These are the videos I’ve been looking for. Thanks for creating this series!

5000 k resistor? did you mean 5mega ohm? 🤔 Thanks!

This dude is awesome

Well the capacitance of the humbucker does not make sense to me, the inductance will double but the capacitance should be the half of the single coil.

It's awesome!

Cant a similar sound be achieved with an EQ pedal?

at 10m10s you say that "an opamp tries to keep the voltage on its 3 terminals the same", that should "an opamp tries to keep the voltage on its input terminals the same" ;-)

How can I get in touch with you for a potential pickup related project?

why is the bias on the input transistor & the phase splitter on a VR? tweak-to-taste? what is the effect of altering it?

I would love to see an explanation of gilmour's "seagull" noises, which were originally created when he plugged his strat (& it only seems to work with strats) into a crybaby the wrong way round, i.e. guitar where the amp should be & vice versa. it's something to do with creating a tuned circuit involving the output stage of the wah & the tones controls & pickups of the guitar. I hid a toggle switch under the treadle of my guitarist's crybaby so that he can summon the seagulls whenever the notion takes him. here:ua-cam.com/video/OcDiOUQBFd4/v-deo.html

The input impedance of your first stage buffer is approx 100k because of the VRef supply resistor in parallel with the input 1M resistor. This will load the pick up too much?

Good to see some objective and quantitative understanding - well done, there is so much BS in the guitar world. My only comment is that the pick-up model is a 'lumped' LCR model, I wonder what difference a distributeded model would make, I suspect not a lot but it would not be easy to model.

Pode me vender um ja todo produzido?

You sell pcbs for this project?

Analog kick drums, are based around twin-t oscillators! Although... these oscillators could probably be thought of as active twin-t filters, that have their resonance pinged by a short trigger. So you're probably still right!

Great video and precise explanations!

Great explanation, like why the resistor is so high to bias the op amp, after watching this video im starting to get a better grasp on these simple circuits. Appreciate you sharing your knowledge and time!!!

What is the inductance of these pickups (approximately)? You state that it is considerably lower than traditional coils (which are over 1 Henry). Are these on the order of 100 mH or more like 10 mH? I am asking because such values are considerably easier to source as ready-made components (albeit at higher resistance). With active amplification, potentially one could design something where one does not have to wind the coils. I always found that to be so tedious :p

Sounds good, and very nicely explained! Thank you especially for providing all the schematics, files, and instructions. I sent a little donation your way as a token of appreciation. Btw, are you planning a ready-to-build kit for this? It seems that at least in humbucker form, the transformer could be integrated on the pickup PCB, then it would be a bit easier to build.

What is the approximate inductance of these coils? I have been wondering about low inductance pickups for a while now and this seems to be a good example of its feasibility!

I have a landtone diy from amazon with a similar circuit and I’m trying to increase the depth to make it choppier (the sound doesn’t entirely fade with depth maxed), should I increase the resistance between lug1 on the depth pot by putting a resistor between it and ground, or increase the resistance on lug3? Would changing the .47 cap right behind it work? And can you replace that RC pair with a red LED to get the same effect? This video was super helpful, I’m just still trying to figure out if the voltage that feeds Q2 is correlated or inverse to signal output. I’ll check out the previous video to make sure.

Why need for startup circuit when pg2399 datasheet table 1 explicitly states that 0.5 ohm is ok? The chip invalid state is probably caused by some other design considerations. Ok so a few seconds later I see it is because of Vref manipulation. So the high pin 6 resistance is actually required to workaround Vco startup

I would love to do this with a 7 string guitar. Howdo I do this same thing with a seven string setup? do you have a kit for that?

Just something I'd like to mention that Strats and Teles almost always have 250k pots for volume and tone and the tone capacitor most of the time is a 47n cap. Longer and cheaper cables can have higher capacitances too which also changes things in your simulation. Other than that it's a cool video.

Great video! Is there a way to stop the movement of the waveform? would benchtop's present the same problem? Thanks

What you call the definition section is actually your global declarations. Variables defined here are what consume the global variable space you later refer to. Everything defined here is accessible to every function within the program, some of which may be variables, but also macros that are expanded at compile time to (hopefully) make code more readable and repeatable. Variables defined within functions are not global and are stored on the program stack and only exist while the function is executing, unless declared as 'static'. The loop() function is not the same thing as main() in C, which is always the main entry point to any C program. The Arduino IDE kinda hides the main() function from you. The main() function looks something like this:- int main( void) { setup(); while ( true ) {. // Infinite loop until we power off or press reset loop(); } return( 0 ); // return a result code to whatever launched this program. Irrelevant on a a microcontroller as the above while loop should never normally exit. }

I tried sharing with some big guitar and pickup sites and my posts were deleted ..... I will suppor you here in anyway I can ..... you are on to something with you pickups!!!

Any serious guitar player would want this after hearing it!! FANTASTIC and something I never even thought of as a muscian. Each one should sell for several hundered dollars each from the audio.

why are you using 2 small coils instead of 1 large coil?

really good video buddy, you have a really good youtube channel, keep posting videos… I’m following you now. thanks 🤩

Great video ! I will use ch32v003 which is 20cent and compatible with the arduino code also !

My problem is I want a pickup with a different frequency response curve from those you get with humbuckers and single coils. I've used just about every type of pickup in my guitar builds. In the end, everything falls somewhere between a humbucker and a single coil in tone. For a while I put 7 band active EQ's on my guitar builds in lieu of tone controls. I even built a guitar with interchangeable pickups. Now I tend to use high output passive quadrails, and a decent EQ at the front of the pedal chain. A decent EQ can make any pickup sound like just about any other pickup - maybe not in an A/B test, but good enough to fool an audience. I'm especially disappointed in Fluence - great technology - and they use it to reproduce "been there - done that" tones. Is it possible to design a pickup circuit with a flat curve - or better yet a scooped (cut) midrange?

Thank you so much for sharing. Last year I built a midi controller with Arduino as my first project and loved it. I've been thinking about doing a looper for a while but didn't know how to do the actual switching. You've given me the missing pieces :) Thanks again!

👍👍👍

Really nice, you take the fear and snakeoil out of what is really basic physics👍

👏👏👏

❤

This is grerat! I'm binge-watching your vids, mate👍😄

I´m 56 yrs old, educated and well versed in the topic after designing circuits since the 90´s, so I´m not easily impressed. But this is the most comprehensive, to-the-point and at the same time pleasant run-through I´ve ever seen on debugging! Moreso, I learnt useful stuff 😃 (That's why I´m always checking in on stuff like this) You know your stuff, AND you can explain it👍 This made my day - thank you! ☺

Man, you´re bloody good at both tech and teaching - THIS is why we have the web! Cudos! 😎

Excellent explanation. Thanks!

Where is the tone shaping circuit?

Wasn’t the flat response the initial idea for active pickups then people could use a parametric EQ to dial in their desired tone. Don’t get to technical guitarist are cave men that prefer to eat a lump of shat on the ground vs a filet mignon .

Como puedo adquirir ese producto?

Awesome video! So much great info. My name suggestion would be "Table Tennis" I'm a sucker for alliteration haha.

“I know that you believe you understand what you think I said, but I am not sure that you realize that what you heard is not what I meant.” Some are too poor to pay attention. I have so many ideas I just do not have the technical skills to implement them, much less the funding at this time. I am wondering about creating an electromagnet to replace the neodymium magnets used in guitar coils, etc. It could have variable voltage, etc. Just wondering what differences it would make.

Very good circuit. Some of the best compressors use a combination of solid state compression and LED compression. The LED type is averaging and is slow while the SS portion is very fast and instantaneous. But you have a gpod example of a slow averaging LED compressor

I recently bought a Vyez system that I’ve been trying to increase the driver strength on. It’s pretty weak. The resistance is around 6.5 ohm. I was thinking of trying to add some wraps to the existing windings. The part that I was hoping to get some input on is the physical style of this driver in particular. The design is more of a parallel “hot rail” style. The 3 coils are wired in parallel, not series. I haven’t seen this style discussed. Can you shed any advice?
