So I just looked at your build and R4 is 100K.
Brown, Orange, Black, Black, Brown is 100K.
I did a double take after responding above because there are no common 133k resistors which should have occurred to me immediately but it is late and it did not.
So you cannot measure a resistor in circuit. I must assume that is how you came up with 133K.
So back to the trimmer I would consider upping the value.
I would still like to know if the potentiometer (working correctly) has Lug 1 (back side – right lug) connected to the main board Pad with the 1 silk-screen for obvious reasons.
No I think the pot wiring issue was my fault due to my orientation of the in the enclosure. Here’s a picture of how it was wired. It works as it’s supposed to now that I switched the black and red wires.
This is where I got the 166k is what I meant.
Those R4 resistor bands are Black, Black not Blue, Blue and Orange is the 2nd band not the multiplier making it 100K but I see your mistake and completely understand. Just remember to try it the other way if you get a strange value.
Also we have these wonderful Resistor band cards you can download from the Guides Page to use. It makes it nice to just hold the card up to the board or computer screen for a quick double check.
The idea behind that was to get more newbs to help troubleshoot on builds here on the forum but so many people would still rather lurk than score a win I guess.
Look man, (rant)
Oh and by the way those are blue bands!
To be perfectly clear I never called you a newb.
What I did say is that I came up with the resistor picture card so that “Newbs” could help participate in helping me and a few others around here in debugging builds.That had nothing at all to do with you. That said “Newb” or newbie is (slang) for newcomer, someone new to something. It is not derogatory.
No excuse for your use of foul language which I had to edit. You are welcome to express despair but don’t be attacking me because you want to insist on your own misguided findings.
Finally I do not do “alternative facts” on this forum so as not to hurt your feelings.
I am here to help figure out the problem with plain facts.
The fact is that the picture you provided me with is absolutely a 100K resistor at R4 with Black bands and not Blue. Even if you thought they were Blue it would still not make sense because there are no common resistors of that color band or 133k / 166k values. (see image below)
I am pretty sure I will have a general consensus on this.
That is the only way to move forward and solve the problem.
First thing I’d say is keep calm Chad I didn’t actually read it as a reference to you
As you probably know people who are new themselves actually call themselves newbs or newbies so definitely not derogatory in the DIY community we were all newbies at some point
I’ve been on this site for 15 years and never had a problem with the quality of the boards or service so I’m reading: you’re understandably frustrated, but calling Barry’s pcb a pos is more of an insult than anything he’s commented especially when he’s trying to help you
Now I’m not implying anything but it’s a fairly simple circuit built by many including me I’ve probably built at least 12 of these not all without problem I admit but usually with me it was an error on my part
I understand frustration, I’ve built many complex circuits but as I say the fuzz face is defo my achillies heel and usually gives me the most problems with over 500 builds in the bag
Every member and moderator is here to help so I’d say the apology should be yours from what I’m reading
I work full time doing fairly heavy shifts I don’t get paid for moderating Barry looks after us with a few freebies here and there in fact he’s way too generous most of the time, as I’ve mentioned to him many times to no avail
So you’ve gone on a bit of a rant to a guy that’s all about his customers hence the reason I remain on this site 15 years down the line
It’d be a lot cheaper for me to buy in the UK being in Scotland but Barry’s always been a top man with me and everyone else
Obviously we’ve no idea of your experience unless you tell us or we ask
When we ask for anything it’s because without seeing the same as you it’s difficult to help
I can guarantee you if you get it going we’ll be as happy as you, so take a breather maybe step away from it for a couple of days and go back to it and we’ll still be here to help
And I’m confident you will get it going
OK everyone sorry for being a dick. This pedal really tested my patience! I would like to continue and get the dang thing working! Thanks to everyone for the help thus far I really do appreciate it! Cheers?
So for schlitz and giggles I powered the pedal with 4.5vdc and the Fuzz works but only with the Fuzz know turned to max, back of more than a 1/8 or a turn and no Fuzz. The Fuzz is very short lived no sustain.
Also Barry I wired the volume and fuzz pots to this diagram and thew worked backwards. Swapping the 2 outer leads fixed this.
Chad – “So for schlitz and giggles I powered the pedal with 4.5vdc and the Fuzz works but only with the Fuzz know turned to max, back of more than a 1/8 or a turn and no Fuzz. The Fuzz is very short lived no sustain.” – that’s standard behavior for most any fuzz circuit with a “starved” battery (lowered DC supply). The transistors’ operational thresholds are being lowered to their minimal thresholds and gating, sputtering & other unpredictable behaviors will occur.
Yep I figured that was what was going on but at least I know it works right? It just won’t bias below -8.76vdc…
Lift a leg of R4 out Chad then with no power to the circuit check resistance on it
And we can put the blue, black, 166 or 100K to bed
These metal film resistors can sometimes be hard to read even under magnification the colours sometimes run or bleed into the light blue during manufacture and make it hard to see I’m still unsure whether it’s black or blue even zooming in
Anyway as you’ll know if you’ve read RGs technology of the fuzz face it’s part of the voltage feedback biasing circuit whether it would have a dramatic effect I don’t know I’ve only ever lowered the value in the past an increase in value would obviously affect current
But defo worth double checking

I will try that this evening after work but I have no doubts your right. Thanks
I’m not as confident haha
Anyway if you can lift the bottom leg I can’t see you’ve said you’d reflowed joints anywhere but the bottom one looks a wee bit chalky so could be dry inside
Well it’s a 100k. It measures 104k.
