The Freq Up combines a tubescreamer style overdrive circuit with frequency adjustable clean boost.
The overdrive circuit comes from voicing two of the Cerberus pedal. This is internally combined with the clean boost circuit, allowing you to push the right frequency voicing for your rig to cut through the mix.
In combination with the comprehensive internal controls, this means the Freq Up can take you from a sharp, saturated, aggressive high-mid voicing to a soft vintage style overdrive, and completely over the edge if you feel like it.
