I think this is supposed to resemble the Fulltone 69.

Looks right 2 me... Q1 hfe 84, Q2 hfe 115, C2 20uf thats the only info I can add...

Or...

Q1 hfe ~ 88, Q2 hfe ~ 123, C2 22uF!

Don't forget to adjust the trimpot for more-than-excellent sound!

Maybe you could buy one, reverse it and share on here if you want a 100% accurate copy, also maybe a bit more gratitude to those who've already tried to help might be good and help your cause

FFS grow up. If you want it that bad do some bloody work yourself. Here's a head start. Get tracing.

Now compare it with the deatails on this website

BTW, that took all of 10 minutes searching.

By the way, the LED in the GGG schem is backwards.

The 18k resistor in the Fulltone is for the LED.

.... and the output coupling cap is only 10n (instead of the 100n shown in the schematic). The rest is like in the four units I had for tracing.

BTW, the ß of the first transistor varies between 84 and 96 and the second between 105 and 128.

I built this a while ago, sounds great. I don't remember where it came from.

Note that the transistors need to be flipped 180 degrees from how they are shown on the layout.

really?

i built that one as the layout suggests and it works fine. i guess i'll try flipping them

The emitters should be toward the bottom of the board, away from -9V. The way it's drawn shows them to be pointing toward -9v. Check any FF schematic to compare.

Ok thanks for you answer

Input goes to bias pot, output is from volume pot, take the positive ground to somewhere on the bottom strip.

Hi,

do you think this layout is good for a Fuzz 69??

Thank's from France
