Is there a DIY "Nano Big Muff Pi"?

Title really says it all...  Nano Big Muff Pi -  Noobie wondering if such a project exists.  Thank You All.

Just pick a layout/model you fancy, order the components in SMD and build it.  :icon_biggrin: However EH are known for components changes in their Big Muff builds and I am afraid the Nano is not that well documented, at the time being.

This will get you there:

Same size enclosure, same knob layout, and you can build any BMP variant you want with it. Pretty good newbie project compared to some other circuits.

If you're trying to save money, I doubt you could do it for less than the cost of a real Nano - but if you're doing it for the experience and the thrill of having something customized, you're in the right spot!

My smd layout is pretty tiny - 5.25cm by 2.25cm. If you use board mounted pots it sits quite happily vertically in an enclosure.



You need the .diy file to get the component values really as it's so packed in - and also for the solder mask, hopefully this link will work:

I've built a couple of these so it's verified by me.

Just realised that I made a later revised version to use smd transistors as well - this is the version I have actually used and verified. The layout pic is a bit more user-friendly as well.

if just for 1590A-ish Big Muff Pi
the layout below has designed to fit in 1590A with 9mm onboard pots, led onboard, and BC550 pinout
can build with big caps (4 hole) too, for greenies fans  :icon_mrgreen:

easy convert to perf, 13x21 , just one jumper (R6x) or you can eliminate that with looong R6  :icon_twisted:

Justinfun : awesome! like your style!

I have a one-knob Big Muff using 0805 resistors/caps and SOT-23 semiconductors.

The BMP will fit on perfboard with through-hole components in a 1590A. A 1590B is hardly unusual.

Madbean's Mudbunny is a pretty much flawless layout of the circuit designed for a 1590B. http://www.madbeanpedals.com/projects/

I've built the fuzz dog pedal part BMP circuit in 1590B. Whilst I have one 1590A pedal, I don't plan on building anymore - they're aren't stable enough when stomped. They easily topple sideways, I don't really understand the nano craze.
