Maul distortion algorithms

Each drive stage in Maul features 32 different algorithms with which to process the incoming signal, selected with the Drive Type drop-down menu described in the previous section.

About the graphs

The graphs in this section represent the waveshaping response of most of Maul's algorithms. These do not make sense in the context of which some algorithms work, such as the Ring Mod and Digital algorithms.

The x-axis of each graph represents time, while the y-axis represents amplitude. With no processing applied (with the Drive Type set to 'Thru'), the waveshaping response can be represented by the graph to the right.
