Key Features
The SubZero Critical Mass Distortion Pedal takes your gain up a level while adding immaculate articulation and a rich dynamic response. Don't be deceived by its simplistic layout, this pedal is incredibly versatile. You'll be able to achieve a wide range of tones from smooth saturation to high-gain grit.
With an interface consisting of three knobs and a toggle switch, dialling in the perfect tone couldn't be easier. Use the switch to flick between 'Soft', 'Normal', and 'Tense' to find the most suitable voicing and then use the controls to fine-tune your dream distortion tone.
The Critical Mass is a gain machine as well suited to articulate lead playing as it is high-gain chugging. As the pedal says, just "Apply Mass" to the footswitch and you're away.
Please Note: This pedal does not come with a power supply. One can be purchased here.

With the SubZero Critical Mass Distortion Pedal, the power's very much in your hands. A lot of distortion pedals have one tweakable sound, this is the opposite. Thanks to the responsive nature of the controls there will be nothing stopping you achieving a broad range of distorted tones:
The SubZero Critical Mass Distortion Pedal is designed to accentuate your dynamics, tighten your tone, and elevate your playing. Thanks to the inclusion of an all analog circuit, you’ll struggle to make this pedal sound harsh, even with extreme levels of gain. You’ll find that the subtle touches of compression are perfect for evening out your performance to make parts feel consistent without compromising the quality of your tone. The true bypass design keeps your dry signal pure and helps it pair well with other pedals, especially overdrives as this pushes the gain a little further and adds grit on top. Whether for chords, lead lines, or just chugging on the root, the Critical Mass will tighten your tone and add a real kick.
