Ok now I finally know, ty once again for all the knowlege you give us and for saving our pedals, and for the advice of the capital letters!
DO NOT overfeed your pedals.
Pedal obesity is an ever growing problem in the pedalcomunity which takes inocenc pedallives way to soon, leaving us players out of tune, gainless, unhaired and in a state of deep greef.
Raise awernes by buying the new and awesome 'Colins Sexy Guitars' Tshirts and remember, make your sound fatter, not your pedals.
@Johnny Tightlips lol 😂
@@Ndlanding please send me some of the salt you have been taking and also the copy of the jokedictionary you have burned.
I was told not to feed my pedals after midnight, but I did it anyway....
I went back and re-read this in Colin's voice once I saw "unhaired." I was not disappointed with the result
You know you’re paranoid when you watch this just to reinforce your confidence what you already thought was true. Thanks Colin!
I work in the electrical field and I KNOW that mA means milliamps, and I know how all of this stuff works. I still watched it. Gotta know if something changed between now and my last class 2 days ago. Gotta be sure.
Electrical engineer here. Great video, accurate info. Keep it up!
How do you twitch your guitar knobs for different styles and genres?
2:35 The Japanese word for voltage actually translates literally as "electricity pressure"
The Japanese are amazing.
that's... weirdly correct
Great video! One question: what is "impedance match"? I've seen many pedals saying they have their impedance matched for digital pedals, analog pedals and other stuff but I don't know what that means. "Too Afraid To Ask" is one of the best video series ever :D
Well, i have to admit i learnt a lot about pedals today. I don't own any pedalsso I never thought about how they should be pluged in.
I love electronics so you can do more videos about these subjects, I will gladly watch them all.
Another winner! These technical terms explained in layman's language is an art in and of itself! Thanks a bunch as usual Colin, you continually bless us with PRACTICAL knowledge!
All of this electronic talk really Hertz.
Necessary though; it's a really current topic
@@nuberiffic With lots of potential.
Here is a TATA. What does "Warmth™" in audio mean? On like Quantum level? Yea, I can hear the difference, but what it really is?
Also... PATREON NOTIFICATION SQUAD
It's not officially defined or something like that. Normally when people say warm sound they mean a lot of low mids/lows (round about 100-700Hz I would say) and not too much high end (like 3kHz and above). But its a very vague term overall
Low Mids I think, High Mids are presence if I recall correctly.
I have heard something about even and odd harmonics when it comes to for example guitar distortions and overdrives
The short, semi-technical answer is that it’s referring to a particular group of even harmonics. Certain types of circuitry has the potential to produce more than other types.
Colin has the electronic physics degree, he could definitely say more. I just have an audio engineering degree. 😆
When I understood this concepts, I build myself a battery power supply. 8AA rechargeable batteries, an On/Off switch, a box and a Daisy Chain. Now, with my 6 pedals, I have about 6 hours of playing... More than enough for rehearsal, soundcheck, the show and the after jam in a normal night. Plus no 60Hz hum... I´ll be buying bigger batteries as a backup system soon....
Great video! You're the only one who make it all crystal clear. Thank you!
Oh, what an awesome feeling to find a channel that does the best to explain all the things that I don't fully understand. I really find this videos useful. Keep up the good work
Hey Colin! Nothing new for me here but I would really appreciate such a compact and useful video when I was starting out, instead of searching and reading multiple forums for advice. Keep the good work🤘
Too Afraid to Ask
What is the difference between using active pick ups and using passive pickups with a boost or preamp pedal?
Many thanks for all your work!
honestly ... I live for the post-credit snippets lol
Nice one Colin, I like the way you explain electronics in a way that is relevant to musicians but also correct and concise.
Currently learning about all these terms in my physics class at the moment. Really cool seeing Colin explaining it in the guitar world!
You're like my guitarist science teacher. Thanks
Stupid question here: how do I know when to change my tubes? I don't want to wait until the output of the amp drops dead, but I don't want to change them 'too early' either. I've heard people saying you have to change them 'regularly', which doesn't mean anything. Please explain me this mystery!
It is not a stupid question, it is a very good one. I am not the best person to answer that properly, but I saw that you should change them when their top turns into an opaque grey
@@pauloscabeni5277 i thought that only happens when the tubes break and air enters the tube(Collin has a video on it). A loss in audio quality(I think in the high end frequencies) can usually be a prompt to change tubes as well as inconsistencies in the sound and possibly volume, ie one day it sounds like this and the next day it sounds different etc.
V.L.T.R .
the only stupid question is the one not asked... if you tap your tubes while the amp is on they should not make a lot of noise if they do they're having issues in the old days you could put them in a tube tester and find out but those days are gone?
just make sure you get paired tubes and try not to go to cheap some companies tubes sound better with distortion amp gain and some some better for clear it depends on what you play ?

I've been planning ahead on my pedalboard and trying to research daisy chaining, and this has answered so many questions! Thank you!
Teach me about phase on guitar pickups, scottish Sensei
when guitar pickups are in phase, that means their sound waves are traveling at the same time. like, the peak and fall of the waves are happening at relatively the same time. when they are out of phase, they rise when the other one falls, and vice versa. thats my best explanation
I love this T.A.T.A. videos, even though I'm fairly expert in all this guitar related stuffs, I always find something new.
Thanks Colin, once again 🤘🏻🤘🏻
Thanks for the explanation. You answered several questions in one video. Thanks Colin!
I am a fan of your level of knowledge AND your talent for imparting it.
As an electrical engineer who got interested in electronics while studying recording studio tech, I'm not sure why I watched this video. You definitely nailed the info though!
To quote someone from the ‘90s, “You da man” Colin. Once again, you clearly know your stuff, and you explain it well. 👍
A whole youtube video on this topic without using the word "amperage". Legend
TATA - what are tone knobs on guitars, amps and pedals actually doing to the signal? E.g. Stratocaster guitars typically feature tone knobs that when turned makes the signal more bassy; what is happening to the signal that causes this? EDIT: got rid of 'single' tone knob implication; I am not a smart person and forgot that strats typically have two knobs despite the fact I own a fender strat! I blame my other guitars for only having one tone knob!
As a short answer, basically when the tone knob is turned down, it removes some of the high end of the signal. lowering the tone dials will give you a more mellow, and sometimes muddy tone. This can be used to your advantage, however, because if you set the tone on your amp to sound nice with the tone Dial(s) around 6-8, you can crank the high end up by maxing the tone knob if you need to stand out for a lead bit without actually making yourself louder
@@connellphillips5439 Addition for experts: Your tone knob is a potentiometer (changeable resistor), so in combination with a capacitor your tone knob is basically a tunable RC low pass ;)
@@Ndlanding Complete brain fart, my fender stratocaster in fact has two tone knobs, I misremembered it only being one for some strange reason. Not been playing it enough apparently!
This is exactly what I learned just.couple of days ago when I bought a new power supply and learned that I can share one of the sockets between pedals
I love the way this man says pressure lol
Hi!
In the scenario of one power brick with multiple isolated outs:
1. How many analog pedals can we power supply with a daisy chain, without noise interference? (Having enough mA for everyone)
2. If we daisy chain let's say an analog overdrive with a digital delay will we raise the noise floor?
3. Why can't we daisy chain digital pedals?
4. I heard that if you daisy chain an AC pedal with DC pedals it will work. Actually I did that with an old BOSS pedal without knowing that it needs DC and it worked. Why?
Thank you! Great videos!!
Tata is a way of saying grandparent in spanish, so "today i'm takling your TATAs" sounds really funny.
Thanks for your explanation, now I know what I want to know about this. Cheers from Malaysia
Eye opening!
Can you explain the difference in function and sound of a solid state rectifier versus a tube rectifier?
You should totally do a "Too Afraid to ask" about Pickup phase. :D
I wish I had had something like your videos when I was learning to play.
Colin is a good boi with info
this was so helpful and simply explained for ppl who have no background in this thanks! time to figure out if my powersupply is strong enough I have an mxr 100 and that has a 600mA
If I didn't take my basic electricity class in the spring of this year I would have no idea of what you just said haha thanks Collin
This video is the clearest thing ever!
Hmmm, I suppose a question I’ve always wondered about is ohms for amps and cabs. No doubt I could probably look it up but it’d be more entertaining being explained by Colin. Thus actually engaging my limited attention span.
Basically a breakdown of what ohms are, their interaction and optimal usage between amplifier and cabinet. Does mismatching effect/damage anything?
So lastly, this is my Tata, tackle away good sir 😊
The question I never thought to ask but very happy I listened to the explanation.
A perfect niche subject to hit on. I've been wanting to learn a little more about the Current / Amps subject as it associates to pedal voltage ratings.
when I rewired my custom pedalboard I went out of the way to make sure I had everything correct like he was stating it. all my noise went away do not know if this was part of my old problem or a coincidence? but maybe coincidence's it's just as reliable as luck !
don't forget to position your buffers Rock on☆
Hi Colin,
I mostly know how cathode ray tubes work, firing electrons using heated plates charged at a high voltage of opposite polarity, but I'm not sure what they actually do or are used for inside a guitar amp.
Guitar amps don't use cathode ray tubes, they use the more generic vacuum tubes that can function like a digital logic gate. CRT is a vacuum tube specifically made to display an image with a cathode ray gun, that are not used in amps.
god damn, i love you man. thank you for this. been looking for this info for tooooo long
Thank you so much for sharing this knowledge
Simple and full of useful informations, as always. Thank you!
Perfekt explanation. Thanks! 👍
Great explanation, thanks for the video!
Thanks, Colin. I learned a lot from this upload!
I love this explainer.
Love the nerdy vids.
You should be my GCSE physics teacher, way clearer and much more interesting
IT´S CURRENT . NOT..C##- Colin - you´re a Legend. that´ll keep me going for Days.
A possible tata:
I was thinking about connecting 2 separate power supplies in the following order (to power 10+ pedals on my board)
Power source > a T-Rex type fuel tank (has a more robust plug) > T-rex’s 18V DC output > my current power supply’s 18V DC input;
This way it would give me a few extra 9V DC outputs, as I am running out of them and I would not need to plug both of the supplies into a separate power source, only the first one.
Would this work as expected?
How did you know I was going to mention your pronunciation of current? 😂🤘🏻🎸🔥 thanks Colin you cleared up a couple things for me. I knew using a power supply it has higher output was bad. I Was always unsure about using a power supply that has a lower output value than the device requires.
well done, Sir!
Great video and very informative
Thank you Colin , very good information.
Video starts at 2:25
Friendly neighborhood guitar player here, take your daisy chains and THROW THEM IN THE TRASH. All your pedals will share the same ground loop and pedals further down the signal chain will amplify the ground noise of the others. Spending the cash on a supply with truly isolated ground loops is more than worth it. Avoid the cheap “daisy chains in a box” supplies.
This is a really good video. I use a Voodoo labs power supply. I need to look at it again now
Hahaha that shirt is real awesome... or should I say... hyperreal awesome!
Thank you
I enjoy these tata videos. Lol
Tata: What conditioner do you use?
I in fact have bought a few pedals recently, used some old adapters that i tested one was 13 volts and 14 volts and my pedals were fine nothing happened, and these pedals were only rated for 9 volts so i guess they could handle it but maybe higher would be taking chances .I did look into this ma thing and volts and bought the expensive voodoo mondo $390.00 crap !
Well explained man!
Awesome video…I’ve always wanted to know this
Thanks for the physics lesson
Can you tackle on why buffers mess up with vintage fuzz? They go all buzzy and unusable...
thanks a lot dude, this is like the best shit ever
keep it up!
When I first started buying pedals, I foolishly thought all of them drew 200 mA because the power supply the same brand made were 9v 200mA (for the record, these pedals were typically Boss, Ibanez, and Digitech circa 2003).
I love the science talk.
This is something I wondered myself when I was looking for a power supply. Strymon gives 500mA each, but Voodoo Labs only gives 250mA each. I have no idea what that means. End the end, I decided to buy the Strymon Zuma, simply because I figured having 500mA is better than having a 250mA. More is better, right?
Hi Colin, why are some pickups slanted, and what effect does that have on the sound?
What's a ground loop? Like... seriously. What's a gound loop?
Very informative... thanks...
"..questions you are to afraid to ask. This q comes from Bernado Bisio"
made me lol, maybe he wanted to be somewhat anonymous :(
So, power supplier voltage = matching pedals voltage, and power supplier Amperes= total sum of the pedals' one / greater?
Thank you :)
awesome vid thanks
I’ve had pedals say they need 400-500mA but honestly they work just fine with just 100…. The only pedal that I’ve tested that did need more than 100 was a wah. Other than that one I heard no difference…. I’m just cheap and don’t want to buy another power supply probably 😂
It's not a case of "hearing a difference", if a device doesn't have sufficient current it simply won't power on.
Nominal ratings are by their very nature above the average operating draw because it's useful to have more current than required to prevent problems.
Big digital pedals will have a large inrush current on start up that may require up to 500mA simply to boot up, but that demand will drop back down to less than 100mA under standard operation.
I use to have a Daisy chain power supply. But about 2 years ago I got big VooDoo labs power supply.
Alright man, here's mine:
What is the difference between 250K and 500K pots? What do they do, and how are they different? Also, is there a better one for a certain pickup?
a pot(potentiometer....as in "potential" another word for voltage pressure) is a variable resistor and a set resistor all-in-one. There is typically a winding of resistor wire or material whose entire length has a resistance of the pot's rating, ie 250k ohms. There are 3 connections on a pot. The 2 end connections are on each end of this 250k ohm(in our example) strip of resistance winding or material and will always measure 250k ohms on a meter. The third connection is called the wiper because this wiper contacts the resistor material but can move from end-to-end of the strip. So, when the wiper is at one end, the resistance between the wiper and the end contact next to it is zero ohms (a short since wiper is right at contact), and the wiper to opposite end is the full 250k ohms. as you move the wiper, the resistance increases as you move away from the near end, but decreases relative to the far end you are now approaching.
There are also different types of resistive material or winding material and they can make "linear" pots where the resistance changes the same over each similar length of the resistance strip anywhere on the strip, and you can have an "audio" taper where the rate of resistance increases from one end to the other making much of the low resistance end controlled by a greater share of the turning or linear distance and then it sharply increases right at the end. audio tapers are good for touchy stuff like expression and wah pedals where you want detailed control at the quiet end then go full on at the very end, for example.
The pot value in a guitar tone circuit affects the resonant frequency of the little RLC (resistance, inductance, capacitance) circuit which is your pickup(inductor), cap and pot(resistor). the different values give different tonal qualities by acting as sort of a filter and the better pot is the one that you like the sound of better. HTH. rock on!!!
What's the difference between a single coil pickup and a noiseless single coil pickup and if they can make them noiseless, why doesn't that become the new standard single coil pickup with the noisy ones become a "vintage" style single coil pickup?
Pretty sure this information was the missing piece in my grand plot to rule the world!!!
One Point Twenty One Jiggawatts!!!!
Do active pickups drain the battery if they're left plugged in?
The cable when plugged in completes the circuit. This means it only drains power when it has a cable plugged in.
my zoom 606 was more tame when i used 500ma and sound sweeter than 300ma
Please explain lows,mids,and highs
hey colin could you do a tata on feedback?
TATA question what is the crack with Thiele / ported cabinets. What are they actually doing that is different and what are the benefits or disadvantageous?
Oh okaaaay thanks a lot !
Thank you for this video. Helped me a lot o7
Here's my TATA: flipped pickups, are they installed inside out or just turned 180° (if you're looking at someone playing it)? Does it affect the sound (that much)? Practical applications are appreciated :)
So i think its safer to use less MA on power supply to avoid hum or noises......and it wouldnt harm the pedal
