Hello there! I got a quick question. I have a EHX smallstone Phaser, a Big Muff and a H&K Warp-Factor. When i put the Big Muff before the H&K each distortion pedal works on their own, and i can combine them. But when i hook the BigMuff after the H&K, the bigmuff seems to be de-activated. I no matter if it is switched on, it doesn't do any change to the sound, i wonder why this is like that.
