I have the same problem with my DOD stereo chorus. I need to adjust the screws on the switch so it wont stick. Dod is really wierd anyways, I love the tones that I get out them but you have to change the jacks and possibly the switch when you get them. Plus, you will probably have some cold solder joints as well. That’s a lot of crap to go through just to have the tones that I want….they should just work harder at making better pedals.
