Inspired by the vintage Bell and Howell 385 Filmosound projector that guitarists have modified and used as guitar amps, Walrus has created a dynamic and responsive overdrive modeled after the projector's tone. The 385 was developed to have the same simple but effective tone control as it's older relative, but unlike the projector, the 385 breaks up the single tone control and integrates separate, boost and cut bass and treble, allowing the player to get more creative with mid-frequency scoops and bumps allowing for a much wider array of tones to be achieved. The pedal is internally running at 18v, which helps us nail the same dynamic feel of the amp in a stomp box. This means it is extremely sensitive to how hard you dig in – just like the amp.
