What pedal(s) can you never quite kick off your board?

What pedal(s) keep coming back on your board despite your attempts to replace them or frustrations with them?

For example, I don't love any single sound on the oceans 11 but it's sheer flexibility (and my reluctance to buy a big fancy reverb pedal) means that it always occupied the pre-dirt reverb space on my board.

In a similar vein, the dd7 I have had for the last 15 years has never left any board I have gigged with. I don't love any of the delays but there is always a song which requires something it does whether that is a clean digital or analogue delay, the slightly shit chorus sounds from running it 100% wet on the mod setting, the reverse delay, the stuttering 50 ms delay sound, or the looper.

My gut feeling is that most boards should feature multiple of these workhorse pedals when people are gigging or playing with friends as they unlock such a broad variety of sounds despite doing none of them particularly well.
