Fulltone Mas Malo




1 item left

Fulltone Mas Malo gives you a big fuzz sound at any volume level. Works with single coil and humbucker pickups alike. When you turn the distortion down, you will get Jimmy Page- and David Gilmour-style drive sounds.


V (Volume): Sets output volume level
D (Distortion): Sets the amount of distortion/fuzz. Starts from quite mild overdrive, goes all the way to heavy fuzz
C (Color): Tone control for the pedal with a lot of range. Starts at 7 o'clock with soft, full tones and ends up at 5 o'clock in gnarly garage fuzz tones.
H (Heat): Sets the bias for the first transistor (Mas Malo has 3 NOS BC184C transistors in it), affecting the distorting and character of the pedal strongly.
  • Power requirements: 2.1mm 9-18 V DC centre negative power supply or 9 V battery. 8 mA.
  • Made in USA

Guitar Player Magazine review:

"I love pedals with backstories—call it the curse of being a journalist. Although the flame-red finish and pepper graphic are relevant clues, the Mas Malo (“More Bad”) is actually named after one of Fulltone founder—and spicy food fanatic—Michael Fuller’s favorite Mexican restaurants.

Not surprisingly, the pedal is one scorching machine that delivers white-hot fuzz tones. However, Fuller also took pity on more tender “gastronomical types” by designing the Mas Malo to offer less-piquant overdrive sounds. For example, I turned down the Heat control (which re-biases the first transistor in the circuit) to about 8 o’clock, and the Drive knob to 11 o’clock, to craft a guitar sound very close to that of Badfinger’s 1970 rocker “No Matter What.” No need for Rolaids there.

Then, I got brave and dimed the Drive and Heat controls for an onslaught of harmonically rich saturation that shrieked like demons burning in hell fire. Call a doctor! If that level of mayhem is overkill, take heart that you can dowse the inferno somewhat by softening your picking attack or turning down your guitar’s Volume. The Mas Malo is a badass, but it also has a soft side."
