  1. that's a great layout Alex! and a really nice delay.
    in the vid the repeats control does not oscillate. am i right?
    that's the first time i'm seeing that with a pt chip. do you think that leviathan works that way too???

    mmm... i think i'm gonna give it a try anyway...i said no more delays but...!!!

    1. Hi Savvas!
      From what I can see Brian's schematic is identical to the original except a few components values.
      I suppose it should sound the same.

  2. External mod board? Please explain

  3. If you want to add an extra modulation circuit of your choice.

    1. Hi Alex, if i were to add extra mod circuit, delay 2-3 goes to the IN of the mod board, and where does the OUT from the mod circuit connect to? thanks!

    2. There is no input in the extra Modulation board.
      Just one output that goes to Delay 2&3.
      This is an example:

      Also, this Mod Daughterboard from Mark might work:

    3. Thank you very much Alex... learned a lot from you guys. Will start to build this by the weekend.

  4. Nice! ;) What modulation works better? (Without Vactrol)

    1. Try using the modulation circuit from Madbean's Dirtbaby & ZeroPoint Mini, it works for me and I have the option of switching from short chorus like and a wider modulation.

  5. Verified! Nice delay. Really like the repeats on this.

    1. Great! Cheers Gavin. I'll tag it.

    2. yeap....i've build that one too.
      the tone pot does almost nothing to my ears..maybe it's my guitar, or amp. i don't know. also level acts more like a mix control as i expected.

      i'm working on this for the last week.i drew and build an other perf bord layout just for fun cause i'm accidentally stack with 5 big boards and wanted to use them. it came out relly small(12x24), but too noise, so i've rebuilded it on vero.

    3. To comment on that tone pot. My tone control on the deprofundis built also did (almost) nothing to my ears.

      Delete
    4. yeah...i'm sad about that...i really wanted to box this...but as i see it, my deep blue delay is much better at this point.. i'll keep the board in case we fix the problem though..

    5. You could try upping the 68n on Tone 1 to 100n or more....OR increase the Tone pot to 20K plus. Both changes "should" dramatically alter the corner frequency of the LPF.

      Delete
    6. 20k pot + 150nf...still nothing on the tone response... maybe (not sure)that mods changed the frequence that the pot "should operate" , but i can't hear any response from the pot

      Delete
    7. Hi, did you solve the problem with the tone? I found there's one cap missing in this version compared with the Madbean version, could that be the problem?

      Delete
    8. Which version? The layout? I'm quite sure it matches Madbean's schematic. 29 caps. Which cap would be missing?

      Delete
    9. I'm sorry! I was missing the 1n one from the sixth pin of the tl072, my mistake.

  7. How to make it sound brighter?

    ReplyDelete
  8. Where do I solder LED -? I don't see any LEDs in Madbean's schematic..

    ReplyDelete
    Replies
    1. That's for you bypass LED indicator. Wire it to your stomp switch like you would on any other build. The 4K7 to the left of LED+ is its current limiting resistor. Adjust this value for your preferred brightness.

  9. I'm still a noob with building pedals, so please excuse the question, but has anyone put this into an enclosure yet? I see Madbean is calling for a 1590BB, but it looks like it **might** fit in a 125B. Any thoughts? Thank you for any assistance offered.

    1. In theory the vero could fit in a 1590B enclosure.
      Should have no problems with a 125B.

  10. I finished this delay and added the modulation daughterboard from the Deprofundis post, it works fine, except the switch gives modulation only/delay only/delay only, I tried swaping time 1 with time 2,3 but then I obtained modulation only/delay only/modulation only. What would be the problem?

    PS1. I postred this issue there but have no answer yet.
    PS2. Thanks for this blog and sharing so much info!

    1. Maybe it's not exactly what you were asking, but this helped me add the modulationon board you mentioned on a DBD and have modulated repeats.

      Look for the answer by slacker about the rebote, towards the end of the page.

      Delete
    2. Thank you! I did what slacker says there and I finally obteined modulated delays, but unfurtunately the other positions of the switch did no effect at all. I tried several ways of wiring the switch and I couldn't get the three options. I think I will try with a 6 pin switch on/off/on. Thank you again!

      Delete
    3. Yes, unfortunately it doesn't solve the switch problem, it just gives you modulation on the repeats. But it can work with a different switch as you said. Glad it helped!

  11. Has anyone tried this with the taptation ICs for tap tempo? I just tried, but didn't get any delay signal, just dry...

    ReplyDelete
  12. I'm counting 36 cuts, is that right?

    ReplyDelete
  13. Sounds great! Could this be modded to keep delay trails in bypass?

  14. today i was clearing my unboxed boards, and troubleshoot this one.forget what i said 9 months ago. it was my mistake. missoldered the tone wire...now it works great, and it's gonna have a new aluminium home!!!cheers

    ReplyDelete
  15. has anyone added a mod board to this?

    i've built two different mod boards that are certainly making a modulated sound but seem to drastically affect the delay time, making it really short. any ideas?
