Parasit Studio - Into The Unknown

Fredrik (Freppo) from Parasit Studio asked me to draw a vero layout for his latest creation:
Into the Unknown Guitar Synthesizer Deluxe, the big brother of his 0415 Guitar Synth.
If you want more infos on this great pedal or want to buy one of Fredrik's tidy PCBs you can check his website: www.parasitstudio.se



Here is a slightly modified version to stop ticking in bypass mode.
Removed the link between pins 8 & 11 of CD4069 in the top right corner and changed the LFO switch to DPDT On-Off-On.
Connected pin 8 to the new switch lugs 4 & 6 and pin 11 to lug 5.
Thanks to Michael Oriente for his suggested mod!

  2. Wow! Freppo does it again!

    The video sounded really cool. Kinda like a PLL at times, kinda like a TGD at times, but ultimately unlike anything I've ever heard before. The theremin like sound was a fun surprise!

    Thanks for this Freppo and Alex! This looks like endless fun

  5. Hey folks,
    I hope you will have fun with this one! :)
    Among my own creations, this is my personal favourite.

    I'll try to stop by now and then for support if anyone has any questions.
    Cheers / Fredrik

  8. thanks Fredrik! that's a great box! loved it.
    i just have to get some 4015 ics and turn my iron on!

    and Alex..your layout is a beauty mate!
    all pots and switches wires next to each other! how you always do it?!
    great job!

  12. I have to put out some orders prior to building this but would encourage anyone to charge full steam ahead without question. I have built nearly all of Fredrik's original designs. He is thorough and a genius when it comes to these fantastic synthy circuits. I just wanted to show my support to a guy who gives generously to the DIY community. Thanks Fredrik

  15. I have a couple of newbie qustions..What the difference between yellow and red caps and which enclosure shall I use, for more comfortable PCB placing?
    Thank you!

    1. By the looks of the vid it was built into a 1590BB. As for the caps, red or orange caps on vero layouts are usually used for ceramics in the pf range. But sometimes when the two legs are spaced next to each other they're also used for bigger value caps. That doesn't mean you have to use ceramics there, it's just that the image for a box cap cannot be made that small to only fit two rows.

      Best rule of thumb for caps is: for everything below 1nf use ceramics, for everything from 1uf upwards use electrolytics or tantalum, (although you can use non-electrolytics for 1uf as well, it's probably even better most of the time). For anything inbetween those two valaues use either box caps, polyester caps, greenies, multi-layer ceramics, whatever of those you prefer. It will not matter much soundwise, although it will matter size wise.

    2. Pretty sure that the demo has a 1590BB for enclosure,but I'm quite certain that it's a PCB inside. I don't think the vero would fit in that.I could be wrong on all these points though.

      Delete
    3. The video would definitely have the store bought PCB inside. I reckon you could fit this into a BB. Check this link for BB size - https://nonameboxmods.com/hect/hammond.html

      Remember vero is generally 0.1" spaced.

  16. holy shit guys! i've just verified that laser gun!
    what a fantastic circuit man!
    Fredrik thank you so much for this one.
    there are not many effects that i've build and felt that "thing"...you know..when you smile like a kid, playing with your new toy...

    fired up right away.the sounds that this thing is screaming out are fucking unbelievable!and no way to explain them of course...!!!

    i didn't have an on-off-on switch for the LFO so i tested that using alligator clips.
    tones of volume there, but it's 3:30 in the morning here so i can't test it at high level.
    i'll come back tomorrow with the ics working voltages.
    good night and thanks again Fredrik and Alex.
    cheers

  17. Just got this working on the breadboard.... Insane. This is now my official holiday project, hoping to be to cram this vero into a 1590N1.

  18. Big thanks to Frederik and Alex. Built today and WOW! This is such a fun pedal, so many crazy sounds. I do get quite a noticable tick though, but maybe that tick isn't avoidable.

    1. I'm glad you like it! :)

      If helps to turn up the gate and turn to down rate when not using the modulation/LFO to minimize the ticking.

      Unfortunatley alittle bit och ticking is unavoidable. I had noticable ticking on the breadboard, but with the PCB build the ticking is very faint, hardly noticable. I guess that's one of the things that sucks about vero: no proper ground plane and longer wiring, so circuits with LFO's are much more prone to ticking compared to PCB.

      Delete
  19. Is that ticking a showstopper? Or happens only at some extreme settings? Any demos? Still worth a build?

    ReplyDelete
  20. I can't hear any ticking on the demo, unless the gate is dialled so as to give self oscillation

    ReplyDelete
    Replies
    1. That's because the ticking is very faint on the PCB build. Don't know about the vero though, it's just more prone to ticking in general.

  21. Is it 37 links, or actually 36. Feel like I'm going mental.

    1. I just had to go over the links again, I'm counting 38!

    2. Yes. I have counted them again now several times, and I count 38 aswell :P

  22. Updated Links and video. :)

  23. The craziest pedal I've ever built. So many incredible sounds... I have absolutely no idea how all the knobs work (specifically, the track, warp and gate knobs are very interactive) but I spent hours just trying different settings. So much fun.

    There is a background tick but gate knob maxed solves it. Tracking depends a little on dynamics and pickups settings.

  24. hi,
    soo fun, thank you for this big layout. Is there an equivalent for 4015 IC?

    ReplyDelete

    1. Hi! There is no 4015 equivalent

      Delete
    2. I found 4015 at Futurlec.com
      Hope this helps you out

  25. Stereo outputs would be good in this pedal. Anybody knows how to do it?

    ReplyDelete
  26. I finally received my CD4015's today, however...

    All the controls seems to work, but the ticking is pretty loud. Sounds like a metronome when not playing, even with the gate maxed. In fact the gate doesn't affect the ticking at all.

    I used shielded wire for the input and output, pot wires are short and also tried to isolate the supply to the top right 4069.

    I'll post a recording before I start digging in, just in case this is the same tick mentioned above. I doubt it though, because it's pretty annoying.

    There must be something wrong, just not sure where to begin.

    1. Here is a video clip of the ticking. The ticking occurs in all modes, all settings. It can be heard while playing too.

    2. Need a favor, before I throw in the towel on this one, would someone who also built this let me know if your getting the same ticking I have in this updated video.

      I moved some components around which somehow improved the volume of the ticking, no longer sounds like a metronome. I can't really hear the ticking anymore while playing, but as soon as I stop there it is.

      Thanks!

    3. hi mate! mine works like yours i think...i can't really hear the ticking clearly in that youtube video, but i can live with mine which also ticks a bit just like yours i guess. anyway...i thing that with freppo's pcb, we wouldn't have that problem.

    1. I found a workaround to completely eliminate the ticking. By simply disabling the LFO.

      If you don't mind losing the LFO, I think the simplest way is to cut the link from the top right 4069 pins 8 to 11. I simulated this idea by lifting pin 11. No more ticking!!!

      But then the cool LFO effects are permanently lost. For some reason there is still some interaction with the LFO switch on, but nothing like the original LFO sounds.

      A better option would be to replace the SPDT on/off/on LFO switch with a DPDT on/off/on. Remove the link from pins 8 to 11 and run a wire from the pin 8 row to lugs 4 and 6 on the new switch. Then run a wire from pin 11 (where the jumper had been) to lug 5. Lugs 1,2 and 3 are wired as before.

      This way the LFO can still be enabled, along with the ticking (which isn't really noticeable until you stop playing). However, now when the LFO is turned off, the connection from pin 8 to 11 is also interrupted and the ticking is completely gone!

      Alex, I think it would be a good idea to update the layout by moving the 9v supply and diode to the 1st row and remove the cut at pin 11. And remove the link from pins 8 & 11 too. This way the modded DPDT switch can be wired from the edge of the board as usual.

      Verified by me.

      I posted the same info with pics here:

      Sorry but I've missed those previous comments.
      I've updated it.

    5. Thanks Alex.

      Please note, I'm not sure if this is the best, or safest way to disable the LFO. But I have done it similarly on both the vero and PCB without issue...so far. (Pins 8 & 11 on the vero, pins 9 & 10 on the PCB)

  28. "Bypass the ticking mod" on hold. (my sincerest apologies)

    I don't know what just happened, I finished up the graphics tonight, unboxed the PCB version to install the LEDs, and the ticking is worse than ever! No different than the vero version.

    In the modded LFO bypass mode, the LFO LED randomly lights, sometimes it does, sometimes it doesn't, but eventually the ticking returns in the bypass mode.

    At this point, my frustration level is at its peak, not sure if I've created a new issue, of if not having the LEDs installed masked the ticking.

    Going to have put this aside for a while.

    Again, my apologies. When I noted "verified by me", I hadn't yet installed the LEDS. Won't happen again.

    Mike
