Hello, so i am off to my first pedal after 1 year playing my american prof strat in mostly clean mode on a blues junior iv. I have found a line 6 dm 4 pedal with a number of great pedal models in it and now have it in hand...all set up and working fine. But my experience with any pedals is just a zero. Some questions: 1. What settings do I set the amp to when the pedal is connected. Do I set the distortion level from the pedal and then arrange the tone from the amp or do I put the knobs of the amp to a particular setting and then set the tone from the pedal. The pedal has knobs for drive, bass, mid, treble, volume and gate. 2. Upon pressing the footswitch of the pedal I note a strong hiss from the amp. Can I remove this? 3. I can lower the gain close to zero for this hiss to be removed but then I barely get any volume from the amplifier. Finally anyone using this pedal can provide any other information about it and how you find it in general.
