It seems that not all of the sixties fuzzes were verbatim tonebenders. There's not that much difference blueprintwise, but still noticeable difference. Some might want to clone this too...
Geiri modded his build a bit to get its sound closer to his preferences. Some of you might want to try these mods out as well. Word from Geiri and demo of his modded build:
I basically changed the 10nf cap by the input to a 100nf. The 10nf that goes to level 3 changed to a 47nf and I changed the 1.2nf to a 10nf. Very simple and for me, it improved the pedal a lot. the 2k pot was too big before the change and it would start to make noises but after changing the caps, it's fine. I recommend using a 2k pot if you're gonna do these changes. - When you max the gain, it's still quite bright and more like a distortion but if you switch to neck pickups, it goes a lot fuzzier so I kinda like it!
