I'll start. EHX Cock Fight. I have pedals that I've paid 10x more for on the same board, and I can always find ways to incorporate the Cock Fight and get some wicked sounds from. The fuzz in it is surprisingly good (I completely assumed it to be something I wouldn't engage) and the ability to fine tune the EQ/Tone using the knobs OR use it as a classic wah using an expression pedal, make it super versatile. It's cheap as dirt, makes a ton of great quality sounds, and does more than pedals twice it's price in the same category.
