Cool pedal. I've never played any EQD stuff, but they always sound good. Most of their stuff seems pretty reasonably priced, too. Also, Throb Knob is a great name for a hair metal cover band...
I highly recommend trying out some EQD pedals. The Dispatch Master is amazing. I regret waiting over a year to finally buy a Plumes because it's phenomenal as well. Give 'em a try for sure!
I think it's only a matter of time and building slowly. These are some of the best pedal demos, along with excellent quality video and audio, on UA-cam, plus he's a likeable guy. It has to grow eventually.
@@caseybutt5553 Thank you so much. The algorithms can be cruel but fair. Sometimes I have videos that do killer numbers for reasons I can't figure out, other times I sink a dozen hours into a video that barely gets any, and I don't want to do the clickbaity stuff that has left me feeling burnt by other channels. The one that things helps just flat across the board is when people reference my videos outside of youtube. So any time one of my videos gets shared in a facebook group or music forum thread, I see an immediate jump in pretty much every metric. At the same time, I'm just doing this for fun, and I'm always going to let authenticity guide me, but it is nice to get that confirmation back. Thanks again, I really appreciated all of your input on today's video. Makes me appreciate Uni-Vibes even more.
@@caseybutt5553 I totally agree. Plus, there's none of that over the top, artificial-feeling 'UA-cam personality' that a lot of guys think they have to have.
Always liked this one, as it can do quite a few things, and help give one a unique sound. It works really well before a Fuzz Face, and after one, with a lot of options. It’s not meant to be more versatile. Nice video.
That seems to be the most widely accepted one. I think it's entirely possible that work was started and then the connection struck of "Hey, this kind of sounds like those radio noises" because I don't know how anyone could start out designing something with those effects in mind... but still worth mentioning for sure.
THAT is exactly the kind of stuff I love to read. Yeah, it's a very powerful and flexible univibe pedal. I'm sure you'll get the sound you're looking for from it once you experiment with the settings and your playing style.
Best demo I've seen so far! I really dig the pedal when feeded with 18v. It sounds a bit more subtle and gives you the opportunity for an always on setting on the pedal
You clearly have what it takes to go farrrrr beyond 4k subs lol... It's only a matter of time for you to hit some big numbers and help a lot of people, bro. Keep grinding!
This is the best review of this pedal out there. You can tell your genuinely enjoying yourself making these videos! Love how much detail you add too, whether it’s about the history of the pedal type, or the frequency analysis! Cheers man you just earned yourself a subscriber. Gonna go check out your other videos now!
I love the theoretical and historical information, no need to shortcut that. I also love knowing if a univibe really has a light in it. I know I’m not supposed to care about that, but I do. You are the first pedal UA-camr I’ve seen who actually has shown, not just the location of the light source, but showing it in operation. I think that’s really helpful for people who are learning about univibe for the first time. Always love seeing the frequency analyzer, that’s so helpful for understanding what the pots are doing to the waveform. And omg, ham radio operator - your nerd credit just went through the roof for me. Not cuz I’m a ham radio operator (I’m not), but because i worked for 16 years for a large defense contractor and so many electrical engineers there were ham radio operators, and I associate that hobby with a strong knowledge in electronics. Great video!
Thank you thank you! I initially only got my radio license so I could legally use higher power transmitters for POV cameras in quadcoptors. It’s a fun bunch of tech info, and I honestly found the research fun. There’s lots of neat stuff in the radio arts. The Uni-Vibe bulb thing fascinates me. I think about what might happen with different reflective surfaces, or physically moving the LDRs. Or putting a disco ball in there. On The Depths, the voice knob controls the overall brightness of the light. Amazing how it all works together, though I prefer the ones with a real bulb and not an LED. They have a different trailing out that I really like.
@@StompboxBreakdown Same on the fascination with the bulb triggering and wondering what other configurations would do 🙂 That’s cool to know the voice knob controls brightness! Same here, a real bulb is super cool, but golly is that hard to find. Pretty sure my Unicorn is an LED too, but man it’s hard to get a look inside, and I learned the hard way I’m not skilled enough to dismantle modern pedals while trying to fix a bad pot on a Lunastone Distortion 1 🙂
THANK YOU! FINALLY! Thanks for not calling it a chorus! I know the original Univibe and some newer pedals are labeled as such. I just get real frustrated when writers and youtubers call it that, because it's totally incorrect. Anyway, the EQD is a great version. Thanks for doing this one.
Thank you for watching! Yeah, it can be confusing when people say “here’s a chorus” without explaining why it’s labeled that way. Even moreso with tremolo and vibrato, and phase-based vibrato and then rotary enters and mix and…
thanks for another great deep dive. yeah, i just dad-joked in a topical way. aw jeez i just did it again here's the real grist: i love love love the format you've developed on your channel. i can literally see storyboarding and/or film scripting work embedded into your work. technically, your show is just perfect, in the way you lay a ground base, bring the viewer up to speed with technical info (graphics, etc), to the nuts/bolts (camera focus, lighting, shot composition, voice audio, music audio) of piecing it together. coming from a background in teevee (i was a technical director at a local NBC station for some time), it's *incredibly* satisfying to see a well-thought out and executed presentation. as a musician, i enjoy the content, as a research geek, i love the hard data, and as a slave to proportional aesthetic, i have to say that your style of production ...just fits well with me. it's my hope that your channel flourishes and you continue to enjoy your work here. i'm a fan of your work. alright goddammit i'll stop blowing smoke and work on my dad-joke standup routine further also, the diminished chord at 6:21, combined with that classic Dean Ween-esque phase, combined with the whole note rests afterwards? i quite literally sang "...reaching out, i can touch your face.." (see Ween's *Back to Basom* if you don't know the reference, but i suspect you do)
Wow... wow.... thank you so much for that, it made my (up until now, incredibly crummy) day. I do some video work as part of my day job, but I'm bringing more to that role from this than vice-versa. Plus, being able to empathize more directly with the audience really helps... I get to make exactly what I'd like to see, even if it takes time to learn those new techniques. It really is amazing what's possible with fairly easily-acquirable gear and software, and I'm thankful that youtube and the audience I have seem to appreciate some level of production, pacing, composition and all that stuff that you don't come right out and ask for, but makes watching all the more enjoyable (I hope). Right now, every video I put out has a nice balance of "Ok, I'm following my usual process" combined with "Well I've never done this before but we'll see" and I hope I can continue with that. It's a fun challenge, no doubt. About the diminished chord and the Ween song, without a doubt, one of my favorite things about this channel is making something up and then hearing "I liked that jam, it sounded like ...." and I just keep discovering new artists and songs that are totally up my alley. I've listened to lots of Ween, but I might have missed this song before. They're so good and when I heard the spot you're talking about I started cackling. Hahaha, thank you so much for that, this is what it's all about. Have a great one, @JammyPants
This must be the first time a video helps enjoy more a pedal I already have. The first thing I'm going to do is run it on 9 volts, from the 18. I guess I naively believed that 18 was just automatically going to be better. I should have experimented.
I have owned the V1 version of this pedal and now have the V2. Also have a JHS Unicorn V2. I love the Depths, just has its own thing going on. It’s my go-to for vibe tones. Great video, nice to see this pedal get some more coverage.
@@adamkrauss303 I recall thinking the speed range changed - it seems like my V2 won’t go as slow at the minimum setting as my V1 did. Otherwise I think they sound identical, no difference in actual tone.
@@StompboxBreakdown have you done the ED Spatial Delivery? ...I was scrolling through your videos looking for it but got stuck at the SY-200 😆 (I have the SY-1) and am currently shopping for a Leslie sim.
Univibe is probably my favorite effect and finding the perfect univibe is so hard every one I've tried has a different quality I like and I wish there was one that had all the good qualities in one some don't even have the vibrato mode like this one and finding one that both modes are great is hard to find and univibe is a very expensive effect type to get into.i wanna try the new vibe that has a bunch of sliders to draw your own wave shapes with but that things like 800$?
I’m with you… love, love univibe. Maybe JHS will do a univibe pedal ala the Bonsai/Muffaletta/PackRat and give us 8 or 9 classic variants. That would be amazing! I do love The Depths (&EQD), my only wish is that it had tap tempo. Keep rocking!
If you ever try an EQD Night Wire, I’d love to hear about how much they overlap. Honestly the overlap between any harmonic trem and univibe would be interesting to compare
Oh man, something else on my radar now. I was actually pretty amazed by the harmonic trem mode on the Supro tremolo, I thought that sounded vibe-esque. I’ll keep an eye out.
I've actually got one! Last time I put it on the board, I wasn't getting what I wanted out of it, but maybe I'll revisit it at some point. Thank you for the offer, though!
Just returned a JHS Unicorn because it added a harsh treble to the sound and seemed to have a square wave form. Pretty lousy. Sorry I sold my big 18V Dunlop. I like the sound of this but I wish it had more control options and a Vibrato mode.
... unless it's vibe. Example: Fuzz>vibe>compressor>OD>distortion>Muff(it gets to break the Fuzz First rule because it's awesome)>another OD>clean boost. That's my board layout and the consensus vibe placement. Who am I to question Jimi Hendrix's wisdom? He played Woodstock and Monterey, I didn't.
It's a capable pedal, but it still doesn't have that "double pulse" throb of the old Uni-Vibe units. If you listen closely to a "real" Uni-Vibe" you'll hear a distinct heartbeat-like double thump in the low-end. This one is much smoother, like a phaser that's sweeping into the lower registers. To be fair, some of the earlier Uni-Vibes were like that, but the later units, with their famous "heartbeat" were the ones I think most people consider the "holy grail". I've worked a lot with the Uni-Vibe circuit and my guess is that Earthquaker went with the schematic that came in the original Uni-Vibe manual and is readily available on the internet. This pedal sounds like that circuit. That circuit, as it is, won't produce the double pulse though... it's smoother.
Interesting, thanks for the insight! Are there any more modern (and maybe more easily attainable) pedals that get the double pulse type effect on the bass notes? I’d imagine a lot of it comes down to what’s being played and how the pedal is set up.
No, it’s the 68’ and 69’ units, that most want. The 68’ was what Hendrix used, and they tweaked them, because each unit could have differences. The 68’ is a deeper throb, while the 69’ and 70’ units, were what Gilmour used for awhile, and still goes to off and on. Most of those companies just didn’t make that many in the 70’s, after phasers and other effects came around. One _can_ get the throb you speak of out of The Depths, it’s just very tweakable. Not going to sound as deep, as a vintage circuit, but it can sound like a great Uni Vjbe. Check the Wampler video, in which they put The Depths, in front of a Velvet Fuzz, and he gets a perfect Hendrix, “Hear My Train a Comin” effect.
@@StompboxBreakdown If you listen for it you'll hear it in lots of online demos. Instead of going "woo, woo" the Uni-Vibe will go "wa-woo, wa-woo". :) To many people it's the mark of a "true" Uni-Vibe, but that isn't really so because there are different flavours. I know that the Fulltones get it, I think the Voodoo Labs version does too, as does the EHX one. There are probably lots others that don't come to the top of my head. People think it's caused by the asymmetrical skew of the low frequency oscillator but that's only part of the story. The Uni-Vibe LFO is not a perfect sine wave but it isn't that off. The bulb itself has a non-linear response to the LFO, so it isn't linearly tracking what the LFO drives it with anyway. That's a part of the throb, but it isn't alone what causes the heartbeat-like double pulse. The double pulse comes from the filter notches overlapping as the LFO sweeps along with the 'poor' tracking of the bulb. None of the phaser and LED vibe pedals do it, that I've ever heard. The 'ideal' circuit that people know of produces an ideal, smooth phasing like I'm hearing from the Earthquaker. Again, it isn't a matter of bad or good, or right or wrong, it's a flavour. Personally, I like the double pulse because it makes me feel like Robin Trower. :)

Is this pedal good for classic Hendrix sound?
This pedal sound best in fx loop or front of amp? I am using FX loop and when i kick in the distortion its an ear bleeding mess.
I’ve never had good luck with pedals in the effects loop, other than maybe a reverb. I’d just throw it up front and rock out.
I did not like The Depths. There's too much nonsense going on. This video made me understand it better though.
Sounds Good Would be nice to have set up Ramp Up or Down floor button
