MAS Effects Introduces the Sona Fuzz Pedal

MAS Effects has introduced the Sona Fuzz pedal. It is described as an extreme, high gain fuzz pedal with a touch of class. This Tone Queen gives you incredible control with a switch to adjust the input filter, and a knob to pan between high and low pass filters.


Fuzz: 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.

Volume: Controls the overall output of the pedal.

Tone: 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 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.

Bias: Can be adjusted to give a gated, sputtery sound.

Technical Specifications:

Jack placement: Top-mounted

Power supply: 9V DC, 2.1mm center negative (not included). No internal battery clip

Power consumption: 19mA

Bypass: Relay switched true bypass
