Would it totally screw up the output impedance on the Rangefinder if I added an A100k volume pot at the end? Just a standard setup. PCB out to pin 2, pin 1 to ground, pin 3 to 3pdt.

Thank you to all that helped here, but I just tossed the board. Couldn’t absorb any more failures. All 100u caps were swapped, drive and filter pots, and the 3pdt were swapped. No dice. Thinking now, it could have been a 5817 that was letting vRef or +18 come backward in the power section? I...

Definitely good to go on leads outside the pedal. I’ve used two different 9v sources as well. Neither of the issues continue to happen when the pedal is in bypass either.

R13 is Brown/Black/Black/Brown/Brown Q1: 1) 5.8v 2) 5.3v 3) 16.1v Q2: 1) 4.9v 2) 5.3v 3) 16.1v Now i'm getting 5.5 and 6.7v on pins 2 and 3 of the 833, and 6.6, 6.3, 15.4v on 5,6,7 of NE5532. All other pins have stayed the same. Getting 6.6v at the R100/101 junction at the moment. Here's a...

I checked the output Jack for DC and it was hopping around a bit, but only at a couple mV. Wasn’t sure if that was enough to constitute a leaky cap. Pictures attached

Just finished wiring up a Bootleg OD and I’m getting crackle that sounds like a bad connection. I physically moved things and poked around but couldn’t find any loose components. Went through and reflowed anything that looked imperfect. Not sure where else to check next. Im not sure if this is...

Man, this forum is awesome. That's super helpful. I don't have a probe, so i'm just looking at the circuit here. Is the square wave coming from the 386 or from a feedback loop through the TM-011? I've done quite a few builds but I still have a lot to learn about how things are functioning haha.

I was planning on building a captain bit for a bass playing buddy and thought I should probably add a blend knob. I was looking at the schematic and noticed 4 of the knobs look like they’re already blending in the effect. If I’m correct there, does this make a blend knob totally redundant?

You guys were correct. Got the 27k out of R20 and popped in a 27r. Works like new! Much appreciated.

Damn you guys can spot a bad resistor well. Much appreciated. Placing a parts order for a few other builds right now so i'll add a few 27r's to the cart and update this post once I pop it in.

Anything obvious that I missed here? I’m only getting signal through when the foot switch is in the off position and the bypass switch is in true bypass, so basically I’m only passing signal through the foot switch. I’m fairly new to this but I feel like the IC voltages probably aren’t where...

I'm going through this build right now and noticing several discrepancies between the build docs parts list and the pcb. Things like R3 being listed as 1k or 100k on the build doc, but 10k on the pcb. Or C1 being listed as 22n on the list, but 10n on the pcb. Any advice on which to follow? The...

Had a baby, couldn’t get back to this until now haha. You were right, I dropped a 1k in R16 instead of 10k. Boxing up now. Thanks!

I’ll check that, thanks!

Looked over my build and I’m not sure why I’m getting a significant drop in signal volume when the effect is activated. All effects are working, and the bypass is good to go. The only problem is the volume drop when activated. I read in another thread about upping the value of R18 to increase...

Thanks! Do I need to buy those matched or can I test them with a multimeter?

Which germanium diodes specifically do you guys suggest placing in D2 and D3 on the Parentheses Mini Fuzz?
