Quick preamble: I thought I'd put this in a separate thread from my original "Looking for a small(ish) multi-mod" thread, as I may be going full heretic and turning my back on multi-mods and returning to separate pedals for the effects I use most, and forgetting the rest. The following pedals have to rival and best my Wampler Terraform to win a spot on the board.

Looking to achieve the following goals:

1. Find what I feel are the best examples of that effect I can, which transcend what a combo pedal can provide. Sound quality and character are top of the list.
2. Keep bass alive—effect shouldn't swallow bass, or should have a mix knob or filter.
3. Should be able to sound barely there if desired. I often record this way. Phase 95 won't be able to do this, of course, but I have to try it. I may add other phasers to this list.

I read about 40 threads and took many of the favorites plus the Source Audio Lunar suggestion many people gave me on the above thread. The pedals, a mix of digital and analog, are all arriving various days this week, the first two choruses got here today:

Choruses:
MXR Bass Chorus Deluxe
Walrus Audio Julia
MXR Analog Chorus
Keeley Seafoam Plus
Jam Waterfall Bass
Source Audio Lunar (I'll compare the sounds from the Gemini)
Neunaber Inspire (I already own this, so I'll compare it to the rest)

Phasers:
Source Audio Lunar
MXR Phase 95
Earthquaker Devices Grand Orbiter v3

There were a few that were obvious choices (Providence Anadime, Bass Clone, etc) but I already spent too much money, which I already can't wait to credit back to my credit card when I'm done testing. Also, the Anadime, though it looks like a very solid chorus, didn't appeal to my ears in demos. There are other interesting boutique choruses and good ol' Boss ones, but I had to start somewhere.

Admission of guilt: I have a bias against EHX that I can't explain. I know that of the 6-8 or so EHX pedals I have tried in the past, none have ever won me over. I keep trying them, but they leave me cold. So I'm not trying the Bass Clone this time around.

When they're all here, I'll try to do audio files. No promises.

Since they are arriving in dribs and drabs, I'll say something about the two that came today:

MXR Bass Chorus Deluxe: A very popular pedal on TB. It's a very mild chorus pedal. I would say it's like a chorus designed for bass players who are told they need to have a chorus but who don't actually like the chorus effect. There were two features that really made this look like a winner: an Intensity knob (read: mix) and the x-over button. I found the x-over to remove at least the bottom half of the chorus signal from the dry. A little too much in my opinion. The amount of effect removed was really brutal, so you were left with just a chorusy sheen on top. It didn't work for me. Intensity worked better. But it was so subtle, and I see how that would work for a lot of people. Not for me, though; I want that full-on "One World" tone off Brothers In Arms. I was turned off this pedal enough that I barely twisted the Bass and Treble knobs before deciding this one wasn't for me.

There was also a fatal flaw: There is a LOT of distortion with the effect on. I'll make a recording of it. I already had a very similar problem with a MXR Vintage Bass Octave, and got zero support from MXR when I enquired about it (until over a month later, after I'd returned it, having read several accounts from others about the same thing). As soon as I heard it, it all came flooding back: I think this is a larger MXR problem, because it keeps happening. That would be unfair if this hadn't happened before to me, or if I hadn't seen reports of distortion from others. Confidence shaken. There is a cheapness about some MXR pedals I've played, but others are fine. I played a Bass Octave Deluxe for years with none of these problems. MXR are affordable, and usually sound great, but are a mixed bag. MXR have managed to piss me off more often than not and even today I found I would not be spared. Let's hope the Analog Chorus makes right.

Then I pulled out the Walrus Audio Julia. For only thirty dollars more, you get a work of art. Not only does this thing look gorgeous, but all the pots, the switches, they feel expensive. The only thing more expensive than the feel is the sound. I see why so many people have recommended this pedal. Julia manages to pull off a trick that is very difficult to do: it has tons of character while also sounding rather "HiFi". Everything on this pedal seems really well-judged. The D-C-V knob blends between Dry and Vibrato, with Chorus at noon. The Lag knob really takes you from "static resonant frequency", mellow chorus to full Technicolor seasick. You can clean it up two ways; crank the Lag and drop the Depth, or crank the Depth and keep Lag low. The Rate isn't fast enough for full Scofield-style Leslie effects, but you can still get a lot of fun, wavy goodness. I find the Rate range to be just right for a bass. There's a toggle switch for sine or triangle wave, which is subtle, but you get that extra lumpiness from the triangle, and I'm glad it's there. I really connected with Julia. It gave me everything I asked it for, and even at full chorus blend mode, you never lose any bass; it just sort of "widens" but never thins out. There are more to come, but Julia is the one to beat.

Seafoam Plus and Analog Chorus come tomorrow.

Just curious - was the Julia an issue without a crossover?
Maybe I was so into what I was hearing to think objectively, but no, I didn’t hear anything bad. I was surprised how well it held up. The low frequencies seemed to “smear”, which to my ears didn’t hollow the note out as much as you’d expect. I will upload a comparison with dry. For the moment, I’m impressed with strong bass from the Julia.

(Later) *Having tried it again*, my earlier comment pretty much still stands, but is it going to be impactful on the same level as if a chorus wasn't turned on? No, it can't be without simply not affecting the low end. It's more diffuse, as you might expect, but it's maybe the best example I've heard so far and I would not be bothered by it.

While I'm an MXR fan, I had the same the experience w/ the bass chorus deluxe minus the distortion problem. Too subtle to be heard in a mix. Their big yellow chorus is a much better chorus for bass. I don't like chorus on bass much, but if I had to pick one I'd get the yellow one.

Well, I'm heartened to see the blue Analog Chorus doesn't suffer from any of those problems, be they incidental or by design.

I made a simple loop to test how much loss of low end there is from switching every chorus on. All choruses (I'm still missing the Waterfall Bass and the Gemini (really a Lunar) at this point) have a similar slow-ish rate, and the depth is up full on all. If the pedal has options, they are listed in the file names.

The problem with evaluating this is that some of the pedals do some trickery in order to "stay loud", by artificially adding gain in one way or another, and this will fool the ear into thinking you aren't losing bass, or in some cases the pedal is actively adding bass to compensate:

Notes:
  • The Analog Chorus is close to 2dB hotter with the effect on, at full Intensity and EQ "flat". Something's going on under the hood.
  • The Seafoam Plus adds extra gain to the dry signal: the pedal on with the mix knob all the way dry (ccw) is 5.3dB hotter than bypassed, which is really a lot. When you pan it to 50/50 it drops enough so that it makes up the volume lost from the cancelation of the effect.
  • The Bass Chorus Deluxe is 1.3dB hotter with the X-Over on then with it off, for some reason.
  • Julia doesn't do any compensation, and its three settings I recorded will sound different because the Lag knob (shifting of the LFO in time) is in a different place, canceling frequencies differently.
  • Inspire is the clear loser here. Bass kinda goes away. Setting is the primary "Tri" chorus. The Tone knob on this pedal lets you retain some bass in the full CCW position, at the expense of high end detail. Because of these results, I may remove this pedal from further comparison, put it on the guitar board where it belongs, and let it dream about Mike Landau going forward.

Here's MP3s for the following:

I love my Julia. It’s versatile but not busy, easy to find useful and subtle modulation. I agree the Walrus products I have feel very well built. Sounds great on guitar too FYI.
I have been running digital stuff separately and was considering a Gemini to go with my MIDI junk so you’re gonna have to review that too. Sorry.

It's all part of the plan, only the same noises will be coming out of a Lunar, Gemini's twin in another case. Rest assured.

Today's impressions:

MXR Analog Chorus: This is much more like it compared to the BCD in my opinion. The chorus itself is pleasant-sounding, pretty warm, but you have these two treble and bass cut knobs, which you can sculpt the effect with. I found the Treble knob more useful than the Bass, which I think would have been more useful if it was a simple HPF for the effect signal only, before it gets blended with the dry. In fact, I'm not really sure why a simple HPF isn't standard on every chorus made. Although the build quality appears the same as the BCD, it feels more robust somehow. The rate never goes super fast, and the depth is also fairly moderate. You can't make this sound as effected as some of the others, but for a basic chorus, it sounds great on bass. Intensity is useful and welcome. For some reason, the bass and volume both increased when turning it on, so it really wants to be thought of as a pedal that doesn't lose authority and low end. I found that to be a little gimmicky.

Keeley Seafoam Plus: Here's a great-sounding pedal that has some tricks up its sleeve. There are three effects per mode, and the best of the lot is the ADT (Automatic Double Tracking) or Dimension. Dim. is a great alternative to standard chorus, and is less swirly, and I've always been a fan. There's a handy reverb knob in the Dimension mode if you want it, or, switch to Bass Mode and the Dim becomes a flanger, and a really nice one. Its main chorus sounds pretty much like every other chorus, but there's a knob to boost or cut 500Hz or 100/200Hz depending on if you're in regular or Bass mode. I wouldn't say this Chorus is that unique, but it's a really solid, classic offering. The program I didn't know what to do with was the double-chorus, where you can control the depth for both HF and LF, plus a variation in Bass Mode. I'm glad Keeley decided to throw such a bone to bass players with the Seafoam Plus, but the problem with Bass Mode as I see it is that aside from it being locked away inside the case, it steals Dimension from you, so if you want to have a more bass-friendly tone control for the Chorus mode, you have to get rid of Dim in favor of Flanger, which I'm not willing to sacrifice. If only it wasn't a DIP switch, and just was a little toggle on the case somewhere, it would make all the difference. The other missed opportunity in providing a "bass mode" is that once you throw that switch, the effect path should get HPF'd around 100-150Hz across the board, but I don't hear or see any evidence that it does. One other winning thing I really liked was the other DIP switch, which cuts the treble response across the board, which is a great option. I played it both ways and couldn't decide, but liked the sound of the darker effects a lot. I see why it's popular here and I could be happy with this pedal, especially as you get a lot for your money in a small package, I just have those small reservations.

The EQD Grand Orbiter showed up and I gave it a brief whirl, but not enough time to report. That being said, I really thought it made a great noise, and had very thoughtful controls. More on that later.

I often switched back and forth from the Terraform, and although the TF does a great job at many things, I could now hear that Wampler voiced the effects of the Terraform in ways that I think anyone would have an opinion about. With these pedals, I could recognize the Terraform's overall tone shaping, which is different per effect, whereas these standalones were much closer to the sound of my basses, only with an effect.

There is a disease that is causing bad decision making to occur among pedal designers. I'm talking, of course, of the dreadful "put the power jack right next to the input or output, but not on the top where it belongs, but on the damned side of the pedal" phenomenon:

Seriously, guys. Knock it off.
 
Yeah, it's a sickness.

Hey Lunar/Gemini/Mercury users: What's the deal with the factory Chorus settings in Neuro? I can see the three factory settings for the Gemini, but unlike every other preset on Neuro, I cannot copy or burn those three to Lunar. I'd love some help if anyone knows how to get those three starting points into it.
 
Great analysis! I just bought a Jam Ripple phaser, very subtle, but just adds that little bit of magic to the tone. I'm curious how the Waterfall will perform.

Well, the Waterfall (I'm due for an update to this later today) is probably my front runner at this point and I was wondering about the Ripple. It may be a Ripply Fall for me in the end, but we'll see.

There will be some sound examples later, which I recorded last night.
 
I was calling this the "Wet, Medium Speed Test".

All I'm doing is trying to match the speeds on all choruses, use about a 2/3 to 3/4 Depth and compare the general sound of each. I tried to take a photo of the controls for this particular recording (with a couple failures).

Which do you prefer? I know what my front runner is, I think. I realize this is a pretty Depth-heavy example, but that lets me know what the thing is made of, considering I'm going to usually play it down.

One caveat about the Lunar: I'm having difficulty getting the factory settings for the Gemini Chorus downloaded into it (something about my unit or my system probably, but they're looking into it) so for this I couldn't use the basic settings and tweak from there, so I just did it all manually, tried to get something that sounded similar to the rest and took screenshots of Neuro for the three chorus effect types. Will this pedal sound different one I get the problem resolved? I'm not sure, but I can tell it seems to have a unique sound. So far, I'm hearing more feedback in the Lunar chorus examples, even when I roll that knob off completely. It might be it's own vibe or it may be an anomaly. We'll see.
