MAS Effects Unveils the Sona Fuzz Pedal

An extreme, high gain fuzz pedal with a touch of class

MAS Effects has just revealed their latest pedal with the Song Fuzz. This Tone Queen gives you incredible tonal control with a switch to adjust the input filter, and a knob to pan between high and low pass filters on the output.

The fuzz circuit this pedal is based on is one that’s been floating and evolving in the DIY community for a very long time. Its exact evolution isn’t precisely clear, but the primary contributors are Doug Hammond, Gus Smalley, and Aron Nelson. 


Sets the amount of gain, distortion, fuzz, sustain, or whatever you want to call it. Like with most fuzz pedals, it will interact with the volume knob of your guitar. e.g. roll back the guitar volume at low FUZZ levels to clean up the signal considerably.


Controls the overall output of the pedal.


Pans between cutting highs or lows.

Body Switch

Fattens or thins out the signal going into the pedal.

Soft-touch Foot Switch

Tap to switch between true bypass and engaged; Hold to temporarily bypass when engaged, or temporarily engage while bypassed. 

Hold while connecting power to toggle whether the pedal will be engaged or bypassed whenever it’s powered on.

Internal Controls

FUZZ Ceiling

Need MORE gain? This pedal has insane amounts of gain on tap, but a lot of people expect to be able to turn the knobs any which way (and all the way up) and have it sound great. This isn’t unreasonable, but it’s limiting. If you max out the gain, the pedal gets really noisy! So inside, on the lower right, is a blue and white trimmer that tames it.


Can be adjusted to give a gated, sputtery sound.
