Andy 40's Madbean Snarkdoodle (Overdrive Pedal)

[Andy40]

Hey Guys.

I am a novice pedal builder but have a burning desire to demystify the ever elusive guitar pedal.

I have build a couple of basic boost and fizz pedals (I'll share when i have time), and now its time to up the stakes.

This weekend I'm attempting to start my take on the Madbean Snarkdoodle (Overdrive Pedal). apparently its based on the Way Huge Red Llama.

No, i am not ordering the PCB or any of the parts as a kit. I'm pointing this out of the ballpark and attempting to etch my own board and source all of the parts from my local Jaycar supplier.

The Build of Materials, Schematics and PCB layout can be easily downloaded from Madbeanpedals.com




Stay tuned kids

Thumbs up!

Wow, cool project, truly hand built

Awesome...Madbean has lots of other pedal designs on his website, he used to be a member of another forum that I used to frequent a few years ago, he's quite knowledgeable, I've built a pedal called the Grunt Box (basically a Big Muff) and it sounded pretty good, I think I still have the PCB somewhere amongst all my bits and pieces.

Amazing project Andy, can't wait to hear how she sounds.

cheers,

I've been seriously thinking of doing a DIY 4-Knob Tube Driver pedal build, I've built one in the past but it was a bit of a pain to cram all the circuitry into the small diecast box I used, so this time round I'm going to use a bigger diecast box same like the one I used for the Doctor Overdrive pedal, but I'll need to wait till I can buy all the parts for it though.

Might see if I can document the build-process with a write-up and some pics.

Etching

So printed the PCB layout onto magazine paper (found a use for 50million wife magazines!). I just had to tape paper on the top and sides so that it would go through the printer.


Then using the wife's iron (ha ha chauvanist) I transferred the image onto copper electroplate. Then soaked and removed the magazine paper.....it came out a bit dodgy, so i had to fix it with marker.



Then, ammonium Persulfated off the copper and voila

Nice work Andy! You're providing a template for the rest of us to do this properly. Great work - keep the details coming!

cheers,
Gav.

Hey Gav,

Thanks good to see you back on the forum mate.

Cleaned with Epoxy Thinner (its just brutal trying to clean with turps) and drilled.
