Walrus Audio Slo Multi Texture Reverb - UsedThe Sl Multi Texture Reverb is Walrus Audio's perfect pedal if you're looking to make big, huge, ambient soundscapes. With knobs for decay, filter, mix, and depth you can really dial in your reverb. The algorithm toggle switches between three different reverbs and the X knob controls the effects on those reverbs. This Sl has very minor wear on the bottom.
