“Walrus audio slo, I love the art but it's just another shitty Fv-1 reverb with uninteresting algorithms.”— tails_the_gay_fox on Reddit
“The reason why I'm writing a review on NPD is because it has a glaring flaw. *Hiss.* Or white noise, whatever you want to call it. **It is really really bad.** It is so so much louder than the noise contributed by my other pedals.”— [deleted] on Reddit
“in real life it was super sterile and just underwhelming. Some people have said it takes a lot of time and effort to get sounding natural and full of life but I couldn’t get rid of it fast enough. Same can be said for the Walrus Audio Slo”— gagegomes on Reddit
“I'm not feeling this one.”— @alexbreyer6921 on YouTube
“Walrus is not compelling and versatile to me ears.”— @theleastimportandthingtoknow on YouTube
“I'll happily stick with that one.”— @agerven on YouTube
“Why. Doesn't. It. Have. MIDI.”— @jamesnichols5998 on YouTube
“One thing to be aware of with the SLO - it’s got a noticeably high noise floor, even when disengaged. I’ve had this confirmed by Walrus.”— chilli-potts on Reddit
“I had it and sold it. Seems like a good match for ambient / shoegaze, but was a bit too digital verby for me.”— Baskervils on The Gear Page
“Lovely effect but they lost me at 2:42 as I heard the pedal cutting lows as it was kicked on.”— @Topsy_Krett on YouTube
“I wanted to like the SLO, but just found it muddy and a bit of a one truck pony.”— shoule79 on Reddit
“I wonder why they don't do these in stereo, seems a bit limiting...”— @jelnet on YouTube
Not complaints — practical notes from owners that didn't affect the score.
“Just spent some time with a Walrus Audio Slo. Reverb with a lot of modulation variation. Warps, reverse and other sounds that connect to Shoegaze playing.”— nibw43 on Reddit
“I had the Walrus Audio Slo which was beautiful but not stereo and, for what I need, less versatile than the HoF2.”— Special-Pigeon on Reddit
“Had to use the manual and watch a video to figure out how to use the Walrus Audio Slo pedal, and I still refer to it sometimes years later.”— So_Famous on Reddit
