The Bass Valkyrie vintage chorus pedal is our bass centric take on those 80's flangers we all had but sadly sold at some point. Using similar delay line technology from that era, the Valkyrie pedal also has a wider range of control and depth to be able to do more than just that chorus sound. A classic effect derived from taking a signal through a delay line whose speed is being modulated by a low frequency oscillator and then adding that signal to the original. Simple to drive with just two controls, Rate and Depth. Rate controls the speed of the triangle low frequency oscillator from a slow swoosh to a rapid fast Leslie and beyond. Depth controls how much deviation in delay time of the delay line is allowed. At zero, the signal is fattened but without any pitch change, as depth is increased the pitch deviation becomes more.
