Could it be that R11 is 47k ?
And there is really no additional 1M at the gate of T2 ?
BTW, the footswitch SW1 appears to be replaced in your unit. Originally it is a 2PDT swich, the same as SW-2.

again.. changed. While attempting to avoid these kind of remarks I do thank you for keeping me sharper.analogguru wrote: Could it be that R11 is 47k ?
Checked, checked and doublechecked since I already expected a (justified AG ) for that.analogguru wrote: And there is really no additional 1M at the gate of T2 ?
Nope. It's not there.
I don't have a reason to believe this to be the case while I do for SW2 where secondary soldering seems to be in place. If so, it's done by someone who does know his soldering skills very well.analogguru wrote: BTW, the footswitch SW1 appears to be replaced in your unit.

And for those who consider (some) of the above asskissing or whatever they want to call it, Too bad. I do consider AG one of the better teachers in critical focus on details and thank him for that.

No asskicking whatsoever to me, but I must admit that I have thought: how come can he (AG) compare/analyse a schem that fast?!Dirk_Hendrik wrote:And for those who consider (some) of the above asskissing or whatever they want to call it
But yes, AG's knowledge is amazing, and his sharing is so cool...
- Are you a mod or a rocker?
- Uh, no, I'm a mocker.

with a huge picture collection.
And this picture collection shows a 2PDT for S1 in all cases. BTW, I havent seen 4PST used in japanese boxes originally. They were common in european pedals like from Schaller.

And a good sight, not like mine challenged with colorblindness... It would take me a lot of zooming on the second picture to actually compute a resistor value...
I have to use a magnifier and a bright lamp to make difficult readings on the resistors...
Anyway, thanks to both of you for info and schematic about this unit...

Don´t bother, I couldn´t do this too from the second picture (alone). I used the picture below, but even with this I was not 100% sure about it. Therefore my question to Dirk.lolbou wrote:And a good sight, not like mine challenged with colorblindness...

I can sometime read them with a magnifier in good light.. otherwise i have to measure or get my son to tell me what it is..

i wonder-
would JFETs have to be picked for tolerance at the factory for this circuit? you would think that there would be a large amount of variation between boxes if they didn't do some kind of sorting.

Hi Dirk,
thanks for the schematic and the layout of the Double Fuzz.
But, I´m a little confused:
in the schematic the 2,2 electrolyt-cap on "out" (balance-pot) is with pos. to SK30 - in the layout (https://www.freestompboxes.org/viewtopic.php?f=13&t=6994) the cap is with neg. to the pot?
Is the schematic right?

Thanks for poining that out.
The layout is the correct one. The schem is wrong on that location.

How about R8? Is it 27k as in schemo, or 47k as in layout?

You are missing inductor for wah....rest should be easy......do you have pots and switches? box?
