Nice find!! Other places for unique tools is search ebay for both Watchmaker/Clockmaker tools and Dental pliers. Yes, they can get expensive for really good sets but for just bending wire the inexpensive ones work fine. I've got both, the inexpensive set was bought to modify. The tip of...

When I learned to solder in the military we were taught to bend component leads and wire with this type of pliers. They can be found at Hobby Lobby type stores in the jewelry section or online fairly inexpensive. Round nose pliers.

With a signal or tone Generator you can put a steady signal into the pedal and trace it through. Alternatively you  can use music or other audio but its very difficult if not impossible to sync the scope to see the waveform or any distortion.

You might also consider either an Audio Signal Generator or a Cable like this with the appropriate phone connection and Tone Generator app. I downloaded "Frequency Sound Generator" by LuxDeLux and it's good so far; very basic and simple to use. I paid for the pro version-you pay what you want...

The best thing to do is just start using it. On the scope it should have a test output, a squarewave. Put the probe tip on that and figure out how to adjust the SYNCronize or Trigger (same thing) for a stable waveform. Also learn to adjust AMPLITUDE and TIME/DIVISION. These labels can change...

Thanks!! However that was more due to poor planning than anything else. The bezel needs an 8mm hole which was drilled by Tayda so I had to work with it. Luckily the legs were wide enough to do what I did. A Dremel would have made short work of it but I just used a fine tooth file. If...

Another Lune. Built per documentation, no intentional mods other than status LED location. Did have to file the leads on a couple of pots for the 5mm Rate LED housing I chose, shown in the photos. Tayda drilled and UV printed enclosure. Artwork was freely downloaded .png image that I worked...

I've had good luck using a potentiometer for this in the past. Just dial in the brightness you like then measure the resistance of the pot, use an appropriate resistor for permanent installation.

With all of this in mind I have to think distortion is not the cause of the difference they are hearing. Then what is the cause? I'm at a loss. I was thinking maybe the resistors have some capacitance or inductance that was a possible cause. So I got out my (relatively inexpensive) LCR meter...

Yes I do understand we currently have a big capability of analyzing audio, but aren't there advances made frequently that continually advance our capability? This is exactly the point I'm making. Another way of thinking about subjective is that it cannot be measured- yet. Just because...

People can be fooled, no doubt, especially when it's your intention to fool them. Alan Funt did this time after time... But proving a person, or even a group of people, can be fooled doesn't prove that no one can hear differences between various components. You proved you can easily fool...

RG Keen is truly a wealth of experience gained knowledge and an inspiration for how freely he shares it. Thanks @owlexifry for posting that. @darwin999 very nice write up. I believe you are absolutely right about noise, the science backs it up. I agree with most everything thing said with...

The common name is the resistive element in the resistor. Metal film is just that, a thin film of metal or metal oxide that is sized (cross section & length) to provide the resistance required. The film is applied to a ceramic core spirally and topped with a protective coating. These are the...

Too bad it isn't 42 or 44 ga, that's pickup winding wire... Very generous of you to offer this!!

<Raises hand> I do!

In that picture I don't see ANY carbon  film resistors, only metal film and carbon composition. But yeah, that's a hilarious description for the resistors. Makes me wonder if he hasn't solved the mystery of time travel in order to age his resistors?

If you have it on a breadboard you might try the B10k with a 10k resistor tied across lugs 2 & 3, then across 1 & 2 to see if either one works for you. The overal pot resistance will vary from 5k to 10k depending on wiper position. I'd be interested in the results if you do try this.

In this circuit the overall pot value needs to stay the same as varying it will impact how Q3 operates. Thinking about it, if the overall value of the pot were to change it would have an interesting effect on Q3, whether it's a desirable effect would be up to you. Might be worth experimenting...

I don't believe you'll be able to keep the overall value of the pot at a fixed value using this method. The overall value is going to change as the wiper is moved any time you tie an end lug to the wiper via resistor or wire. To the best of my knowledge about all you can do to keep the overall...
