I am a guitar player and I recently got a Zoom g3xn multi fx pedal as well as an Orange Micro Dark amp. I have been using the pedal’s amp and effects models connected to the Fx return of the amp and it has worked perfectly. However, when I connect it to the front of the amp it produces volume but the distortion control on the amp does not work; no matter where the gain knob is, the sound is clean. This is true even if no effects are activated on the pedal. My signal chain is simply guitar into pedal into amp. The problem only exists when the master volume on the pedal is low but that is the volume at which I use it as otherwise it is too loud. What could be causing this problem? Any help is greatly appreciated!
Edit: My speaker cab is a 1 12 and Celestion vintage 30 loaded. Everything works fine when just running straight into the amp: I can get nice distortion at low enough volume. The problem is basically getting the same volume and tone going through the pedal into the amp as going straight into the amp.
