"audio taper pots can give smoother swells when you're fading in from zero." there it is. the question none of the other pot comparison videos specifically answer or address. thank you.
Thanks a lot, David! Much more useful than reading long controversial threads and not always knowing who *really* knows what he's talking about. Some BSers are obvious but not all when you know very little -- or zilch about a given subject.
Here’s my question about this experiment. What is the taper of the audio taper??? Most common audio taper pots are a 10% taper. Vintage audio tapers are 30% tapers which respond closer to linear on the first half of rolling off
Brilliant video! Always nice to see someone who knows what they're doing for real "something that is unfortunately becoming more o more rare these days"!
You seem to be pro linear tapers but I have been considering changing my current volume pot on my fender amp for an audio taper because I want more head room. I don't wants non existent 1.5 volume. And then a holy shit that's loud at 2 and up. So I think you've just helped me make up my mind thanks!
Amps are a different beast entirely, and I wouldn't use anything from these videos (focused specifically and narrowly on passive guitar controls) as a guide for any choices inside an amp.
Who you gonna Call? David the Myth Buster, rolling back, and tapering off the BS so you don't have to hear it. There are so many on YT and forums, who are just giving personal opinions, not facts.This is the facts. Good onya Dave.😮😢.😊.
David, I have some pots on a vintage intrument , that are numbered and are part of the authentication of the vintage etc . . . a couple are dead or almost dead, and long past their due date, really . . Do you think its possible to pry them open and replace the internals with some from a new pot, and seal it back up again or is this pure fantasy? .
Ther is a FUNDAMENTAL thing that all the people forget to think about. THe total CAPACITANCE of the CABLE-AMPLI 1st stage affect a LOT the tone when rolling off .... In this video the cable is quite short but on average i saw cables of 50-100 pf and cables with MORE than 1nf ..... when the POT is at 10 the amp side will see an RC low pass filter where R is more or less the parallel between the DC resistance of the coil and the volume pot value...... so kind of 10k, with a good cable full bright tone. BUT ... whe You rolloff the Volume and the cable is a shit 400pf value the amp start to see an R value in the range of the potentiomenter from 10k to kindof 150k for a 500k pot....... result is you guitar High ends are GONE..... because of the fact a 1st lo pass filter is in place ...... I use a special cable with 20pf per meter and the rollof loss of treble when moving the Volume pot is almost inaudible.
Is there a way to smooth out the volume from 0 - 2? I'm noticing that around 1 to 1.5 I go from nothing to something, almost an on/off situation, rather than a fade in like I get on my amp, and other audio equipment I've used over the years. My pots are audio pots, and the ones I replaced were audio pots as far as I know, and both did the same thing.
This is more of a question than a suggestion cuz I don't know much. But what if you added a small resistor between the pot and ground. My thinking is that if the resistor was small enough you might not notice the remaining signal as actual volume. While the resistor might still affect the last bit of taper on the pot. What would a 2k resistor do?

This is the best video I’ve seen of showing the differences between linear and audio.
Nice augmentation to my knowledge

🤔🤔 one dislike on this great educational video!!!?? what a talented individual
so neat to see how the frequency response changes
Brilliant video!

Awesome! Please don't stop making such videos
Congrats David, you are my tech hero on this! :)

Thank you sir
Very useful video and clear, thanks! :)
another wonderful video. Thanks a lot
THANK you for these video's! fascinating, and clear explanation.
That switch board would make a great pedal as well ;)
I think Fender used the audio taper pots in the their guitars because its cuts off volume more quickly than Gibson guitars I've noticed in my gear.

great info..cool.... just wondering how you are switching between lin and log using the same pot?...
Use some high gain and sustain and roll the pots SLOWLY!! LOW TO HIGH AND REVERSE!!

Is the vertical scale dB or voltage?

murfbass No idea. I solved my problem by putting in Bournes 82 series pots in my guitar for volume. They work perfectly.
by audio pots you mean logarithmic no?
Audio is the same thing as logarithmic
i suspect it is called audio because audio doubles with every 3 DBs of boost and logarithmic counters that.
