Overall Impression

The sweepable Plate/Hall/LoFi/Sonar control rewards experimentation but confuses first-time buyers. Multiple owners note the mode knob isn't a 4-position switch as expected but sweeps continuously between algorithms, so blending Plate and Hall or LoFi and Sonar unlocks extra flexibility. Some found this unclear from Walrus's own marketing and had to relearn the pedal via demo videos, but once understood it opens up 'a myriad of useful tones' spanning jazz, ambient, and heavy blues.

The sustain footswitch and natural bypass decay set it apart from other reverb pedals. Owners highlight that stepping on the momentary sustain switch keeps reverberating everything played rather than just sampling the last note, letting players build a big wall of sound. Several also praise that switching to bypass lets the reverb decay naturally instead of cutting off abruptly, a detail called out as something 'every reverb pedal should do.'

An undocumented delay mode and always-on modulation are the pedal's most talked-about quirks. Commenters repeatedly describe a hidden trick: holding the sustain switch while turning the Program knob toward H (or S) turns the reverb into a delay effect, which surprised some users mid-performance. Conversely, several owners are frustrated that Plate and Hall modes can't fully disable modulation, adding an unwanted subtle chorus to clean solo or overdrive tones.
