Hetakusonic Videl (Roger Mayer Voodoo-1)

After finding about this fine bunch of components and spending some time in the boneyard I decided to try designing my own pcb. Armed with EasyEDA and the schematic from the Voodoo Woman thread I tried applying some guidelines I found on the forum while copying the familiar PedalPCB 3-knob layout lke a monkey. I angered the gods by converting it from double buffered output to single true bypass. Placing the components logically and connecting them is an interesting puzzle game. I wanted to emulate Robert's beautiful symmetric layouts while avoiding long connections and I came up with this abomination:

I must thank @Chuck D. Bones for the precious help he gave me by checking my work and giving me more precious tips. He also helped me address the issue of the the ball-desiccatingly low volume of the circuit by suggesting the 3rd stage he used on the Voodoo Woman. I added it on the 3PDT board and it was just perfect, even though I guess I didn't include a way to turn it off.

Oh well, it's just the first experiment and I'm sure I made many more mistakes. Like forgetting to set the spoke size for ground pads and obtaining spokes the size of Greenland. :rolleyes:

The pedal sounds lovely and borders on fuzz territory. There's a 3D quality to the dirt it provides. A hint of chorusy depth, as if the notes were shimmering. Maybe it's the voodoo it's made of, or the magic "no chinese bullshit" LM308H, or the fact that I'm drunk.
Anyway, I really love how it turned out and the fun I had while learning new skills. Now I can suck on a whole new level. Peace. 🖖
 
Really clean design and a nice first PCB layout. About the only "rule" that I can see is violated here is around orientation - the two plastic transistors on the main board have different orientations, as do some of the electrolytic caps.
 
Thanks a lot, I was a little overzealous in my search for the shortest paths. I think I understand the logic behind this "rule". I will try to keep the same orientation next time.
