    i don't know about the Alpha pot that you measured but Alpha make perfectly usable log pots.
    Something that most people do not know is that most pot manufacturers make 'log' pots with at least 6 different log curves. These are described as 5%, 10%, 15%, 20%, 25% and 30%. Not to be confused with tolerance of the end to end track resistance, these percentages refer to the percentage of the total track resistance when the pot is at half its rotation (measured between the counter clockwise tag and the wiper}. Unfortunately most pot resellers do not tell you which log curve the pots they sell have. Pot manufacturers seem to regard pots with either the 10% or 15% curve as being 'audio' taper. I have seen at least one guitar parts store selling what they call True Vintage Taper, which are 20% log curve. I'd recommend 10% log curve pots for volume and 20% for tone. The tone control response on typical guitar electronics is a bit odd because the resistor / capacitor of the tone control circuit interacts with the resonant circuit formed by the inductance of the pickup and any self capacitance and other capacitance that is in parallel with it. A 20% curve tone pot compensates a little for this.

      Note- that’s not to say that all Alpha pots will be like this! Maybe I just had some bad samples, but the point is that there there may be some variability, so it’s always good to test (and measure if necessary!)

  • @DavidQualls
    @DavidQualls 11 лет назад +2

    Thanks, John! Great job! To "nmssis": A 500k ohm pot for example, with +/-20% tolerance, means that the value of a so-called 500k ohm pot can actually be anywhere from 600k ohm (+20%) to 400k ohm (-20%), or anywhere between those two values. The only way to know for sure what the actual value of the pot is would be to measure resistance across the pot with a multimeter as John has clearly demonstrated. Hope this helps.

    Excellent - Best demonstration video I've seen on the difference between the linear and audio/logarithmic taper. Many videos get the explanation backwards in terms of the perceived difference. When the resistance is changed in a linear fashion, many videos explain that the output will change in a linear fashion. But that's not how our ears hear in terms of volume (due to the logarithmic nature of our hearing which accounts for the logarithmic nature of the decibel measure). This is also similar to why amps have to increase the power (watts) by a factor of 10 to double the volume in decibels, rather than just doubling the watts.

    I'm glad that you made this video. I always get linear and audio taper mixed up. I like to play Van Halen and an instrumental solo called "Cathedral', if you've heard of it. He does a technique with a combination of volumes swells and delay to create a violin or cello sound by rolling his volume pot back and forth.He uses linear taper pots for that because he needs a fast attack and a fast roll-back on the volume.

  • @mikefarquhar5063
    @mikefarquhar5063 Год назад +1

    I think big guitar brands, not only Gibson fender
    (I like them both but facts are facts) who buy 300k pots have cottoned on to this inconsistency regards to the resistance chart, and in mass production then decided to buy in bulk knowing they'd be closer to 250k or 500k and only the most expensive custom shop builds get the most accurate and balanced ones.
    The rest go into the "within acceptable margins" groups of guitar models. Without testing for the resistance value as much, with no stamps of resistance values they can order from the manufacturer, we can order from the manufacturer! A bag of pots with our own brand so testing them yourself is the only way to make sure.
    Dunlop are a good choice I didn't see them on the resistance/knob position and sweep chart.
    I believe they are quality components, plus you could always make the difference after testing the resistance curve values, fill the gap in resistance with a small resistor, after all a potentiometer is just a variable resistor with a certain amount of resistive/conductive materia, thos is very handy for solving SSS pup configuration to HSS pup configuration if you use 3 of 500k pots and a either a 2 or 4 pole superswitch, 470k resistor one or two I used one, on the middle and neck tone control soldered just like the capacitor- casing to outer lug, two resistor of same value means more soldering and it doesn't matter as long as the single coils see closer to 250k

    @ozboomer - I found Bourns pots at guitarelectronics. They also sell CTS and Alpha. No wonder there is such a debate about whether to use Audio or Linear taper pots on the tone position. It totally depends on the brand. You'd think they'd at least be sort of close.

  • @Dan-Nicolas
    @Dan-Nicolas 13 лет назад +1

    Thanks! Only for me it's more interesting to see what a pot does turning it down from full open to a max quarter turn back.
    When playing I turn it about a quarter back to clean the amp up and then turn it open for a solo. On an audio pot that last part sometimes can be a bit too sudden so there is a too small turn needed to get what I want. Then a linear pot works better because that last part is more smooth and you don't need to be so exact. It would be great to see a video of you doing that.

    I have 2 Donner DJP1000 Jazz guitars and the Pots on the Tone are poor. They basically kick in about no 2 then no audible difference. Cheap pots I'm guessing linear . So I've ordered 2x CTS 500K vintage Audio taper and 2 x CTS Linear 500k I was going to try a set of each in the guitars. Now seeing your video I can say it has to be Audio taper so the other 2 linear I will return.I've been trying to research what I need . Your Video is brilliant and the demo explains everything. Thank you.

    • @johnplanetz

    Great video! I love tutorials and teaching content on all things I'm interested in, guitars, sound and vision being relevant here, so thank you and I say this with gratitude because I was so close to buying what I thought would be accurate as advertised- audio taper/ logarithmic sweep potentiometers but very likely to be more of a small percentage different in relation to linear pots, I've made that mistake withkut the knowledge it wasnt 100% my iwn fault. These i bought for my stratocaster style guitar build projects, which I would have been disappointed big time if I hadn't looked up on the how what and why and in this vid specifically the whos responseible pots are different only to discover two out of the rest are actually log-A pots.
    I first noticed with my current SSS pup configuration - no names pots mini pots with an "a" stamped on the tone pots and a "b" stamped on the volume pot, and then after buying all necessary components for a new HSS loom I built from alpha pots that the sweep on pretty much all 3 on both looms/pickguards sounded just like how you had demonstrated in this video on the lack of consistency of log-A pits depending on the brand name.
    So I am familiar with Bournemouth they do a lot of very different electronic components, and potentiometers are, if not the least, they are in the least complicated group of components in terms of purpose and design function.
    Electric guitars are very simple compared to most gadgets and gizmos, but the waiting list on bournes website for a bag full of potentiometers is quite long, snd best bought in bulk but still more affordable than if through the middle man market.
    Mist people including myself have to search, study content look for consistency, scour the Internet or if lucky you live near an outlet or find an honest dealer that will sell you the ones that have already been tested and matched, labeled and the added to a detailed inventory.
    I mean it's not aerospace parts we're taking about here (which I think Bournes do make some components for)
    So these parts are not high priority but still obviously a huge market especially for the music industry including amps to mixing desks, guitars to multi effects units.
    I very much hope you would if you can or do have, share a source outside of Bournes and just like I said have the pots already checked and separated and won't rip people of, for this I would be very much grateful.
    Kind regards,
    Mike.

      I don't know a source that individually measures and checks the parts for you. (But I imagine they do this if you buy $$$ boutique wiring harnesses). Meanwhile, you can certainly order Bourns and other pots at mouser, digikey, etc- and just buy a few extras and measure them yourself before installing.

    It also would help to hear the difference between those pots "from 10 to 0", you know... when you need to drive your amplifier from the crunchy to the clean sound or viceversa, directly from your guitar, when you look for that precision that matches your needs (some need high rates of volume loss, some need low rates).
    If you'll decide to do that video, please show a close video recording of the pots whyle another guy is strumming the guitar on the crunchy to clean border of that VT30 ampli. Thanks all the same for this very useful video.

    I completely agree with this. I compared Alpha and CTS A250k and A500k pots... A500k works great for volume, but I found that the A250k give you much more control over tone. I made this change on my PRS SE Santana with Santana III pickups... The Santana III's are not really bright pickups to begin with so the 250K vs 500k is not noticeably darker. I will be trying the same thing on my LTD EC400 with Gibson 496R/500T, but I plan to try an A300k instead.

    Thank you. No fuss, clearly filmed, easy pace but not dragging and not over-nlown with ego... Your excellent and lucid explanation not only affirms what I believed, but warns me to be more selective about the pots I intend to fit. I have a Vintage V100 which is essentially a Les Paul sort of form. Presumably I need to buy the same value (500 in this case I think) pots even though changing from lin to log? Being a perpetual Fender user (until I found this lad) I like my volume gradual for various reasons; not least being able to roll off a little for quiet passages. The latter despite gentler attack/no pick etc as a pot that stays at ten sounds like it's on ten.
    I have no intention of changing the tone pots adn I suppose I should watch your next vid (I will anyway) but the other question I run into is whther the tone would be affected? Ah, I know starts clean up any over-drive/distortion/call it what you will when you roll off. Fine. But will my woman tone, bark and other Gibsonesque attributes turn into Fender tones (not desired, I already have a Strat:)? Thanks again Mr Cooper

    • @johnplanetz
      @johnplanetz  8 лет назад

      Yes, if you're changing the pot just for taper, there' s no reason to change the resistance. Changing the volume pot taper won't affect the tone. Changing the resistance WILL affect tone- lower resistance rolls off more high end. Higher resistance are brighter. As always, I recommend buying a selection of parts, and experimenting with alligator leads until you find the one you like- and only then solder it all together.

    • @AlexJOliver
      @AlexJOliver 8 лет назад

      Thank you, very kind of you to answer (if I'd thought you'd already said so) someone treating you tube like it was a forum:) I realised I'd mixed taper and resistance up anyway and playing with my tone pots I realise I'd prefer them to be log too. It also occurs to me that I should measure my existing pots, since they produce tones I like. I should therefore try to replicate that, but in logarithmic. I have some cardboard....and thank you, I am hugely confident about my pot choices now. However the postie just dropped off the Stetsbar vibrato tailpiece...

    I'm working on a custom mod of this right now. I've tried the V-treb mentioned below, but I want a higher rated cap for the treble bleed. So I will be trying .002uf, .0047uf, .068uf, and .01uf on different Audio Taper mini-pots rated at 1K, 5K, 10K, 20K, 50K, 100K, 250K and 500K. Also, using a regular pot allows you to put the control at your finger tips instead of having to access the back, or inside of the wiring cavity.

    @duroxkilo 3 года назад

    the resistive track is not symmetrical on an audio taper.
    the beginning of the track has one curve, the end has another, so it matters how you connect an audio pot in the circuit: you want to use the 1,2,3 pins so that at first you get a slow increase in resistance at low volume and a fast increase at higher volume.
    wire it 'backwards" and the pot doesn't work as it should.
    a linear pot has a symmetrical resistive track so it can be wired 'backwards' and still works the same.
    pls correct me if i'm misunderstanding this matter.

    Beautiful video.
    So basically we should buy Audio Taper pots for Tone and Volume knobs correct?

    Thanks, John. That simple demonstration makes this so much more informative than what I've seen so far. May I ask what setting the multimeter needs to be on to test a pot?

    My stupid question : does the tone pots react the same ?

    • @johnplanetz
      @johnplanetz  4 года назад +1

      Yes, similar for tone. Try both with alligator leads to compare

    I seen at 5:05 you determine the diameter of the case of the pot. Does it matter? for example my stock minipots are 8 mm thread ,10 mm long and I found on Thomann(I live in Europe) standard size pots, but with 8 mm thread and 10 mm long. They will fit,right?

    You would think from the smooth line graph of the linear, they would be the ones with a smoother transition. So do most people use audio taper for Tone & volume?

    You've just answered an on-going major drama I've been having with using what are -supposed- to be log taper pots... Those crazy Alphas sound linear to me :) So, I'll have to try the CTS and Bourns brands. There are a number of on-line places that sell CTS pots, so that's Ok... but where can I buy these Bourns!? Thanks again for saving my sanity :)

    Hi John. Thanks for the valuable info. My question is about bass guitar, pickup selector vs blend switch. My bass have a pickup selector, and I want to replace it to a blend switch and still keeping the sound as before? Is there any Blend switch that will give a good balanced mix without dropouts of volume between the pickups and the variety of tones when moving it around?

    Excellent video. However, to clarify, lower resistance in a shunt circuit (volume potentiometer) reduces bass, not treble. It decreases the time constant of the circuit (the time that capacitances in the circuit charge and discharge). For series circuits (tone shunting rheostat that has a cap and pot in series) will reduce treble when resistance is decreased. The opposite is true for both of the above scenarios if resistance is increased.

    • @johnplanetz

      @td1238- with passive pickups, using lower resistance pots for volume/tone increases the load-to-ground on the pickups and results in reduced treble. Using higher resistance pots reduces the load on the pickups, and preserves the highs. I don't really have the expertise to explain it electrically- but the effect is easy to observe in practice. Try the experiment using alligator clip leads to connect your passive pickup to a volume pot, and out to the jack - then swap between a 250k, 500k, 1M volume pot. The difference in treble is dramatic, with the 250k pot sounding much darker/warmer than the higher resistance pots). Of course, none of this applies if you have active pickups, or some other active buffering (like a powered boost circuit) in between the pickups and the volume/tone controls.

    Hi ... Excellent video .. I wanted to know how I can gain more control over my live playing. I need to boost my sound, and i would rather boost by turning up the on board pot. The problem I have is that I play both gain and clean sounds. I have a decent amp with boost. but in higher gain situations I do not get a good vol boost, but just an increase in distortion which is not desireable. I've considered switching out to a log pot in order bring a more dramatic vol increase and decrease.

    John, I learned so much from all your videos!! Now here is an idea I had for working around the tolerance of pots. If I want to have a 500K pot Why not buy a 1M pot and put a resistor in parallel to make it as close to 500K as possible? Say the pot measures 850K instead of 1M, I put a 1M and 2k2 in series and that in parallel to the pot to get as close to 500K. Do you see any tonal or usability drawbacks to this idea?

    Hey John, you mentioned that you ran into Asian pots that were a different size than America ones. It could be that they are actually metric thread. Many countries are adopting the metric system for parts sizes and many things that come from Asia are metric. Many are very close to the North American sizes but just enough off to be frustrating. Nuts jamb up, holes too sloppy or too tight.

    nice on again john. 500k a defo. for all guitar pot volls. 250k can mush the sound and does . i use a 1meg log for violining gives easy movement of sound.

    I want the volume knob to act more like a output control than a volume control if you know what I mean? I just want the pickups to get cleaner when turning down the volume and have the volume to stay pretty fixed all the way down. Is that what Linear pot does?

  • @JMelodic
    @JMelodic 14 лет назад

    So I bought a CTS audio taper pot to replace my linear tone pot, but my original pot was of the smaller import type so I had to drill the hole bigger to get it to fit. I also noticed the original knob wouldn't fit (it's the type with a screw not a Gibson speed knob type) so I ordered a new pair of knobs. Problem is, I like the linear taper volume pot and don't intend on replacing it...will a USA type knob fit on an import type pot?
