Description

Introducing the Fulltone Mas Malo, your solution to the perfect fuzz effect. This compact pedal is ready to unleash a torrent of tone, from the subtlest of amp breakup to the most explosive atomic fuzz. With a unique 4-control layout comprising of Volume, Distortion, Color, and Heat, the Mas Malo allows you to sculpt your sonic signature with precision and personality.

For those seeking to replicate the gritty tones of rock greats or create their own unique sound, the Mas Malo's controls are highly responsive and wide-ranging. The "D" control stands for distortion and can be tweaked from a mild crunch to a roaring riot. The "H" (Heat!) control adds fiery intensity to your tone, while the "C" (Color) control allows you to brighten or darken your signal to fit any mix.

Under its fiery exterior, the Fulltone Mas Malo features three BC184C discrete transistors that offer a broad palette of controlled chaos. This pedal also includes top-mounted jacks with high-impedance input and low-impedance output, ensuring smooth operation with virtually any setup. Despite its small footprint, the Mas Malo is a true heavyweight in the distortion and fuzz arena, fitting comfortably on pedalboards of all sizes.

Key Features:

  • Distortion control ("D") for a wide range of tones
  • Heat control ("H") for intensifying your sound
  • Color control ("C") for tone-shaping capabilities
  • Uses 3 high-quality BC184C discrete transistors

Amazing sounds, but...

... as most muffs, it is noisy as hell. It sounds amazing at low gain settings, you get sweet fat blues overdriven tones, but once you rise the gain, oh well... The tones are great, but the noise is too compressed and you get hell. It is not a specific problem of this pedal, but muff circuits cause that and depending of your use you should be warned. Running on batteries help, of course, since you avoid dirty power, but the noise is still there. I play mostly strats, that are noisy per se, so gain never above 2 o'clock.

One of the few really “sound different” pedals out there

It’s a hidden gem. It is worth every penny, any fuzz and distortion lover should have one
