Series vs Parallel
This is where the pedal opens up.
Parallel - both stages run alongside each other
Clearer, more dynamic, lets you hear each stage separately. Ideal for blending clean and character
Series - one stage drives the other
More saturation and compression, thicker, more pushed sound. Feels closer to stacked drives and fuzzes.
Controls
