I'm adding a Blues Driver, Fuzzface Mini and Metal Zone to my signal chain. Does it matter what order they go in, since they're all gain pedals? I would like for the Fuzzface Mini to be at the end of it, because I'm getting an expression pedal that I want to use for both the Fuzzface and the Space Echo-RE202, which is a delay/reverb pedal. At the moment, I just have a Dunlop wah pedal and Ernie Ball overdrive.
