Description

The DVF (Dual Voice Filter) based on a circuit by Craig Anderton from the 70s will give you tonal options like no other.

We then added on-board overdrive. Used for guitar as a tonal shifter, cocked wah, solo enhancer and more but also consider other instruments like Harmonica, Voice etc.

The circuit comprises four stages:
· Input gain stage
· Low to mid frequency sweep filter
· Mid to high frequency sweep filter
· Mixing stage
