trying to level out all my presets. For some reason I am getting different volumes from the same pedal when I switch from preset 4 and 5. I have OD1 one selected and saved in preset 4, then I do the same for preset 5. When I switch between the two presets, preset 5 is significantly lower in volume. ( no other pedals being used) What’s up. I changed the buffers but didn’t notice any change.
