So, after 2 years of playing without effects, I dug my old stompboxes out and have rediscovered that I still love 'em. So, I went whole hog and bought a pedal board (a powered SKB one) and have started configuring it. Only problem is...I don't remember the the "theory" behind setting up an effects chain. I vaguely remember that some effects are time-based (envelope filters?), and some are pitch based (wah?), and this affects where they should sit in the signal chain, but I don't remember the particulars. So...I need some explaining. The pedals I currently have (in order in the chain) are: Dunlop 105q wah--> Blue Tube 903 (overdrive)--> EHX Qtron+--> EHX Electric Mistress flanger--> EHX Small Stone phaser--> ...and I'm going to be adding an octave pedal into there shortly (as soon as I decide on one). I've read elsewhere on this board that a wah should come first, then the overdrive, than the flanger/phaser effects. I'm not sure about the Qtron, though. I tried putting the Qtron before the overdrive and got some pretty nasty noise and squelching (not the good kind of squelching). I've heard from some that the envelope filter should go after the wah-->od, but I've also heard that the envelop should be first in the chain so as not to affect it's response to to the input signal. I'm mighty confused at this point. Also...where would the octave pedal fit in this chain? I'm leaning toward putting it first in the chain so that the generated octave gets processed as a square-wave synth tone by the rest of the effects in the chain, but I'm not sure. Teach, pontificate, hypothesize...learn me somethin'!
