I just finished building it and it sounds awesome! I don't have a high gain amp so I can't really test it as it is entendent to be used. When I turn the gain knob I barely get any range difference. It goes to no gain then at around 1/8 it goes to full on distortion at the 1/2 point it pretty much max out the distortion , rendering the last half of the knob pretty useless xD the range changes a bit depending on where the eq knobs are set. And the range is most noticable with the toggle in middle position. Is this all normal on a vibrochamp amp ? Just wanna make sure I didn't do anything wrong on my build thanks !
