Welcome to the forum!
Could you please post some pictures of your build?
Are you using perfboard, or veroboard, or did you make your own PCB?

The schematic you used would be helpful, along with pics. A stock Timmy gain pot is 1meg, measured out of the circuit. Some versions use 500k. You're measuring lots of parallel components that connect those two points, including diodes, internals of the op amp, etc. In-circuit resistance measurement...

There are some gut shots here: https://forum.pedalpcb.com/threads/would-it-be-possible-to-turn-a-sonicake-volwah-into-just-a-wah-pedal.8358/ It looks like a 3-lead red/green LED, could be either common anode or common cathode. You could mark the leads so you remember which is red and which is green,...

Welcome to the forum! If you're talking about the 2k trimmer, it allowed adjustments for any imbalance between the inverting and non-inverting inputs on the early versions of the CA3080. Pins 2 & 3 on your IC. But current versions of the 3080 don't need that, just set the trimmer at 50% (1k/1k) ...

Welcome to the forum! This is a pretty complex build, congratulations for taking it on. Your blue wires from the Bypass switch mini-PCB "in" and "out" holes to the in and out jacks are correct. On that mini board, the other wiring to the PCB looks correct as well (FX in = In, LED...

Welcome to the forum! Could we see the other side of your PCB (the solder side)? Did the trim pot get adjusted during your procedure? Even a small change can stop the phasing. There is a section of stinkfoot's mod procedure page that provides a caution, could this be the issue? "...Then locate ...

Welcome to the forum! This thread may help, it's linked in the "similar topics" section at the bottom of this page: https://www.freestompboxes.org/viewtopic.php?t=25294 If your LEDs are lit but not pulsing, the fault will be in the LFO at the bottom of the schematic. Do the Depth or Drive ...

Yeah, try using all your stock parts, except reduce that 3.9k between emitter and ground. As you decrease it toward 1k or so, your collector bias voltage should move from your original -4.5v closer toward -7v.

Welcome! Could you post the schematic you're working with? Your transistors have a beta in the right range (75 to 100.) To get a correct bias, you may need a trim pot between the emitter of Q1 and ground (stock in this position is a 1K resistor paralleled with a bypass cap.) Yes, the Q1 collector sh...

I can't quite follow your ground wiring scheme - are all the grounds connected in some way? Looks like you are using the enclosure to ground the in/out jack shields, sometimes that works and sometimes it doesn't. A hum with the pedal engaged could be a missing/disconnected ground.

...i have built 15-20 different pedals so far and i thought this one should be easy... everything went smoothly but as i said it did not sound like most of the utube videos i have seen. the main reason that comes to mind is i tried it through a clean amp.... In addition to the differences between p...

Recently, the page selection links at the top right corner of posts (for page 1, 2, 3, etc) have disappeared beneath the content (see pic attached.) Links at the bottom of posts are still visible and accessible. It's the same with either Chrome or Firefox, so it's not browser-specific.

Congratulations! Your first thread completed, with a working pedal, and it looks good too. Neat job on the wiring, I like running those in/out jack wires far apart, against the sides of the enclosure like that, it helps reduce the opportunity for signal leakage and feedback on gain-y pedals. I know ...

Great! Now work your way from the input jack, thru the switch and into the PCB, then left to right thru the schematic.

I think the next step is to use an audio probe to trace the signal from the input jack through the PCB, and listen for where it stops sounding good. That will help you find the problem. There is information about making, and using, audio probes here: https://www.freestompboxes.org/viewforum.php?f=91

I can't see any justification for it. I think I'd set Vref with a couple of resistors (could be bigger than 10k if you want), add a cap to ground, run Vref into a unity-gain op amp and use the op amp output as a common stable Vref feed for all the other op amps. If you use those 4580's, each half dr...

Try bending the sleeve lug of your Output jack (black wire) away from the path of the cable plug. The plug's tip may be touching it when you plug in the cable. It's OK if this sleeve lug touches a pot, they're both ground. Make sure the green wire from the tip lug of your Output jack is not touching...

I've built a lot of the Precision Electronics Clean/Octave Blend version of the Foxx Tone Machine, and have gotten the best octave with: -Q2, Q3, Q4 = 2N5088 or 5089, Hfe at least 425 -Q1 = BC550B or similar, Hfe right around 325-350 (although some people like this one to be >425 Hfe as well) -The r...

This circuit doesn't have a ton of gain, that's why the King of Tone used 2 of them stacked in series. You can add some gain by adding a 50k or 100k resistor between lug 1 of the Gain pot, and the wire that connects to the vero hole A3 (which leads to the 47pF and 3k3 resistor).

Welcome! Your pics got posted, but there's no text so we don't know what you need....
