Modulation Powerhouse...

The Greenhouse Effects Logos Chorus-Vibrato is a cleverly designed and beautifully executed modulation powerhouse with 3 chorus modes plus a classic vibrato effect accessed by turning the Mix knob to 100%.

What's more, an expression pedal input makes the Greenhouse Effects Logos even more controllable and versatile on the stage.

If a wealth of chorus is what you are after, the Logos has it: pitch shifting, multiple voices, LFO, feedback, envelope detection, waveforms, distortion and even reverb are blended together and rearranged to make 48 different combinations of incredible modulation.

The pedal's party trick is its "Logos" mode, which is a chorus with an LFO featuring various pitch interval settings and added reverb. As Roy at Greenhouse Effects says, "it feels like an organ player is playing along with you in a large hall!"

The 3 Chorus Modes:

  1. Order Mode: Classic chorus with up to 8 cascading voices, normal to extreme depth, DSS: Max Depth for noisy chaos. Hidden feature: Automated rate.
  2. Chaos Mode: 8 chaotic modes of pitch modulation, envelope LFO, waveforms and double voice. DSS: Max Depth
  3. Logos Mode: Beautiful, dreamy chorus with 8 combinations of modulated intervals, octave up/down, 5th intervals, and flanger-like modulation at lower settings. This setting includes a hall-style reverb for added angelic ambience. DSS: Max Depth for noisy chaos. Hidden feature: LFO off. 

DSS Switching

One genius implementation is the DSS (Dual Switching System) , which gives you access to secondary functions in each mode when you hold down the footswitch for more than 200ms. There are also "hidden" features for each mode, accessed by maxing out the Rate control.

The Logos is another example of the great work Greenhouse Effects has been doing combining analogue circuitry with digital controls. Sit down with this for a weekend and explore all the sounds it has to offer - there's a lot to discover!

Features:

  • Multi-mode chorus pedal with vibrato setting
  • Unique "Logos" mode
  • Mod, Depth, Rate/Sens/Pitch & Mix controls
  • True bypass

Great sounding, massively versatile chorus

I've been meaning to add a dedicated chorus pedal to my board for a while now and saw Ponderer Sounds' YouTube review of the Logos which really piqued my intereset. One of the first pedals I ever owned (back in the late 80's) was a DOD FX65 which was a great dedicated chorus. Sadly I sold it way back and had never really bothered with much in the way of modulation since then... When the pandemic hit, I'd already started playing more guitar again and since I was still working but not having as many outgoings as usual, I decided to revive my interest in effects and set about putting together my first pedalboard. Amazed at the breadth of makers and effects available, I brought together some classic brands like EHX and BOSS with newer and smaller, hand-wired pedal makers. In addition I've developed a taste for more ambient and electronic textures in my sound so when I saw the Logos it really looked as though it fitted the bill. Having played it for a week or so now I can confirm that it oozes quality and is a sturdy, well-made and very adaptable modulation effect. Having reverb, vibrato, LFO with different waveforms, envelope control and pitch-shifts with the addtion of an expression pedal add so much potential for lovely dreamy, spacy textures. There's also the option to go crazy with the Chaos mode and have portamento pitch shifts with massive modulation to create huge wobbly alien sounds. The Order mode is a very versatile chorus effect with a LOT of depth and tweakability including wetting out completely to a vibrato but also flangey-style sounds at the other end of the spectrum. There are numerous bonus features like LFO ramping and of course the Dual Switching System which can give your chorus a little nudge or tip the Logos through psychedelic wormholes into cosmic mayhem...

So, fantastic pedal and great service from Boost pedals. Communicative, prompt delivery, no issues - highly recommended, would use again.

So much more than a chorus

I’ve never been a great fan of chorus pedals, the 1980s put me off. I am, however, very interested in using my guitar to make as many different sounds, textures and moods as possible. I have a huge pedalboard for that reason, but chorus was never a part of it. Phaser? Yes. Chorus? Nope.

Enter Logos. It was the vast array of settings that drew me in, and a couple of demos that proved that chorus in the traditional sense was not really what this pedal’s about. It’ll do chorus, for sure, and a few distinct and interesting versions at that, but the really interesting noises veer far from the ‘light swoosh’.

The 3-way mode switch in the middle of the pedal takes it from Order through Chaos to Logos, with arguably the most fun sounds to be found among the Chaos. Rhythmic feeding-back triangle or square wave sirens hide in these depths, choppy waters that threaten to sink your song and pop the sonic armbands that have kept your playing afloat. After a few weeks’ intense trialling I’ve begun to be able to predict roughly what might happen at the turn of a knob, and I’m even sometimes correct.

‘Order’ is the more traditional and pretty set of settings for chorus. Here are the bass settings for anyone doing covers of songs by The Cure or Fields of the Nephilim (yes, it’s great on bass, especially goth bass!). Even though this is the tame end of the pedal there’s plenty of weird on tap.

‘Logos’ is a fabulous group of settings, adding pitch shifted modulations and a vast reverb for some super-shimmery soundscape action.

The footswitch itself needs a paragraph of its own. It’s nice and soft and non-clunky, which is lovely, but it has an extra feature called DSS. This enables you to max out the ‘depth’ setting by holding the switch down for longer than the usual on/off type of click. This can take you from a regular chorus to a wild-west rodeo ride type of effect, a real motion-sickness button. Lots and lots of fun.

I haven’t used it with an expression pedal yet; it’s something I’ve never bothered with but I’m beginning to see the point. With a pedal like Logos there’s an awful lot of expression available.
