Walrus Audio ERAS Five-State Distortion. FEATURES: - Eras is a no apologies, high-gain distortion that’s ready to chug, shred, and palm mute with tight response and multiple distortion textures - Use the Blend knob at max for a full distortion onslaught or roll back the Blend knob to creatively stack and mix other dirt pedals placed in front of Eras - Great for bassists that want to blend in their dry signal as well - Features a five-position rotary knob. Think of each position as a different “flavor” of the pedal. Blend in dry signal or other pedals in combination with the gain states for a near-infinite amount of distortion sounds. - Power requirements are 9VDC, center negative (100mA minimum)
