Noise Ensemble

Here's one insane fuzz/noise machine invented by Anchovie at the diystompboxes forum (original thread here). Have a look at my completed build here.

Hey man, your link to your build is 404.. I wanted to see your build of this. I read all 7 pages over at the diy site, and then built mine.. I ended up putting a pot in series with the 47k resistor so you can send the resistance sky high which cleans up the delays.. affectionately called the 'Juice' knob.. otherwise it's basically Anchovies circuit... I'm thinking about putting a cap across the input as one member said he did to trim down the initial treble which makes the sputter more of a crackle.. I had good results with rolling the tone knob off half way or so. Thanks again for this layout!

Hi Brett,
That for the heads up. Link updated. :)

It's a very fun circuit. I'm glad to hear that the layouts are being used. Cheers / Fredrik

What value worked best for the potentiometer in series with the 47k resistor?

I used a 500k. Just revisiting this build as I never boxed mine and was finally getting around to it. Momentary stop switch for the loop option between input and output. 22k for shambles, yeah it's fun. I never liked the capacitor mod much.

Hi

I built one of these pedals from your layout (Thanks, again!).

This pedal is so much fun, and a signature sound waiting for the right guitar player.

I added the loop switch but only get noticeable feedback at an impractical volume level.

From using a feedback looper I made (Beavis Audio), there seems to be a sweet spot from the feedback pot between no feedback and amp breaking.

Can you suggest an appropriate pot value that I can replace the 3.3m Resistor with. I don't have the electronics knowledge to work out if I need to be adding more resistance or less to get to the point where the feedback occurs.

Thank you, again


JC

Hi Joey,

The loop should not increase the volume if it's connected between the input and the volume pot lug 3 (insted of directly to the output). So you can try that. Lowering the feedback resistor value will increase the feedback and vice versa.

I hope that helps

Hi Fredrik,

Is there a way to get the circuit self-oscillate?
Thanks,
Regards

Marc

Hi Marc,

Yes, you can add a resistor between the input and the output for self oscillation/endless repeats. In my completed build I put a 3.3M resistor in series with a SPDT switch between the input and the output on the board (row 3 and 4 on the right side).

Like this: row 3 (input on the board) to the resistor, the other end of the resistor to SPDT pin 2. SPDT pin 3 to veroboard row 4 (output). I hope that makes sense.

You will probably want to experiment with the resistor value. Lower resistor values will increase the feedback.

Best regards
/ Fredrik

hey, i actually did not understand what to do with the 2nd and 3rd lugs of the shambles pot. do both of them go to 1xM point on the veroboard?

answer of this will help me with lots of other veroboard schematics as well, so a huge thanks in advance!

Hi there,

Yes. That's correct. Both lugs connects to the 1M point on the board. It's easiest to just put a small link between lugs 2 and 3, and one wire to the board from either solderlug. :)

Cheers

many thanks for the reply! i got excited to build this one once you replied, but when came home and checked the components, realized i only have one 47nf and don't have diodes other than 1n1418.. but i'll get them with the next ordering and build this sweetie.. thanks a lot again for your help:))

Happy New Year. I made noise ensemble with reference to your layout. We also installed two types of mod. I have a point to worry though it works although it is operating for the time being. Minimizing shambles pot (delay minimum)
Noise appears as if oscillating even with loop sw off. I do not know the cause as it does not appear in your sound sample. Basically I made the same as the layout, but do you understand the cause? shambles pot
Because I did not have 22k I am using 20k. Or there is something wrong with ground wiring?

Hi I also got the same porblem. I always got the feedback even if I switch off the auto-oscillate mod. Any help?

Hi !
By connecting the input and the output with a momentary switch the 'stutter' effect is really cool. Do you think we can get this with clean repeats, I mean no fuzzy sounds ?
Cheers!

I havent tried connecting the input to the output for self oscillation, but i did just built this and it definitely already self oscillates without a mod. Isnt it supposed to? If i dont play, there is noise. Isnt that oscillation? Im actually curious of a way to make the noise/oscillation/feedback quieter. It overpowers the guitar tone by lots on my buil. Any help would be much appreciated. Thanks!

That doesn't sound right... If I remember correctly (it's been a long time since I gave my build away) my build was totally quiet and very gated while not playing (without the self oscillation switch engaged) with only a single decaying delay unless the self oscillation was pressed, then the repeats gets into self oscillation. But it will probably depend on the PT2399 chip used, since they vary alot in response.

This is a great effect. Now I've built one, I'd love to learn more about how it works. Has anyone done a breakdown/analysis if the circuit? I tried looking on elecreosmash, which is my go to but sadly nothing there.
Particularly interested in how I could separate the fuzz, delay, etc out and have them on individual controls. Cheers

Hello...thanks for the cool site..hey do you have a schematic for the noise ensemble? i am not familiar with vero boards...thanks jim

I don't have the schematic i'm afraid. Maybe check the original thread that I linked to, or ask there?

Hi. Ive made a little Feedback/Repeats daughterboard for this if anyone needs it.

https://imgur.com/gallery/BvtzmTh

Its super duper easy and just goes straight between the input and output.
It works across the jacks but i had better results when adding an extra input/output wire to the board and vol 2. Its sensitive so might work better with an A or C pot.

Hi there! Thanks for posting this. I’m new to vero layouts like this, and i had a question about the ground on B10. Does that mean the ground lugs for the in, out and 9v all connect to b10?

hey im lost at the 22kb for shambles? its mentioned in other replies so you must mean it i know 22k is a common resistor value. just not a pot value. am i missing something?
