I thought I had read that it's the fuzz side of an Octavia pedal.

Up.. I'm going to buil it.
Please note that looking to the board I noticed different values for R11 and R13
Anyone know what is the capacitor on C7 ?
What are NPN Transistor Q1 & Q2 ?

R2 820k
R3 180k
R4 220K
R5 1K
R6 220K
R7 470E
R8 47k
R9 100E
R10 1K
R11 470E (NO 560E)
R12 1K
R13 220E (NO 100E)
C1 22U
C2 CERAMIC MULTILAYER (150p maybe)

Q1 & Q2 ??
Q3 BC558
While R101, C101, C102, C103 are not present onto the board (as far as I see).
Double check is welcome.

A few more shots would clear things up. However, i believe the R101, C101, C102 and C103 may be SMD parts under the board. This would be consistent with Dunlop build methods.
As for C7, my guess would be 1u axial tantalum. Again, the value isn't visible on the photos. C1 could also be 1n. This is based on the guess that all the rest of picofarad value caps may be SMD.
Maybe that's enough guesses? Breadboarding could help.

C1 can't be 1n.. maybe you meant C101.
All multilayer caps are yellow ones (clearly in the picture), so I suspect C101, C102, C103 are in pF.
BTW, what about NPN transistor (which one) ?

Ah! My bad. Typoed the designation. I meant C2. This would make sense as 1n since the 101 etc are most likely in picofarad range. Or it could possibly be 10n as well - as found in some tonebenders to tame the screeching highs from the input.
Again, guesses :) I haven't seen the original except for photos.

Nice! Still, for a build, the 1u will be close enough.
So what we're basically missing is the bottom images and a value for that MLCC. Transistor type is somewhat irrelevant as one could argue other being better than another for days.

R13 ??
what is wrong in 220E ?

I would rather say that that the ring colors are brown-black-black-red which determine the resistance value,FausterCraster wrote:R13 ??

which would lead to a value of 10 Kiloohms.
The resistors R13 together with the capacitor C10 act as low-pass filter.
With a resistance of 220 Ohms gives a roll-off frequency of about 723 Kilohertz,
with 10 Kiloohms a roll-off frequency off about 16 Kilohertz.
This is why I believe that 10 Kiloohms are the right value,
because a low-pass filter with 723 Khz make no sense in this application but 16 Kilohertz is more likely.

do you guys know why they've chosen a 220k resistor inthe cathode follower stage?. it seems pretty high. the original had 22k in there.
i also think the last resistor is 10k. but it shouldn't be calculated as an isolated part...because it's part of a 2 pole low pass filter formed by r12,13 and c9,10.

This works? Any suggestions?FausterCraster wrote:It's verified.
Nice fuzz.

I built one using Storyboardist's layout:
https://effectslayouts.blogspot.com/201 ... -face.html
It's very high gain with overwhelming "bloom" type fuzz and strong sustain. The gain knob is useful all the way and very interactive with the guitar's volume control - like a good fuzz.

There's a newer Dunlop "Gypsy Fuzz" in a 1590B with a tone control.
