Verify it.

Here you go, bigger pads! So still unverified, but it won't be long...

If you make sure that the schematic you have drawn is correct (by comparing with the original and using the ERC), Eagle does that for you if you use the DRC. That's what it's for.

Checked by DRC, made a few little changes.

Still not verified ofcourse.

Hello
some News for this??
Greets Thilo

It's still unverified, but here's the latest version of my PCB-design. The only jumper left is on a pot (bias). I corrected some extreme angles in the traces and gave some of the traces a bit more space.

Etching now, hope to verify it within a few days (missing some of the components)

Ok, at this point I've got a low gain output with a volume drop. All the pots work like they should, the LED is working correctly, the bypass signal is ok. I swapped a few components for other values (like 10nF instead of 6n8, 91pF instead of 100pF) because I didn't have them, but I don't think that could be the problem. Could it be the IC? I used a 4069.

Any tips?

This is one hell of a confirmed build!


I did make some small improvements in the PCB design, so here is my latest, VERIFIED version:


Ready for transfer
Layout

And my design..

Please post the parts list. thanks

Please read the whole topic. Thanks

great job guys

I wish we make the board smaller that it would fit to a small 1290NS enclosure!!!

Btw, tnx alot!!!! weeeeeeeeeeee

was the volume drop resolved?

I can post eagle files on request, I've got some sound samples here! It's clean, clone, original.

No volume problems at all, works like a charm. Here's my build, next to an original:



*edit* just so you know, all of the samples were recorded using a fender strat, into a hotrod deluxe.

I finished making my own smaller layout. It should fit in a Zvex style enclosure. Will post the files here when it's verified.

Well, is the layout you posted just before my post the same? Is that the functional one? If so, no need for the Eagle files as far as I'm concerned.

Yes, it's the same verified functional pcb.

Greetings! I badly speak in English, therefore I am sorry.
It seemed to me that sound examples under these references:

And

http://www.gitaar.net/forum/index.php/f... eeza_3.mp3

The identical. I am mistaken?

You are right, the last one should be this:
