I have a wah pedal, a chorus pedal, and a digitech rp80 multieffects (that I use mostly for the tuner). What would be the best order to wire these in?
^ Wrong. I'd go wah->multieffects->chorus->amp. You should experiment a bit, though, there's only 6 permutations of those effects (?).
I'd take only multi, or only other pedals. In my own experience digital and analog pedals don't work good in combination.
