What is a Wahfull® and why would I want one?
11 years ago I made a couple of fixed wah wah effects I called the Wahfull®... they were simply the guts from a wah wah stuffed inside a box with a knob so you could find that perfect Mid-Boost sound every time you kicked it on. Nice effect, sold a few, moved on.
Last year Robin Trower called me and said he was doing some gigs with Jack Bruce and asked "Would it be possible to have a wah wah in a regular box so that one could get that "fixed wah" sound by clicking on the pedal?" So I made one up and he's been using it ever since.
Want a Wahfull? Let me know! I may go in to production with this, depending on demand.
