The Oceans Abyss takes over from the Oceans 12 as EHX’s flagship Reverb Workstation. The Oceans 12 has 12 Core Reverb Voicings - including Echo and Mod - which are replaced on this more potent model by numerous additional Delay and Modulation Effects options - where you can create your own signal path using all those effects.

 

So this pedal is more like the Meris Mercury X and Strymon NightSky - in being a Sound Design device focused on Reverb - but with a number of additional extras in the mix. I currently have the BigSky MX on my board - which is very much my speed!

 

Those slider controls on the Abyss are certainly really cool to have - but since I also have the Eventide H90 on the board - I’m not sure I would necessarily make use of all those optional extras - while there is some advantage of having those all onboard the same device. My current rig has 52 pedals in its signal chain - which I can already combine and route in several different ways - for instance - I have the 3rd port on my Parallelarator available for syncing any of those effects pedals of mine in parallel - so I don’t really need all those extra signal path options that come with the Abyss.

 

I always say that you need to pick your own lane really - find your own speed for the sorts of effects that match your needs and sensibilities. I always keep my options open - while I remain to be convinced that I should sub out my BigSky MX for this Oceans Abyss. Based on my experience with the Meris LVX I already decided that the Mercury X wasn’t really for me. Meris definitely pile on the extras - so those pedals are much more like Multi-FX Workstations. Lots of players who love those effects - like Jake @ TheGigRig - love them for all the included extras - which they wholly make use of - while if they had my rig - those kind of just add complexity - and somewhat duplicate abilities that I already have on the board - to most degrees of operation.

 

You need to decide whether you’re more a Creator of Effects or Shaper of Effects - each one requires its own mindset - and I feel I’m more firmly lodged in the latter category. If you’re more of a Sound Designer as such - then the Oceans Abyss, Meris Mercury X, Empress Zoia, and Poly Beebo should be more down your street - for the rest of us - we have slightly more on-rails pedals - like indeed the BigSky MX - albeit that one does allow you to import your own IR’s - so the sky’s kind of the limit there too from a Reverb perspective. While you don’t get those extra Delay and Modulations included like on the more Sound Design type devices.

 

When I first saw the POGIII and this Oceans Abyss - I always thought they looked a little larger - but they’re both actually near enough the same magnitude of dimensions - 18cm x 14.6cm x 5.7cm vs the 17.4 x 12.7 x 6cm of the Stymon BigSky MX - so the Oceans Abyss is only very fractionally larger!

 

As always - I never say never - and maintain an open mindset - I’m always open to be persuaded to head off in any divergent direction - I just need the appropriate stimuli to pique my interest!

 

The Oceans Abyss is most definitely a very decent proposition with potent capabilities - you need to decided for yourself whether it meets your needs - it certainly has a very cool central VDU control screen and overall control topology and interface. This is a particularly well thought out and well appointed device - reasonably priced too @ $495 / £475 - I’m not seeing any EU prices yet - as this pedal is not yet stocked at Thomann as of writing this article! (Which tends to be my reference for EU pricing).
