Solution: Hank over at Effects bay now has some cool stickers available that adhere to your pedals so you can mark your settings. The part you mark your settings on is white so you can clearly see where each and every knob should set. No more smudging or accidentally wiping off settings! The sticker material is a sort of vinyl and not paper which makes the sticker more durable but also cleaner and easier to remove should you ever want t0 change the settings or sell the pedal.
There are a bunch of brand specific stickers such as “Ibanez 4 Knob”, “Boss 3 Knob”, “MXR Wide 2 Knob” among many others. For non specific brands there are “Single-Knob” stickers as well as “3 Way Toggle” stickers for switches. The Pedal Label system is available in a full pack of 6 sheets or a mini pack of 2 individual sheets. They are very reasonably priced as well. I love practical products like this!!!
