I'm building up the Dragonbeard Jr.  I have one 308 chip that I'm 100% about and another that I'm ~70% about.  I was wondering if either IC1 or IC2 would be considered more important to the sound of the pedal?  I.e. where should I put the 100% 308?

I'd go with IC 1. Looks like it will set the general tone. IC 2 is a dual Opamp and IC 1 is a single. Don't get them mixed up or it won't work and will mostly likely render your dual opamp null and void.

Woohoo!!

The charge pump is just to raise the voltages. I built one without a charge pump and then powered it with 9 and with 18. The only difference there was is when the breakup started.

There is a difference in clipping diodes, that for sure. I like to audition GEs to see what I like.

EffectsLayouts / storyboardist once had a project based on the bare bones klone project on FSB forum (skeklone) that omits the charge pump entirely in favor of using a higher quality set of dual op-amps (or a quad in the case of the skeleklone). Essentially, like jimi said, the charge pump is to keep the TL072s from distorting "improperly".

From the skeleklone 2 build doc:

based on the Bare Bone Klone concept put forth by FSB member earthtonesaudio. The idea being that the charge pump in the Klon is unnecessary, as the only reason it's there is to keep the 2nd opamp from clipping. However, since clipping diodes are in the signal path before signal reaches that opamp, and the fact that the 2nd opamp in a Klon can clip even with a charge pump, the presence of the charge pump isn't really needed. Especially if you use op‐amps that sound better when distorted.

And the clipping diodes make the most difference. Taste is subjective, and this horse has been beaten to death ...again and again. So Jimi is 100% right: experiment with what you like the best. I played myself, not knowing some of the diodes I had were not genuine 1N270s, and I actually ended up liking them the best.

Check out the build doc for the rev 3 Sunking for some recommendations:

...1n34a, 1n270, 1n60, BAT41 and 1n914. It's a good idea to socket these two and experiment to find your favorites. My personal favorite is BAT41.

I think I tricked myself with some unlabeled, weirdo 1N914s. To add my opinion to the pile, the 1N60P is good, also. I personally hate the sound of the 1N34A. Soviet era D9E is nice.

Yep, I made PCBs based on that layout. I don't o ow if I have any still laying around or not.

Got pics, an audio probe and voltages?

Very cool!

Killer. The I put pot sounds like a great idea. Where does it sit within the circuit?

Is this like September September or Madbean September-ish?

Okay, we're on beantime now. Still working on project docs. It's a haul but we'll see how far I can get over the next few days.

🤣🤣🤣 it's all good man, do your thang!

Seems like they chose the perfect time to close shop. Shipping and parts sourcing is about to become an absolute nightmare soon.

They never fully recovered from the hell that was 2020.

Seems like this happened one year right around Christmas. I was working retail then, that was not fun for a guy in commission.

Edit: yep 2002.

Also, the Tone Virus is listed twice.

Haha, no Sept actual time. Believe it or not I've stuck to my release schedule the last 2-3 months.

I'll delete the extra entry, thanks Jimi. Also a Degenerator is coming your way. I did not forget.

Yeah, but it's fun to give you the business. 🤣 the octave multiplexer in a 125b is something g I need to build, too. 😜

I too got my start with a confidence booster and an opticomp. I was just looking for a compressor not a hobby.
