Where is the best place to put an external drive or fuzz pedal i) Before the Amplifire input ii) In the Amplifire FX loop, with the loop in position 2 (i.e. with pre-fx, before the amp block) I have all of mine before the input and this seems to work well. It also leaves to FX loop free so I use this for a reverb and looper pedal. Has anyone experimented with the different options above? Would be interested to hear your thoughts.
