Wampler Faux Analog Echo

Today's layout is Brian's take on the PT2399-based delay. It's similar to many other PT delays, but is it's own beast. It can do anything from simple slapback delay to up to around 500 milliseconds of delay. I've laid it out for board mounted pots and it would be a snug fit, but i'll fit in a 1590B (especially if you use low profile jacks).

    aha! finally leviathan showed here!
    David, are you know how to add switch between tail and true bypass in this board?

    i build my own version with all board mounted pots and led (almost) like a dead copy!

    https://1.bp.blogspot.com/-B-M6Xw0BAOA/VwytmUWAqbI/AAAAAAAAAO4/VLMfOTbjXDwIFqh6KE5f32f_HR2a8M4WwCLcB/s1600/leviathan-perf.png

    i built with cheaply monolytic caps, sound not good as panasonic ECQ, so i not boxed it before ecq arrived. and want try your layout. Delay Junkies isn't crime, right? hehe

    Hail Sofa Car Effects!

    and lastly, we (me and my friend) want to build perf layout site. are you cool if we listed your site in exhange backlink?

      Here's where you'd put the tails switch

      Wait, how does the tails switch work? Sould i wire it like tails and when the switch is off its TBP?

    3. Effects LayoutsOctober 11, 2016 at 9:03 AM

      I think I messed up where the tails switch should go in the pic I posted earlier. It should be just to the left of the 1µF cap at the bottom of the board. If it were me, I'd forgo true bypass and just do the tails switch. The buffer design in this is very good and won't color your tone. But if you still want TB, something like this would work:

    Leviathan is not an exact copy of Faux Analog Echo. Brian did change some capacitor values and instead of repeat pot > resistor > capacitor order of connection he changed it to repeat pot > capacitor > resistor.

    I have built this version http://2.bp.blogspot.com/Bv4qmgsFmDs/VcpGO9h_GvI/AAAAAAAAFFY/5DPbXskXsvg/s1600/Wampler%2B-%2BFaux%2BAnalog%2BEcho%2BDelay%2Brev2.png based from the schematic posted here http://www.freestompboxes.org/viewtopic.php?f=7&t=22509&p=228891&hilit=faux+echo#p228891

    I've used cheap green mylar capacitors and ordinary ceramic capacitors for smaller values and I like it. For me it is better than my deep blue delay build with more expensive box type film capacitors (what a waste).

    I'll try building Brian's version (Leviathan) and test/check how it differs from my first build.

  6. Vivian FrancisJune 28, 2016 at 3:06 AM

    The pedal works. However, the repeats are very less (4 to 5 @ max) and when sustained notes are played the delay is drowned or suppressed. Is there a workaround to this. Again amazing blog. Thank you for your support.

      Same here. Level knob not going above 30% of the original signal and feedback never goes further than 4 audible repeats.

    2. AndrewSeptember 23, 2016 at 3:18 PM

      I thought that I did something wrong too... The echo seems very low and i can only get about 3 - 4 repeats and if you are still playing the repeats disappear in the mix... is there some way to raise the level of the repeats... I have also notice that if the pedal is used after a fuzz, all the tone of the fuzz is completely removed...

    3. UnknownOctober 27, 2016 at 10:12 PM

      I just finished this one, and the same stuff happens! There are like just 3-4 repeats, and the delay time doesn't seem to work at all...

      This fixed the low repeats issue and now it self-oscillates nicely. Thanks julungas!

      (Increase the 12k resistor that goes to pin 15 of the PT2399 to 47k)

      I have to use 100k resistor...smaller values didn't do the difference.

      Before it didn't a good sound quality, volume and repeats very low.

      Is that 12k resistor right in the layout?

      I did add a mod board Alex suggested for the Leviathan over here:
      http://tagboardeffects.blogspot.tw/2016/02/madbean-leviathan-wampler-faux-analog.html

      It is this board:
      "Also, this Mod Daughterboard from Mark might work:"
      http://tagboardeffects.blogspot.fr/2014/04/grind-customs-fx-deprofundis-delay.html

      It works but seems to need some tweaking. As long as modulation switch is off the Delay works exactly like if no mod circuit was connected. As soon as you turn modulation on delay time gets a little out of control. Seems to have to do with the fact that modulation only works upwards, i.e. modulation can only shorten delay time. Sounds great though. I might try the other circuit Alex suggested later:

    2. AnonymousJanuary 25, 2017 at 12:58 AM

      This might actually be how the circuit works. It turns the delay into a chorus-like effect and not plain delay time modulation (what I was assuming)

      I swapped it with this circuit and it works and sounds great, exactly the way I wanted

    Another question, where do I find the components (RC?) for the high pass filtering of the feedback if any? I'd like to add a switch that changes the high pass cutoff for more flexibility. Thanks in advance

      It's fine to combine caps, but you'll need to run them in parallel, not in series.

    Hi! Will this effect and "Wampler Faux Spring Reverb" work with line level signal? I'm building a synthesizer, and would like to add this board to the synth.
    If not, maybe there is a way to swap some parts to make it work with line level signal?

    Really interested in trying this one out but I'm just getting my head around the unusual component values. Pretty new hear so wondering about exchanging them with near valued parts. For instance -

    470k instead of 511k
    10k instead of 12k
    20k instead of 22k

    That'll work, right?

    Thanks for looking in.
