Title: Mammoth (Madbean's Sabretooth) & Black Russian Big Muff
Post by: njkke on June 25, 2013, 09:12:21 PM
Mammoth build using the Madbean's Sabretooth etchable pcb
Really nice sound fuzz, tested both with guitar and bass

Trinity Feedbacker build using my personal layout (here's the thread: http://www.madbeanpedals.com/forum/index.php?topic=8392.0 )
I've found that the Tone pot wiring is inverted (1, 2, 3 in place of 3, 2, 1...)
I've jumpered the 39k resistor and used a 10K B pot for the Mids... it seems much more usable!

Man, those are beautiful inside and out!

Big Muff with only two trannies or am I going blind?

Nah, I'm pretty sure there's four... but the low contrast makes it pretty hard to see 2-3 of them. 
Tight layout, too.

Also, those both look fantastic.  Well done.

I was thinking the same thing.. I do not see them either.. I wonder...

I really like the graphics on these. Great job.

Yeah, a bit of zooming in and squinting shows them, the black transistor cases just don't show up well against capacitor shadows and naturally dark PCB tracks.

4 transistors as usual!  ;D
I've drawn this pcb layout to fit easily inside a 1590A (leaving space for the jacks too)...
so in a 125A there's plenty of room!
You can find my etchable layout in the link, if you wanna build a little (really little) monster... I suggest you to do the Feedback mod... it's crazy but really playable!
