Sweetwater tone tweakers were also quick to zoom in on this pedal’s unique decay, tone, and mix slider controls. Compared to standard knobs, these sliders make small, precise adjustments on the fly quick and easy. Speaking of controls, the decay and mix sliders control the reverb length and intensity, while the tone slider offers invaluable adjustments of high-frequency character. Push it hard right for a brighter reverb with instant presence and body, or push it to the left for sonic washes that enrich ambience with a lingering, slow-burn presence. Whether it’s your first Walrus pedal or your fifth, the Fundamental Series Reverb makes an outstanding contribution to the sound of any pedalboard!
