I borrowed this from a friend. My only camera is my iphone so they're not the best but hopefully I can get some better shots with another friend's camera...

I'll try and get some better pictures up.jymaze wrote:Thanks for the pictures. Cannot be traced from that though.
The PCB design is really looking amateurish and the traces are so thin... I would be ashamed if I was the designer.

I'd be more ashamed by the poor soldering job . Look at the footswitch pins which scream for solder !jymaze wrote:The PCB design is really looking amateurish and the traces are so thin... I would be ashamed if I was the designer.
these guys are really a joke !

I don't know how to use Eagle. Thought others might like to see this

Ahh, gotcha. Sorry forMbas974 wrote:Do not MIS understood me.. i thank you too for the pics..
Just surprised me these guys and their boutique pedal....
So. I did my first LARGE trace on this - I've done smaller fuzzes before. So forgive my total noobisness. Attached is a hand drawing schematic -brace yourselves. Also a small doc with pot values and the ICs...

Information
Same for the pads for the switches and pots. The drill diameter is so large the solder is needed as a bridge to fill the gap between board and component. Solder is a rather poor choice for that function.jymaze wrote: The PCB design is really looking amateurish and the traces are so thin... I would be ashamed if I was the designer.
And as well, thanks for the photo's!

I see that. Here is a link to another schematic upload, this one was scammed at a higher dpi so I don't think I can attach it here (its 26MB).benweasel wrote:Great Work. I checked the scheme ,but upper part is missing.

I'm using Fritzing for the schematic - first attempt, so its not the best. Better than the drawing and I think I fixed any past errors.

updated the schematic again. I built this on my breadboard and then on perf and it works... The orange trace is just meant to show that the other trace it crosses is in fact a cross and not a connection: I'm using Fritzing and I don't know how to indicate connection passes/crosses. Noob.

by clever, do you mean lazy?

The Biyang AD-10 delay has the same features for $50, and up to 1 second of not too noisy echoes.

I think I built this for less than $50 (Thanks Tayda - though I needed to get the 2206 from Small Bear), and it sounds pretty sweet. That Biyang doesn't have the modulation, and the fuzz is actually pretty cool/useful feature. I agree I wouldn't pick up a ED2 but for a DIY build: its pretty nice. It is noisy though when you get around/pass the 600ms point.atreidesheir wrote:The Biyang AD-10 delay has the same features for $50, and up to 1 second of not too noisy echoes.
