I got this Digitech grunge pedal and a Stranger amp. 20 cube. So, do I need to match the settings on my pedal with that on the amp? Like if bass is 3 o clock on pedal so 3 o clock on amp as well? 'Cuz thats what I have been doing. And the sound of the 1st, 2nd and 3rd string seems cracked. More so if I play 2 of em toghether. So all chords except power chords seem horrible. I will put in a demo ASAP. Any remedy? Except new amp?
