The Mas Malo is a tiny pedal (2.5” x 4.4”) that you can easily add to your pedalboard. Fulltone have made sure that the input and output jacks are mounted on the top of the pedal, so it can fit snug between pedals with no annoying positioning caused by protruding side-mounted cables.
The Mas Malo has a variable DC, meaning you can affect the sound of the pedal depending on how much you power it. You can increase the headroom of the pedal by running it at a higher voltage, so at 18V you will have a more open sound with less compression.
