hi there, these are the pedals in my line-up right now. amp--> DOD 410 phasor-->Ibanez CS-9 (chorus)-->DOD 250 Overdrive (on all the time for tone)-->Big Muff-->Boss Octave. The only thing I know for sure is that when I have the chorus and big muff on the the chorus has to be earlier in the chain because the sound it creates is great. If the order is reversed the sound is choked out. any info would be great. from a beginner pedal head.
