Dirtbaby

Hi all, here's my successful Dirtbaby which apparently makes me a  'genius' lol, too much credit Madbean ;]

Anyway it went without a hitch apart from testing when at first I didn't realise I needed to hook up both sets of inputs/outputs, perhaps a note about that in the build report for us less gifted geniuses?



Even though this is really well designed too make the wiring easy, I can still make a pig's ear of it! I messed up the slam switch and had to redo it— too embarrassing to tell you what I did wrong 

Finished with Posca pen over flourescent red acrylic.



great sounding delay, thanks Brian.

Fantastic, really neat design.

Looks great!  I love what you did with the posca pen!

That came out looking great

Great build.

I've not heard of posca pens.  Did you do all the black by hand?

[darrenw6000]

Good build man. That green led have to be in the circuit to work then?

[29palms]

thanks guys! Yeah I did the black by hand, was difficult to keep a steady line, I should probably cut down on the coffee ;]

The green LED is there to stop the pt2399 clipping I think...

Wow!  That's an excellent job.

Pretty much! It's more or less pretending to be a zener diode. If the voltage stays under ~2.3V, the signal comes out of pin 7 and goes along its merry way to the rest of the circuit. If the voltage spikes OVER 2.3 though, it leaks through the LED to ground and prevents that nasty gravelly crackle of an overdriven '2399. Really clever trick really, and only costs 3 cents to implement (You can leave the LED out, won't change the rest of the circuit, but it solves one of the most common issues with the chip so why not?).

Really cool! How did you protect the Posca paint after?

[beneharris]

Dude, one time when I first started getting into playing, I actually sent in a pedal for repair work because I was putting the cables in the wrong jacks. Input in output, etc. Nothing you could possibly do is any more embarrassing than what everyone else has done.

That is a really cool build. Good job!
