I never did, basically gave up. It seems to not affect the signal noise in a significant way, when it's on it sounds almost exactly like when it's off. I was trying to use it to mitigate a noisy switch on my bass, it seems like it should work, but doesn't!

Using 60/40 solder

The switch and led activate normally. I hear sound at the same volume with both wet and dry signal. When I turn the pot, I can hear a change in pitch (on a noisy power supply) but it does not seem to be gating any noise. I have gone over the solder joints again under magnification, and have...

Not yet, I got mine from Tayda also. Going to try a new one I got later soon. I get basically full signal through the whole range of the pot, with no noise reduction... pretty disappointed right now, doesn't seem to work.

Yes, found I actually got those from Tayda as well. Usually their parts are legit, so not sure what to try. Will try another transistor soon, also from Tayda.

N.p. thanks for looking. The only other thing I haven't checked is the values of all resistor, but I'm pretty sure they're right, although I'm not that good at knowing what they are by band color. I'm pretty certain I checked them carefully before soldering, could a misplaced resistor cause this...

See the slides in the original post, there are some close-ups

Here's the insides: Muffler guts

Or other transistor also...

Ok, good to know. I ordered these parts from a cheap supplier on Aliexpress, so they may be suspect. I have seen other posts where a TL072 was substituted, or other IC. Would you suggest some other compatible IC I might have on hand I could test to see if the one I'm using is faulty? Thanks!

I don't think solder is the problem, I have made quite a few pedals, and have checked the joints on this one closely. I am suspecting maybe counterfeit IC or transistors, possibly.

I built the Muffler noise gate as specified in the build doc, but the signal noise does not seem to be affected by the circuit much, if at all. I have confirmed the transistors and IC are correct by name, as well as capacitors. I checked all resistor carefully when installing. What could be the...
