The multimeter I use in this video is the Mastech MS8229 - amzn.to/3n0oDB6. (I am not sponsored - this is just my recommendation based on personal experience. I may earn a small commission if you purchase via the link).
In this video, I disassemble a couple different pots (Bourns and CTS 500k audio taper) to show how they're constructed, and explain how they work. I also show how to identify pot values and taper by their markings and by measuring with a multimeter.
**Correction: at 6:25, I said it backwards. Narrower has more resistance than wider. For the same length, a thinner wire has more resistance than a thicker wire. Similarly, at 4:37, it would have been clearer to say "longer length, more resistance". - Навчання та стиль
Now this is what UA-cam is all about! Great presentation, very clearly explained and extremely helpful. Many thanks!
you mean what UA-cam "was" all about 😅
Been working with pots for a while now and this was still VERY informative and easy to watch. Thanks!
Thanks for the accurate, and well presented video on potentiometers. This video is SO MUCH BETTER than most of the others! The great thing about CTS pots is that they can dissipate more power than most of the other audio pots (except PEC) and they can be disassembled, and reassembled to to change shaft length or style and also change resistance elements of double ganged pots.
I do tutorials myself so I know what im talking about when I say this is a very well put together tutorial, more like a small seminar :)
great job
Yes! I’ve actually watched some of your vids on the Cakewalk X2 along with a few others. Very informative and thank you.
I’m just beginning to look into these things and I agree. Thank you John Cooper and thank you chuck for saying the same thing that I was going to say. This video is extremely helpful.
Your videos have been SO helpful. I've learned a lot about the technical and physical stuff that I thought I'd never learn. Thank you so much for sharing your wisdom! I've been enjoying geeking out on these videos!
So beautifully explained and so easy to grasp. Thank you for this elegant presentation!
FINALLY, someone who explains how these things work and how to tell the difference!!! Liked.
hello, i want to say that i really appreciate your effort you put into these videos, these are really helpful!
Thanks for the video. I had problems with my cts pot but your video gave me confidence to open it up and fix it. Many thanks. I was nearly ordering new.
Thanks for your thorough explanation on those potentiometers! I need them to build my own home-made racing wheel, hadn't a clue what they were. Now this solves half of the problem already!
I've been reading about Pots, but only after watching your video do I see and understand how they work. Thank you!!!
dude...you are really good at explaining things...normally, I'll watch a video like this and the person doing it is so steeped in the subject that they just cant or don't bother to explain it in a way that's easily digestible...awesome video
excellent explanations and demonstration on how the variety of pots work and how they're manufactured.
Thanks for taking the time to do this for others. It was very informative and well done.
Thanks John. I went for a new push/push pot (might as well do a Gilmour mod if I've got to change the pot). Not put it on yet but the flow tests are completely different to my old pot, ie they're correct! What a relief, but interesting to know that a pot can die just like that. Love the idea of a troubleshooter vid if you're up for it. It'll save the world from restless nights and brain ache.
Nice video - something I've often wondered about but had no idea how they worked. You explained it very well!!
Thanks, Ive know how they work but your video and explanations really make it clearer in my head on how to wire pots to do different thing
good stuff, man, artfully presented, professionally researched. Loves
your vid posts are like a breath of fresh air for novices like me.
Thanks for posting
Thanks for this excellent tutorial! It is a great help in diagnosing a volume control problem for a virtual organ!
it is so nice to see you are informing us on these simple things
Great job, crystal clear explanation, thanks.
this is the best and simplest video on potentiometer....... thank u sir ........
No BS, pure gold! Thank you! Keep doing this! Rock ON!
Thank You Sir! Bass guitar stopped working, checked everything with multimeter couldn't figure it out. Watched your vid, took mine apart and back together, tighter with the clips. I assume it just was a bad connection inside, works now and I understand pots!
Hi John, thanks for making this video, very well explained and helpful.
Excellent tutorial. Thanks for taking the time to help educate us all.
Very informative! Thanks for taking the time to produce the vid.
Natural teacher at work here. I came here knowing what a potentiometer does ....always wondered the what & how? In ten minutes I learned so much targeted information! Wow, thank you, johnplanetz
Very, very helpful John. I learned a lot. Best wishes and thank you.
Very precise and awesome presentation
Very well explained in layman's terms. Greetings from Kolkata, India.
Thank you I really had hard time understanding how pots work but now its piece of cake thanks to you :-)
cheers mate, this really helped with my coursework
Perfect explanation, I'm sharing it on my facebook and twitter for my students. Thanks!
Ahhh very cool man!! TY for that video. I have a 16 watt tube amp I bought from Tube Depot and I'm on my 3rd Potentiometer. I keep getting the ones from Parts Express and they are total crap!! After watching your video now I have a better idea of where to look for a better POT . Thanks again!! Looking forward to watching more of your videos. Take care
Really cool video man. Thorough and simple.
Thanks for the video, pots make a lot more sense now.
Clean explanation. Makes sense to lay-folk like me. Nice work!
great explanation simple and easy to understand...love electronics
Love your videos. Thank you for your time and the shared knowledge.
This is a really well made video.
Thanks John!
Fantastic videos mate.
Nice work I really enjoyed your video!
great explanation of pots....nice one man...
Excellent Video, very complete!
Thanks for putting the time in this very well done video : )
Awesome video man!
Thanks for sharing your gift for teaching!
Is for this I prefer linear for volumes and audio for tones, imo and taste this way you can get a better control over each one. Nice video!
Excellent video, thanks.
I thoroughly enjoyed this video John. Thank you for making it. It was VERY well done. I've got a rheostat on a ceiling fan that only has two lugs. I think it's bad because the fan spins very slowly across the whole range of the rheostat. It's soldered into place so I'm going to take it out of the fan (circuit) and test it with my VOM. If I can tell it's bad I'll go to the local lighting store to see about a replacement. It should work much like the ones you tested in the video, correct?
Super Clear! Thanks----
Very well explained.
Thanks
Very nice tutorial. Thanks.
Thanks!! I am going to make a little headphone amp using this. If I where to attach the input in one line of tabs and the out put in another then bridge the two, would that work?
Very well explained. Very useful video!
Really interesting and well explained ! congrats ! I am into vintage pots for a 52-59 LP conversion and wonder how much they have an effect on the sound. Bonamassa, highly knowledgeable on 59 bursts says that the central lab pots play a major role (50%) in the sound of these guitars. Do you believe the quality of a pot can be that important into the sound ? Same question on old bumble bees...If you have ideas, or opinions, I'd be interested. thanks a lot.
Well explained my friend. Thank you
Great video, thanks for educating me
Thank you Mr. Cooper.
very useful informations I have found here! Thanks!
Thank you so much for taking the time to rite me back and i find your reply rely helpful, thanks.
Thanks for sharing this info. I am currently researching for a project. I am going to update an antique radio and am looking for details about how to choose the right parts for volume control, and radio dial. the radio dial i want it to still show the pin pointing at frequency but also send a digital signal to the raspberry pi, i believe that part is a rotary encoder. any suggestions on parts or similar projects would be greatly appreciated. thanks
My physics teacher threw a potentiometer on the speakers for the announcements. Turns the volume down to minimum and continues lessons... best hack ever.
John, I am really pleased to have found your videos. I've built a couple of guitars; but, always find myself wondering about the "hype" when it comes to pickups and electronics. I believe watching your videos will teach me to make the correct decisions. In the meantime, while I'm learning, I have a 1988 G & L Invader H-S-S that seems to be crackling a little. Any suggestions on what to replace and a good source for the parts? I would keep the original sound; but, if I can gain some tone???
Thx after your vid here i did managed to "repair" him. Thx. Works again flawless
well explained john
great video: does the pot need to be disconnected from the guitar electrics in order to measure its resistance? Or can it be done while the pot is soldered on the circuit?
excellent teaching, dude
I appreciate this video. Fantastic, thank you.
Thanks very much. You explained it very well :)
excellent explanation
thank mate you are spot on i had some cts pot 500k where well under not now i did what you said now they are over 500k now thanks
Well explained 🙏
Thanks, I learnt a lot from this.
Nice explanation!
Very good videos. In one of your other videos showing an epiphone circuit being request, you have actually removed the pots and poked them through some aerated cardboard... But you didn't mention it ... That's actually a fantastically useful approach when wiring without a scratchplate... Keeps the work still and even allows you to draw the wiring between the lugs... The latter might help if you are just starting soldering.
Great explanation
Thanks you for amazing video👍
This is very usefull, Thanks. Ive got a fairly old Sony AV amp that has a bad volume control, it loses a channel and crackles when you turn the volume control. Would it be a similar potentiometer? I didnt know they were this simple. Think after watching this il give it a go and see if it'l clean up. Cant afford to lose the amp as it'l cost me a fortune to replace, its a great amp.
thanks man, for such a tutorial
Thank you for this video! Which pot do you prefer? Is one smoother than the other by feel and taper? Thanks so much!
All The Best,
Sam
Thank you! You are an awesome teacher
Phenomenal, thanks for the video!
Hi John,
Do you know what determines whether there is a centre detent on a Bourns pot?
I would like to add a detent and I wondered if it's simply a case of bending a piece of metal
Thanks
Great video!
I enjoyed your video. It was very helpful. Thank you!
Awesome vid,I had a super smooth 250k Volume pot in a Left Handed Ibanez RS135 that guitar did[very soon after buying] became sort of strat-like in looks,but not-before I stripped the 2mm resin[joking] and reshaped the body.I re-used the stock 250K volume pot.even after hacking a Seymour Duncan JB Humbucker-tilted,sounded superb,but that wonderful Vol. Pot. Wore Out 24 years later [great run!]In 2009 I eventually got from the US some 500k CTS Left Handed potentiometers-anyway man they're all irritatingly STIFF[no more"Cathedral"attempts since!],so Thank You for confirming why they is so!
Great Video, helped me a lot. Thank you very much.
Thank you very much John Cooper.👍🏻🌟🌟🌟🌟🌟
Great video. Thank you for making this.
Learning. Thank you brother.
👍Very well explained.
Great video, thanks!
very clear Yoda. thankyou
great vid!! so that's what A and B stands for!
Phily Cheezesteak A= audio, B= linear
Great video, thanks for sharing!
Yes! Now I know why the volume on my Quasar black and white tv ain't working. Thanks, JC.
Great job. Sorry I'm late to join you. You're an excellent teacher. I hope you're doing it at a college somewhere.
This helped answer many questions I had..
