What did you select for volume control?
Tbh those artefacts are only there when not playing, and who expects a big muff to be quiet lol?

Fair enough. It just feels louder than others I've built, but might be due to the volume pot.

I'll poke around and swap it if it's the base 10k. Nope just rechecked my board post, and I used a linear because tradition.

Logarithmic? On an output volume? Who would've thought‽ I was building it to just see if it worked first 😂 but I might could have rechecked.

Verified my board tonight. Am experiencing the 'max sustain artefacts' LaceSensor mentioned over on PPCB, but there's enough to go around without diming it.

This thing is ...gutsy. Just pushes and pushes. I want to play a bit with components and values and see what mayhem I can get up to.

Hell yes ! Happy 2026 in advance everyone!

Lucky duck, you get to experience it before the rest of us  

Amen

Just a post to wish the Great Bean a merry Christmas, and all the rest of it. And I suppose the rest of you all, too  

It's been an interesting year for me personally, but I hope you're all doing well and keeping the spirit alive. 

All hail the Bean !

I placed a JLC order the other day and stupidly forgot to order even just 5 of my Muff2 layout. Sheesh.

I'll hook you up: power-IO, main, relay. Although I stuck with the slow boat, so it'll be a minute.


Although, it is val, so maybe too advanced

Thank you sir.

No problem!

I love it! Upload it, if you have time, please.

enjoy!

This is mapped to Bean's Standard Series 1590B, with control text spacing for 13mm and 19mm knobs. But feel free to give it a check.

edit: I should mention that it doesn't have any drill markers or labels for any potential tone bypass controls

Having some fun.

This one's gonna be laser etched, with the soot in place and sealed for the black. I'll upload the art of anyone wants it.

Brian, do you charge the layer colors to get them more pleasantly dark?

Yes, I have the most used layers set to custom colors to make everything easy on my eyes. I can share the settings if you want.

That would be great! Thanks.

Now if only the rest of the UI had a dark mode. 

Is it really different enough from the regular opamp muff to justify a new release?

"Yes!"

using my weird IO with top mount jacks and relay bypass ...and 1/8W resistors

Edit: fart. Didn't realize how similar it is to Bean's. Just came together that way.

This is seriously cool! Well done, both of you. I feel like garbage, so I sat laid down in bed and started adapting the mayonnaise fuzz mods/controls to the deuce. Won't breadboard them until I can sit properly, but there's a good chance at least one of the switches is placed wrong, as well as values needing tweaked, but it's the first bit of creative juice I've gotten in a while.

Seriously.

Great bit of history there! But man, what can't we trace back to Jack? Thanks, Brian.

I've been looking around at the various MOSFET based circuits out there, mainly from "What can I build?", and came across some things, all probably old news and deep lore™

I ducked out of DIY in 2012/3 and came back about a decade later, for reference. I found a couple of posts here, but wondered if anyone can share light on who made the MOSFET boost first, because the circuits are looking rather similar. Obviously, only a few components can constitute a big difference, and maybe I'm nuts.



I was looking at the Firecracker, Landgraff Clean Boost, and z*ex SHO, and wondered if one came before the other. I tried backtracing the Firecracker from mirosol's tagboard, before finding what appears to be the original schematic, with a "this is for DIY only" disclaimer. I'm out of it enough not to know when John debuted his boost. And I only know that, like many others, if you use the brand or circuit name on a Reverb ad, you get a takedown from the ghost of Randy Savage.

Firecracker has a different biasing method, from what I see, but some of the bits look very similar.
