Yeah, I see now that it wasn't an original unit pictures in the original post - it wasn't mentioned till later that it was a replacement pcb built by AG.

:lol: yeah, AG posted it himself.
however, on page one he mentioned twice that it's a clone he built. unfortunately somebody misquoted AG's first post, creating the impression that AG's clone is an original circuit board.

that thing in the enclosure is the original circuit. AG clearly stated, that it's easy to clone it and posted pictures of his own clone as an example.

Yeah, I just really don't bother to "question" when AG posts a picture. Usually he'll state any alterations to the circuit in the post, which wasn't done, so I assumed it to be original.

My mistake, but an easy one to make given the wording of the post. No big deal.

Can you show me please where is the case, the wiring, the pot, the jacks ?

THE PICTURE OF MY PCB IS ONLY TAKEN ON A BLUE BACKGROUND WHICH IS IN REALITY A FOLDER FOR PAPERS, THERE IS NOT EVEN A PIECE OF A CASE AND THERE IS NO "ORIGINAL BOX".

When you cannot recognize the difference between the original and the clone, buy some glasses and count the holes in the perfboard.

Evidently there WAS doubt. I'm FAR from stupid, and because of your posting history thought it unnecessary
to sit and "count holes" as you suggest. I simply thought that you had removed the board from the original unit. I'm sorry that you left some ambiguity, as evidenced by another posters comment -
jrod wrote:What are the pictures of that AG posted? Colorsound One-Knob Fuzz?
Seriously AG, you're getting all offended because I didn't bother to "question" your original post as an original unit, simply because in the past you've made it crystal clear what was not original. Seriously ? If anything you should be "flattered" that your past history leaves you "trusted", but instead you're here making a HUGE deal out of this. As I said in an earlier post -
My mistake, but an easy one to make given the wording of the post. No big deal.
Your "Thats very easy, as you can see here:" comment to me simply meant it was simple circuit and would be easy to clone, not that this WAS a clone - as I said, I misunderstood. You win. You're the best. You're never wrong . I'm the biggest idiot in the fucking world. Here's your box of Cheerios.

Another stupid fucking argument over absolutely nothing. Fucking ridiculous.

Maybe the cause are my poor english skills, but it really sucks that I have to waste my time for justifications, when IMHO I left no doubt about the matter.

And as I said, my interpretation of your post left doubt. I'm not gonna sit there and "count holes" to verify a circuit as you suggest, when your past history shows you to have been exceedingly clear about such things. That's why I didn't scrutinize the post further.

It's all good ...and a ridiculous thing to "argue" about. It's not just a waste of "your" time, but also "my time" to have to defend myself because of something that was "unclear" by my interpretation.

It's over, done with.

Amen +1

actually you can go from something like 47R up to 5k, to get a wide range of fuzz sounds, I like them all

Please forgive my ignorance, but, does the 82R/820R only affect the volume or would changing its value change the fuzz characteristic as well?

Thanks for your efforts, MoreCowbell, and glad to see you back here. I always enjoy your posts!

apart from volume increase, the values i experimented with:

at lower (82R) it sounds "grainy" and slightly gated.
at medium values like 1k~2k its more straight distortion,
higher around 3k and up goes into heavily gated, scattered, angry fuzz

Interesting! Thanks, cpm! I guess some experimentation is in order!

Why not add another pot in series w/ an 82R resistor?

To go from one extreme to the other and dial in a different tones? That does sound like a fun idea!

the 82R + anything from a 1k - 5k pot should work just fine.

I don't know specifically what they're doing in there. When you see the pics: http://www.macaris.co.uk/image_view.asp?img=140.jpg
You'll notice a bunch of extra stuff in there. There's diodes, more caps, another transistor, could be a jfet with protection diodes? Anyways you could try out the input buffer/splitter/blend section of the Scrambler instead and see how it goes. Its easy to breadboard.

built this pedal (finally) using an old behringer channel switcher as a base (judging by its habit of chewing drill bits im betting solid steel)

sounds veryyyy gated and out of control but is suprisingly melodic too. Works well with an overdrive after it to boost it a little
Im running mine in the effects loop of an NS-2 (switching it out for an MXR noise gate clone when i can) to get rid of the hiss

Would recommend to beginners for ease... just make sure you find a box that is more suitable!

anyone know if you can do a tonebender trick on this and replace one of the resistors with a pot to reduce hiss?

not quite sure how it works on tonebenders but blondegraemey on youtube has a video of it.

Hi there, I took the time to redraw EW layout, hope it doesn't bother you (hope all credits due are there...)
Here it is...
