Destiny Behemoth

It's done! It was a long journey to get this one finished. But hey, who am I to stop destiny?

Shout out to @jjjimi84 for taking the time to dig up one his last pairs of PCBs for this. And the rest of the community for the collaboration that made this possible.

I didn't want to drill this one, so I made a tayda drill template for it. I had no issues with the drill pattern.


I did run into some hiccups trying to make the outside look acceptable. I scuffed up the face of the enclosure while trying something dumb. Since it felt ruined, I made it a candidate for my first epoxy resin pour. It rained pretty hard that day and the humidity made the resin cloudy, which also sucked. I decided to try and fix it with a 2nd layer. I cranked the space heater the first day and it came out looking much better.

I knew from the docs that the legs on the 9mm pots are just barely long enough with the belton brick attached. What I didn't think about was how much thicker the enclosure would be after two resin pours. Fortunately, I was able to carve the holes into a cone shape so I could get the nut to catch the threads. Just barely worked.

Biasing it was a breeze. I just matched the voltage readings to the suggested values in the docs. It took like 30 seconds.

To my amazement, everything worked on the first try. It was way cooler than I imagined it being. I was jamming at night in the living room, family fast asleep. Awesome.

I went to test the aux in, and then I realized I had been using my headphones on the aux in! Whoops- I had the headphone and aux jacks flipped. I swapped those around this morning, and that is working nicely too.

I feel like I'm going to get a lot of use out of this.

That looks killer. I’m too busy building to use anything, man!
Thanks!

Also, I forgot to mention, I changed a few values in the amp sim. I did what @Chuck D. Bones describes in this post:

 
I never noticed the bright/dark issue but I'm feeding it with a Tele...
looks great in blue. got me chuckling using the chickenhead for the most important knob;);)

I went middle of the road and arbitrarily picked 12nf for C16. Most of my guitars are darker than a tele.

And thanks! I had a big aluminum knob for the headphone vol at first, but I didn’t like the contrast with the other knobs. So I swapped it with a chickenhead off another pedal.
 
Great build and extra points for sharing the drill template 🙏. I've been putting off my second behemoth build (first was a gift) because I'm dreading doing all that drilling again 😂

Thanks! I don’t have a drill press, just a hand drill. With that many holes… making the tayda drill template was time well spent.

Offboard wiring often feels like a chore to me. I just finished my first build since this Behemoth, a typical PPCB 125B build. I really enjoyed how few wires I needed!
 
Without a doubt, the drilling and off board wiring on this thing is a pain in the ass. Maybe in the next revision there would be a way to minimize that with a separate i/o board, gonna have to talk to the boss man on that one.
