Featuring a streamlined interface of one volume knob, pedalboard-friendly design and maverick JFET/germanium single circuit design, the Wren and Cuff Phat Phuk is a hybrid boost designed to veer more toward "dirty" than "clean." Intended to add a volume bump to your signal with the slight bite of a germanium overdrive, this effect is at home on a pedalboard in need of some extra oomph during a solo or breakdown.
