Hey out there. I haven't tried this but I was listening to a podcast by Brian Wampler on pedals (duh!) and he and another employee on the cast used 10 gauge rubber o-rings you find at hardware stores to place under your knobs. The effect is making the knobs harder to move by accident but still turn-able. I haven't tried it or even seen if it will fit but it seems worth a try. I have gotten rid of pedals that had super loose pots with crazy gain levels.
