Earthquaker Devices The Depths

Direct from the source:

Ahoy! Welcome to your new Depths Optical Vibe Machine! The Depths is our take on the classic optical vibe circuit. Now you can swab the decks with the same lush, pulsating, three-dimensional swirling sound you know and love, with some modern accouterments for all you land-lubbers out there.

The Depths is optimized for use with all kinds of instruments, pickups, and to play well with dirt, so nobody’s left waiting on shore. If it’s got a ¼” output, plug it in and get deep!

 In addition to the classic vibe controls, the Depths features unique controls for “Voice” and “Throb.” The “Voice” control adjusts the midrange focus of the Depths, which is perfect for tailoring the effect to your particular instrument. Clockwise, you’ll hear a fuller sound with a low-end focus. Counter-clockwise, you’ll hear a thinner, spikier sound with a forward upper-midrange bite.  The “Throb” knob adds a hefty subharmonic low-end pulse to the vibrato signal, which is especially useful on synthesizers and the bass guitar. It sounds great with a little bit of dirt on the neck pickup of a guitar, too! This works best with the “Voice” turned counter-clockwise for a warmer tone.

The Depths’ “Intensity” and “Rate” controls are dialed in to give you the classic optical vibe sound at more modest settings, but dive in deeper and you’ll find anything from a smooth ultra-slow warble to sharp, speedy bursts! Also, the “Level” control has tons of output above unity on tap to combat the perceived volume loss of most vibe pedals, so your tone is always above water. And, if 9v isn’t enough to keep you afloat, the Depths may be powered at 18v for a stiffer tone with more headroom and sparkle.


We've got 2 layouts for you.

Layout 1: We've got the the LFO off the main board to hopefully prevent the dreaded LFO tick. Should fit in a 125b like the original. Downside is that there is more offboard wiring you will need to do.

Layout 2: Slightly larger board, with the LFO on the main board. You shouldn't get any ticking, and you'll save on having to deal with the extra offboard wiring.

  2. Verified bottom layout! Had to use diffused LEDs as for some reason when i turn up the voice pot to max it blows the clear ones. Used GL5549s for LDR and diffused yellow LED. Need to try some different LED colours and maybe LDRs as its not quite perfect yet but pretty damn close.

    1. Scrap that about the clear LEDs. I must of had a couple of dodgy LEDs as tried again with a clear and it worked fine.

    2. Schematic is in the Forum section.
      Thanks Gavin!
      Does it sound like the video?

    3. It's hard to say as these guys can really play and there setup is probably very different to mine but mine definitely isn't as clean sounding but that may be the choice of LDRs or LEDs. Its something i need to experiment with when i have time. Oh, thanks as always for your sterling work and all who contributed, Cheers.

    4. Ok, so the noise seemed to be from the LED attached to the pedal (used an Ultrabright) as i hadn't covered the LED/LDRs. Normally that isn't a problem as I like my studio quite dark. Covered the LDRs/LED with a bottle cap and it cleaned it right up. Now sounds like the video, pretty much.

    5. Schematic is not in the forum section. At least not in any of the threads the search engine comes up with ....

    6. not sure how you're searching in the forum will, but it's under the requests section, and it's on the first page of the thread.

    7. OK I found it.
      Thanks for the quick reply, Zach!
      Honestly, I tried this again. If you enter the title to the layout as posted above the 3 search returns that come back don't include this thread. It's probably because the thread with the schematic has a shortened title (with the initials EQD) instead of using the full title; Earthquaker Devices. I guess I should have figured this out myself.
      Thanks again Zach,
      Will

  3. Maybe try a GL5528 or GL5537? 150k-10M for the 5549 is quit a big sweep vs a 15k-1M for the GL5528.

    1. Hey Arnold, Thanks for the suggestions. I do have these and will give both a try out. Will let you know the results when i give them a try.

  5. How do you guys feel about a 2n5088 as a replacement for the MPSA18? Tayda does have them, but I just did an order a week ago and it'll be a while before I can do another. I've got everything else.

    1. nope. mpsa18 have gains in the 10000 range. you should be able to grab a few super cheap on ebay for now if you don't want to wait for an order from tayda, in fact thiashine on ebay is tayda with shipping basically included. it's always good to have mspa18 around, so i would get a few now for this build, then on your next tayda order add a bunch cause they're still super cheap.

    2. Socket and try. It might work, as the MPSA18s are here the LFO, so the different hFE might not be a problem. But I do agree with Zach: MPSA18s are always handy, so it makes sense to stock a few in your parts box.

  6. ...and that's Layout 1 with the daughterboard verified too. No ticking and fits in a 1590B!

    Cheers lads

  7. How do you guys think this compares to the Runoffgroove Tri-vibe?

    The playing in the demo is fantastic. And here I thought I wasn't a fan of vibrato pedals :p

    1. I've built this, the Tri-Vibe and Madbeans Wigl. So far I like this the best but I need some time to compare.

      The TV is great but I found I only used the Univibe setting so I didn't want a BB size pedal on the board when I could build a dedicated vibe in a B. So I built the Wigl. Another good one but not as shifty as The Depths.

      Need to put this on the board now and see how I get on.

    2. The Tri-vibe has a vibrato mode and a Phaser mode a la Phase 45, which is a subtle, vibe-y phaser (mode 3, "whirl" is a blend of both). The Depths seems more like a straight univibe type circuit which will have more throb and movement than the phase mode of the tri-vibe (swirl).

  8. About ldrs i remember pangea project, a wodoo vibe clone, using 3 5549 and one 5516. Wich ones have you used withthat one? Are they working properly? Great schem and layout by the way!

  9. Seems like it doesn't go very slow. Kind of medium speed to fast.

  10. I'm wondering if there's a cut beneath the LDR on row 'A' of the first layout? I'm not getting any throbbing with my build.

  11. Has anyone succesfully built the 125B version? I built it up, but am getting no signal passing. Audio probing it, I get signal to the TL074 (pin 5), but nothing after that. The rate, intensity and voice pots all seem to work, so its just a question of why my signal is not getting through the first IC.

    Thanks

    1. i believe ciaran verified that one. post up pictures, description of the problem, and your voltages in the debugging section of the forum.
