call me and I will see if we can resolve this for you.
