Description
The slö multi texture reverb allows players to create lush, modulated, sleepy and ambient soundscapes. Stocked with three different algorithms specifically designed to invoke textures for bringing dreams from your subconscious to reality. 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. Combine deep modulation with long washy trails and experience, the slö.

I've had the Walrus Audio Slo pedal for about two weeks at this point and I've tweaked every setting to every position multiple times to get a feel for the full range of sounds that I can get out of this pedal. It's extremely versatile. The dream setting is exactly what it says, it's absolutely dreamy, every note is a lullaby of ambiance that is as saturated or as dry as you want it depending on where you have the "Mix" knob set to. The dark setting can sound absolutely haunting and ominous or it can even sound soothing. It just depends on how you set the knobs. *THE RISE SETTING* If I were to have any complaint it would be with the rise setting. If you are playing at low volume through an effects loop on a tube amp, the rise does not work. The signal isn't hot enough to push through the circuit. I didn't dock this pedal any stars for this because I understand that the nature of this effect is totally dependent on the signal strength by design. All you have to do is crank your amp and you will get the full epic effect of the rise setting which can be tweaked to creep up slowly behind your dry sound or you can cut the dry sound all the way out with the "Mix" knob and make sounds that sound like you are playing with a bow such as a violin or cello. If you just want some "normal" or "traditional" reverb flip the switch to dream or dark and turn the "X" knob all the way down, or almost all the way down, or wherever you want it because it's going to sound good regardless. I have had a blast over the last two weeks pushing sometimes bazaar sounds out of this pedal. It is my first but will not be my last Wallrus Audio pedal. If you're on the fence, just do it, if you get it and don't like it you can always return it. I hope this helps anyone who's thinking about this pedal.

We got the Reverb effect unit last week, my son went to his bass teacher for his class, they test new Slö Multi Texture Reverb and his second hands Sugi bass. His teacher are professional player, ans they are impress Warlus unit sound, function and building quality, compare to his teacher's many reverb effect units, he say Warlus unit is fantastic, the other reverb effect unit like toy. Warlus is hard to find in Asia, we had been to Japan and could not find it, so we decide to order from Amazon, it is very nice experience to purchase with you. Regards

This pedal does so much. It's obviously meant for ambient type music, but if you set it to any of the 3 modes and turn the decay down, it can function somewhat like a normal reverb pedal. The entire range of every knob is fun to mess around with. The sound quality of every effect is great, even with gain. I really like putting the reverb into an analog delay to give it more padding. My only complaint has to do with the gate present in the rise function. It may just be the fact that my amp doesn't have as strong of a signal when it goes into my effects loop, but the gate in the rise function doesn't work unless I have the volume/gain cranked on my amp. If I have the pedal at the end of my chain before it goes into the amp, the pedal works just fine. Otherwise, the rise function is one of my favorite effects; you just have to crank the amp, which isn't ideal given I play mostly at bedroom levels.

The Slö is a great sounding ambient reverb pedal, specifically for people like me who can’t play guitar. Some other people will enjoy it almost as much, though, such as: -Guys who dress like they’re going to sell me confectionaries in 1928 -Balding suburban dads who dream of going back in time to 2003 on a Radiohead-related quest -People who still listen to Sigur Ros and want to wow their uninterested wives they dragged away from watching cat videos on YouTube with their uncanny slow D minor playing abilities -Women in their late-20s who own Fender Mustangs and wear suede boots, especially if they have bangs and own Sub Pop singles -A teenager whose grandma thought it was something else -The chick who called me ableist on Twitter’s boyfriend -A guy who tucks his flannel in and has an overly manicured lumberjack beard, full sleeve of tattoos that were popular in 2006, and a barely noticeable beer gut who says “exactly” and “I mean it is what it is” a lot and your wife probably hooked up with him in college when he was a MySpace scene kid, you can’t tell yet and you don’t want to ask because you really don’t want to hear the answer you already in your heart know, then after she gives him a slightly-too-long hug goodbye and says “it was really great seeing you again David, we should do this again soon” you leave the bar and can’t stand it any longer, so as soon as the car door shuts you blurt out the question and find out she went down on xRarrXXPunx87 in the parking lot at Dennys while listening to his emo band’s demo, and you realize your wife probably used to have multiple lip piercings which explains the scars you assumed were from acne, now you’re headed home and she goes “what?” in a really annoyed tone of voice and you go “nothing, it’s just like” and she says “just... don’t. Ok? We were having a great evening” and you start an argument then eventually you’re like “ok yeah, so it’s always MY FAULT, huh?” not realizing that yeah it pretty much always is because you’re insecure and jealous, and you wonder if your old emo band’s demo was as good as his must have been. I wonder if the drummer still has that CDr? -Andy from Pro Guitar Shop /Reverb -People with disposable incomes who post pictures of their generic pedalboards covered in the newest and hippest overpriced clones of clones on r/guitarpedals while I post a rare find of something uncool and get 4 upvotes -Kids whose parents have disposable incomes who post pictures of their generic pedalboards covered in the newest and hippest overpriced clones of clones on r/guitarpedals while I post a different rare find of something even uncooler and get 3 upvotes -Sensitive and angry about it 110 lbs black metal boys- now this is not the best reverb option for your software-based black metal band, but your eight Lurker of Chalice and Vomit Orchestra rip-off projects will certainly find good use for it. Yes, we can tell that’s EZDrummer. -Pink Floyd fans who think they used way more effects than they actually did -That guy from high school who went to Ozzfest 98 and you can’t figure out how he went from point A to point B but then you remember Tool and realize he’s probably been watching the same pedal review channels with questionable ties to the companies they’re reviewing as you on YouTube -People with discogs accounts -People who hate guitar stores because 17 Eric Claptons are in there playing the same scale at the same time on American Strats they aren’t going to buy but tell the clerk they’ll talk to their wives about it later -Some woman who will play with one on Reddit and have an entire sub call her amazing and brilliant -People who enjoy opening bands with eight members at doom metal shows and say things like “that chick playing bass is hot” -College potheads- take note here because you will want this thing to kill time at your parents’ house after you a) drop out, or b) can’t get a job because responsible adults failed to talk you out of being an art or poli-sci major. Not applicable to college bro-type potheads, who now have comfy jobs because reality isn’t fair whatsoever and also moonlight as alt-right social media trolls Before I go, I should mention that the Slö is very versatile, but it’s one of those pedals where you’ll find one or two settings and never deviate much from them. I do find the modulation to be sort of pointless, when you can grab a modulation pedal and have way more control over it (try Walrus’s Julianna for a good chorus, though it suffers from the same design problem I’ll mention in a minute). I also can’t see using the Slö too often in multiple songs, because it’s pretty distinct sounding and you most likely play 50BPM minor chord stuff so it would sound too same-y after a while. The on/off volume is pretty even, unlike so many boutique pedals these days (Earthquaker needs to take note), and I don’t notice it introducing any extra noise into my flubbed notes. It’s built sturdy enough for something with tiny switches, but it really needs to be wider, and having to hold stuff down to activate the secondary function is obnoxious. If buying a pedal used without a manual means that you could potentially not even know about certain options, that’s a poorly designed pedal. This is specifically why I’m taking a star off the review. Designing it even just a bit wider would make adding controls for the secondary functions easy. The previously-mentioned Julianna has the same issue. Using these onstage would be a massive pain if you wanted to drastically change settings, which would take your focus off playing if you forgot to steal your kid’s ADHD meds beforehand again. It’s too bad there’s not a stereo version, but I can’t fault a product for not being a different product. If it says anything, the Slö is so good that I’m considering buying a second one just for that reason. Overall this is a great buy for many different types of depressed people. Recap time! Pros: -It sounds amazing. Like, *amazing*. This thing could have been made from broken glass and human feces and I would have given it a 4 out of 5 based on this alone. -Pretty versatile -Built Ford tough -Doesn’t mess with your tone -Volume is consistent Mehs: -The modulation seems tacked on and you’re better served just getting a separate pedal. Walrus has you covered there though. -A stereo version would be cool, but I can’t fault the pedal itself for the sins of the father. -While it is pretty versatile, you will most likely find a couple settings and stick with those, hopefully using it sparingly so you don’t bore me when I see you open for Neurosis on a Tuesday in like Toledo or something Con: -The secondary function control setup is awful. Just brutally, brutally awful. Walrus, for the love of god, please make versions of your pedals where we don’t have to enter the Konami code to change stuff on-the-fly onstage, or Google what to do at home because if we’re messing with this stuff by ourselves there’s a 4 out of 5 stars chance we’re probably also baked.
