I just got the same Problem a few days ago. I played my Pitch Shifting Delay and kicked the Rub-a-Dub and shhhhhhhhhhh. Horrible white Noise, increasing with the Pot turned up. It worked perfectly before.
After i pulled the DC Plug and put it back in, it was fine again until I turned on any Drive Pedal or something with a higher Output. Maybe the Circuit/Belton Brick is overdriven by higher signals?

Did anyone find a Solution?
I don´t use tantalum caps, just normal electrolytics, no Regulator from Tayda. But i will measure it tomorrow, if it gives 5V.

Absolutely stunning Build! Love it, so clean and tidy and the Outside is unbelivable awesome!

I like the simple Design of the Colorsound Overdriver.
How did you get the color on the decal be so visible?? When i tried to put an orange printed, transparent decal onto a black painted Enclosure...the letters on the decal vanish, because the black Background is to dominant. 

I´also a Lurker, named Fabian. At the moment i´m studying EE with Informationtechnic and Mediatechnic with topics like soundengineering, filming, cutting etc.
Building Effectpedals is my Hobby and i´m still stocking my bench and building my workshop, that´s why i have done only a few pedals till today, but i want to do a lot more in the future (got a lot of hundrets of GERms in my stock)

Hi,

I could not find any other Threads about this Method, so i hope it´s okay, when i´m opening a new one for this. Sorry, if my English is not that good, i´m from Germany, but i´m doin my best!

I just finished my Prototyping setup with Breadboard, Breakoutbox with Voltage Sag Pot and all that. Before i made the Breakout Box i got very much Noise from my Laptop, Lights etc. coming in the Signal Line, because the Jacks etc. were not shielded. Then i put all the Stuff in an Enclosure and the main Noise was gone, so that i could finally hear the effect and changes, that i do in the circuit. Before that i din´t even heard the fuzz Sound...it was coverd by Noise.

But there was one Problem left...Hum!! It was not a big issue, because i could now analyse and listen to the circuit effect/sound and could tweak. Then i used the Voltage Sag Pot, to try out, which effect it has on transistor starving. After a very small amount of turning the Pot...at i think 8,7 Volts, ALL the Hum was gone! And the circuit sounds still the same, so i am working now always with a little less Voltage, controlled with the Pot and my circuit is completely Noise free!

Insane!!! Building all of these will drive me Insane!  Thanks a looot!

One further Question. Do you think these ones are no fakes?

Okay thank you for the answer. I wrote them to give the diodes back. Thought these Asian Ebay Stuff would be kinda cheaper, but in result, when i order my parts at Musikding or UK-Electronic here in Germany, i get better Quality and really the parts, that i want and not some kind of Fake..and pay only a little bit more, maybe 10c or something, depending on type.
Hope those 1n914 are okay, because of the yellow band, but i saw the same type on some diode-type-list page on the internet, too.
The only parts i will still order in the future, are Resistors from SunElectronics...a whole lot of working ones for around 20€, within delivery costs.
And maybe some usual Transistor Types, like 2n3904 or 5088...can´t get em cheaper here in Europe, even if some of em are not working. But as i read, i will get my BC108Cs, BC107 and J201er ones better here in Germany from reliable Deliverers, than the not working, leaking and fake ones from Asia.

Thank you for your Help.

I ordered some 1n34a from an ebay Store, named Zeuselectronics. They showed a picture of the standart looking Glashousing germanium diode and described them as ge diode in the description, too.
Today i got the package and the look weird. They are very small, orange and the Ring is printed is white. The only mark, thats printed on is an "H". Did i got fake Diodes?
Heard from other cases with Tayda orders. From them i ordered 1n914 and 1n60p Diodes, they are orange/copper colored too and have a black, the 60p (like these http://image.cn.made-in-china.com/2f0j01cQtTpkfamESw/%25E8%2582%2596%25E7%2589%25B9%25E5%259F%25BA%25E4%25BA%258C%25E6%259E%2581%25E7%25AE%25A1%25EF%25BC%258D1N60,1N60P.jpg ), and the 914er a yellow ring (like these ones http://www.flickr.com/photos/goa2008/3771606953/ ) , hope these are okay.

How do i measure the diodes and how schould be the results? Is it just Voltage or Diode testing Option on my dmm??

My picture files are too large to upload, i post them tomorrow, but the 34a ones look similar to the quoted picture of the 914er.
