DVF - Dual Voice Filter - Cocked Wah w/ Overdrive - WoW

$8.95

The DVF (Dual Voice Filter) is based on a circuit by Craig Anderton in the 70s.

We then added on-board distortion. Completely moddable to taste.

Used for guitar per the Video Demo, consider Harmonica for a moment?

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

I highly recommend a larger enclosure than shown in the video (125B) if you are not experienced with enclosure layout etc.. it is a tight squeeze. Additionally you may want more room for knob control etc... a 1590BB would be an excellent size!
