Hello, My name is Jubal81 and I'm a dirt junkie. Built tons and I still had 5 on the floor at my amp. The idea behind the Brazen Bull was to take my favorites and get them all (well, not all, but a good few) in a 125B with just four knobs and a switch. I used headers and two PCB stacked together to get it all to fit, so lots of careful measuring and calculating.


There are four settings:
JFET boost
JFET Mu-amp overdrive
CD4049UBE distortion
Muff variant


These all go through a James tone stack. What you see here is the first prototype. There are a few things I want to fine tune and I've been back at the breadboard all week - 3 hours today and I ended up just changing one component. Maybe I'll be done before my beard turns gray.


The box is etched and then - gulp - electroplated with copper, rubbed with shoe polish and clear coated. Yes, it looks cool as hell, but I'll never do it again. I ruined two other enclosures, my favorite pants and spent about 8-10 hours just babying that thing in the copper bath. I wanted to get that 'excavated from a Greek island' look and I'm pretty happy with it.

Eh, I was waiting for sound clips, but that's gonna be a while. Glad you kicked my arse into getting this up.

Sick on so many levels! From the enclosure to the stacked PCBs to switch mounted relay pcb... this is just beautiful!

Thats a beauty in many aspects.

That is some next level stuff right there! I love it.. Well the pants are already ruined, so keep wearing them and do another enclosure.

Every time I reach for the bar, you guys raise it beyond belief. This is truly art.  Incredible. Fantastic job.

Don't you ever think of how the lesser talented builders feel?

Absolutely incredibly fantastic!

A deaf-blind would stare at one of these! ;D

Agreed with everyone else, it's definitely raising the bar. Far, far more impressive than "just another" clean wiring job (although I hate to sound dismissive like that.)

Any problems with crosstalk or noise?

Cool as hell. I love the copper patine,  and the circuit idea is awesome. I want at least one if you ever do a run of those.
