If you're expecting an overdose of funk from this fresh green fellow, you may want to look into the newer DOD FX25b or the Electro-Harmonix Q-Tron. The 440 is less pronounced than most of the filters out there and that subtlety is what makes it so sought after. Despite the relative shyness of the wah sound, it's ultra-thick and fills up a lot of sonic space. Since it's a touch sensitive effect, a great deal of the overall success of the effect depends on you. A simple two knob operation dials in the effect and a single switch activates the effect. This is back when DOD made their pedal tough as nails with heavy-duty switches that instilled the utmost in confidence. The popularity of this unit is on the rise due to the massive success of Radiohead and the band's use of the DOD 440. Re-issue time anyone?
