After building a couple Death By Reverb pcbs from PCBMania and being disappointed with a strong muffled/super dark tone on both, I stumbled across the Space Is Fun by Moonn Electronics. Not only does this pcb just nail the RM, it’s got a couple mods to choose from as well. One is a dry kill...

Got it, that makes sense. Thanks for the heads up!

The ones at Mouser are the ones I purchased before. They’re typically 115-125 hfe, as opposed to those FSC’s from Aion in the 80’s. They sound fine with the Carbon, but the others sound noticeably better. Less high end, tinny fuzz with the lower hfe ones. I’ll have to try the Carbon with two...

Stumbled across these and thought they’d be great for the Carbon Fuzz and other circuits that require low hfe silicon BJT’s. Just got some in and they all seem to be in the low to mid 80 hfe. For whatever reason, description on below link says 2n3904. Once you click on it, you’ll see they’re...

Thank you for the in depth response. I’ll check out Inkscape and see what I can come up with. That’s exactly what I was looking for, thank you!!

Yes, that’s exactly it. I figured I’d measure the controls on the pcbs and transfer to some sort of program that can save/print out templates. At the end of the day, I’d like to be able to have a result similar (if not more crudely similar) to the drill templates on the PedalPCB build docs. I...

Hello All, Hope the PedalPCB family is doing well. I recently came across some pcbs that don’t offer drill templates (Moone Electronics) and thought, rather than to draw/measure free hand, there’s got to be software (or something) available to do just that. I’m not great with computers...

Yeah, it’s more than likely a Foxx Tone Machine. Great circuit with a ton of sustain, if using trannies in the 400 hfe range. The earliest used 2n3565’s in the 200’s and were lower gain, not nearly as popular though. AionFX has the Vulcan with a three way toggle for the octave (instead of the...

Very interesting. I always preferred the ol’ scrape off the color codes and paint your own to match preferred resistance 🤪

The magnificent Chuck made mention of transistor needs in the Propolis, in an unrelated post. Helped me tremendously with that circuit. I’d go a bit further and read the thread as well. Also, if you haven’t yet, tons of great info in the Boneyard. :) 2. Differential-transistor octave...

Looks and sounds amazing! I actually built a couple of these (side by side) and was very underwhelmed with the final product on both. I tried both of the recommend resistors for R9, but just ended shelving them because I thought something was wrong with the trace. Yours sounded great! Makes...

Just finished one of two last night. Used an MP38 (88 hfe with very low leakage) and two BC108b’s (319/322). Biased MP38 to 4.5v and it sounds fantastic! Also, used a 15k trimpot (just in case) but I’m not sure it’s needed as it seemed that 10k would work no problem. Gonna audition a few...

Ended up biasing to 4.5v, I think that’s it because it sounds exactly like the demos -in case anyone else is wondering. Fantastic circuit!! Also, used two BC108b’s (319/322).

Is the MP38 supposed to be biased at 4.5v? Thanks!!

That is badass man!

Yeah, just checked yours out, looks fantastic and I love the enclosure you have for it! Do they have those at smallbear or something? Yeah man, I really like this one. Cleans up wonderfully too.

First of all, this is just amazing. Fell in love with this fuzz mere moments after first activating the pedal. Then I hit the second footswitch…. I’m done folks. I’m not a fuzz aficionado by any means, but this is probably my favorite so far (I keep saying that, but it’s true, I swear!). Not...

I’ve built a handful of these (cause they’re awesome) and on the last builds I could’ve sworn each of the three foot switches (Boost, Octave and Distortion) could be activated independently from one another and not like the EQD version where the Distortion had to be activated for Boost and...

Oh my lord. I actually saw this the other day and completely forgot. Also, I typed in Double Tap and Zap Machine in search and didn’t even see it! I’m a dunce. Thanks for taking the time to point me in the right direction!! Hope you’re having a nice weekend!!

I don’t suppose anyone has built this yet, or if Robert has a diagram for the footswitches on this one? Much appreciated!
