Also, a pedal without an input cap can cause DC current to run through your pickups, which can cause volume loss and change the frequency response (it attenuates treble, usually).
Lack of (or malfunctioning) input or output caps can also reverse-bias the blocking caps in other pedals in your chain, which can damage them if they are polar (electrolytics, tantalums). I've never seen it happen, but it's possible.
