Sekova Big Muff Model 2015
This is a rare Japanese Big Muff clone made by Shin Ei. It is a clone of a triangle Big Muff, however it has some substantial differences to the triangle Muff layout we have here on the site. The 47n caps in the clipping stages here vs the 1uf caps in the clipping stages … Read more
NN Classic Fuzz
Happy #FuzzFriday everybody! Here’s a circuit I found while browsing around the Free Information Society that’s ripe for modification–the NN Classic Fuzz. I think I laid this out while I was on paternity leave a while back, but I just now got around to finalizing the layout. Anyway, I can’t find any info on the … Read more
Seamoon Funk Machine
The Funk Machine is a filter effect that can be used on either bass or guitar (or synth, Rhodes, harmonica, etc). It’s also like an auto wah, given that the wah effect is controlled by the string attack of the player. Original units used 2, LM741 chips, but I’ve laid it out for an LM1458 … Read more

Run Off Groove 3 Legged Dog
Got a bunch of CD4049UBE chips left over from building Red Llamas? Here’s something else you can do with them. You might need to play with the the value of the 8.2k resistor going to the drain of the J201 to make sure you’re getting to around 4.5v there. Also if you encounter squealing or … Read more
Red Fuzz
For #fuzzfriday, here’s the Red Fuzz, designed by Robin Tomtlund. It’s made up of 2 stages: the first is based around a single op amp with LEDs is the feedback loop creating clipping. The second is a simple FET-based boost/buffer. Much like a RAT, but with different clipping. The schematic and some sound samples can … Read more
