Cry Baby 535q. Good condition. I lost the battery compartment cover so I just used gorilla tape. That does not affect the function. I lowered the price though. Also, at the recommendation of a tech, I put a small felt pad (like used on furniture legs) under the pedal above the button. The tech was right -- that improves the function, making the click just a bit more solid. Obviously, that can be easily removed but I would say try it out first. Anyhow, I just tested it all out and it functions perfectly. Still my favorite effect pedal.
