My search box is broken today too. ( android phone )
Mind the phase. Some pedals invert, putting the effected signal and the dry at odds, that's what the switch is for. Sadly, it's a tiddler of a switch and you want to put more than one pedal in the blend loop.
Unless none are the inverting type you're kinda screwed. You could have all inverting, and always use the same number on, but as soon as you mix'n'match you'll run into mushy sounds and have to flick that tiddly switch.
Look up my recent posts on crossover blend when the search comes back online.
