Walrus Audio Slötva Obsidian

(0 customer reviews)

Walrus Audio Slötva Obsidian Reverb allows players to create lush, modulated, sleepy and ambient soundscapes. The toggle switch allows three different reverb modes, Dark (Lower Octave), Rise (Ambient Swell) and Dream (Latching Pad), while secondary functions on the switch change between different wave shapes for the modulation on the reverb trail. This is a special, limited edition.

DARK – Add a lower octave to your reverb trail. Here you’ll create deep and wide atmospheric sounds and channel nightmarish soundscapes. X knob sets the level of a -1 octave signal that feeds the reverb.

RISE – This is an auto-swell reverb for beautiful cinematic swells. Don’t rush it. Let it breathe and gently wake up. X knob sets the amount of time it takes the reverb to swell in after a note is played. Set lower for shorter rise times and higher for longer rise times.

DREAM – Here is a lush reverb with a latching pad function. Press the sustain switch to latch signal. Experiment with the X knob to add vibrato over the pad. Press sustain again and pad will decrescendo according to where decay knob is set. X knob sets the depth of vibrato applied to the reverb trail.

The Slötva also features 3 different wave shapes accessible by holding down bypass while switching the algorithm toggle.
SINE – Smooth and even pitch up and down modulation.
WARP – Asymmetric pitch up modulation similar to a warped record.
SINK – Asymmetric pitch down modulation for sinking detune similar to a Bigsby.

The pedal has a number of cool features, including Reverb Texture (when pressing and holding the Bypass Switch). The sustain switch ramps up the reverb trail to maximum, creating long dreamy reverb trail when pressed and held.The Slötva can run in trails or no trails mode.
