Dude. Usually, your experiments are the crazy thoughts that go through my head, but I'm too lazy to actually do. This time, the idea is something that fluttered through my head, but hadn't even formulated into an idea. I just assumed there would be crazy hum. Anyways, props man. Well done.

Thank you for watching and taking the time to write a kind comment SMarkelet. Yes, this is an idea I had a long time ago but was too lazy to try myself but when Erick asked about it I knew it was time to give it a go. I was surprised the hum wasnt worse than it was. I think if I would have plugged it into one of the cheaper amps I have... it would've sounded like a wasp.

@@heavymetalATCI've got an idea I've been dreading trying to create, if you want to put the effort required into it, that's a big if but I've already subscribed so I'll see if you take up the challenge. It will be a pain in the ass, BTW, there is also a question I haven't answered via experiment yet that will affect one aspect of the design and if ineffective only makes it that much more of a pain in the ass to build. The question to be answered is what the result would be if the coil was oriented from right to left as opposed to vertical. Obviously a coil running the full length of the string spread oriented in this way would very much suck if it worked for any strings other than top and bottom E strings. Rather than a continuous coil, it would be many tiny coils with gaps between one another, basically like flat coils where the wire wraps around itself to form a one wire diameter length coil, or, as another way of describing the same thing, the Hypnosis cartoon graphic, a flat swirled coil. The purpose of the design was to see if a pickup can be design to pickup the back & forth motion of the string strong, as opposed to a normal pickup where the back and forth motion of the string adds very little amplitude, most of the amplitude comes from the up and down motion of the string as it vibrates towards and away from the coil. So, into the pickup design. First of all, the intention is to have individual "pickups"(single pole pickup) per each string. So only one pole has to be built to test the idea. This pole though, will be the pain in the ass, regardless of coil orientation but if the side to side motion of the string can't be picked up it'll just be that much worse. If the coils can be oriented left to right: Using the i's of a right sized transformer(or making the right size), to construct around a one inch length poll square/rectangle pole by stacking the silicone steel i's together BUT between each two i's is a flat swirled around coil, ideally only one wire diameter in length, as described above, covering as much of the steel sheet as possible with as tight of a "swirl wrap" as possible. The end goal working out to having square ends. Winding up with a single pole piece that is layered with a swirled coil between each slice of silicone steel. And if this weren't a high enough inductance, or just for extra amplitude, then wrapping a coil around that pole the normal way but, of course, the coil only going around that one pole. If that coil orientation doesn't work, or work good enough to be worthy of using, then the same idea only the slices of silicone steel are little squares and the pickup pole built up vertically with the same technique. - all the seperate swil coils would be wired in series, and if additional coil needed around the pole, once again in series. The point of the design being to have individual pole piece pickups with high enough inductance to be able to fit them side by side in one pickup slot(not having to have them staggered). All the single pole pickups also wired in series to create one pickup that fits in a typical strat single coil pickup slot. And the point of this design would be, for starters just to see how it would sound, but more importantly to have EQ adjustments on the individual poles, thus the ability to EQ each string separately(which would be a pickup with a shitload of wires because there would have to be output and input wires for each pole, to run through the EQ circuit after each pickup but still connecting all of the poles in series. Wire comes out from SPP(single pole pickup), goes thru EQ circuit, goes back to SPP, wires series to next SPP. The ridiculous amount of controls were going to be made to fit if it would work good enough to be worth doing. While in the original idea all 6 poles would need to be built to link in series with enough inductance, to pick up enough signal, from watching your U shaped flat copper coil pickup with a transformer used to adjust the impedance would work to be able to test a one-pole version. Being it would be such a pain in the ass, the biggest reason for why I haven't tried it yet, I can deDefinitely understand if you pass this one up 😢 😂 Oh yeah, and a tiny strong magnet on the bottom of each pole.
@gregglyne7886 ай бұрын
My understanding is that the difference in tone between various types of pickup magnets has to do with the inductance rather than the magnet strength. Magnet strength seems effect sustain more to my ears (assuming pickup height remains the same).

I've been trying to figure this out for some time now and came to conclusion that it is not only a combination of pickup coil resistance and magnet strength, but also a pickup construction. I had a cheap invader style neck humbucker of very muddy sound, took out ceramic magnet and replaced pole pieces with alnico 5 rods. Result: Nice, soft, bright humbucker, also with pleasant single coil split. The more resistance on pickup coil, the more mids. Experiment with a single coil pickup by attaching much stronger ceramic magnet made it sound almost full as humbucker with more highs. So, looking for your own sound might not look as simple as just changing magnet strength. It will be a balance between coil, magnet and overall pickup construction. Thanks for the video.

With G&L's Mfd's and the extra magnets that some Gretch pickups use, I would think the subject of increased magnetic fields and their affects on tone would be fairly clear. There is a balance of sorts in play though. I don't think overmagnatizing an overwound pup would be as desirable, unless wild distortion is the goal.

Thank you so much for watching Troy. Yes the general guitar community doesn't have much of a debate on the subject however all the experiments I have done on this channel have proven to be the exact opposite of the basically accepted and understood consensus. I dont know why this is? However if you google it or ask in a guitar forum or read on a pickup website: What effect does a stronger magnet have on a guitar pickup? The answer will be "brighter and harsher" I haven't found this to be the case at all. Neodymium magnets are super boomy and bassy not pure treble or ice-pick highs. The balance you mentioned is the key! The info I have gained from personal experiments has brought me to that exact conclusion. Higher wind counts with a weaker Alnico magnet will give you that vintage chuggy bell sparkle and Lower wind counts with a strong Neodymium magnet will result in a super honest and revealing full range high fidelity sound. Swap those specs and you will get a harsh twinkly ice pick or a compressed muddy dull thing. I just wonder why all the info and the answer you get if you ask the general "guitar dude" is backwards? Thanks again for the kind comment Troy I am so glad you enjoyed the video.

Thank you for watching drum crazy as well as for this great information. Yes I don't know much at all about magnetic circuits or flux vectors. Ill definitely look into that. I do however know about metals. I actually went to school for that, I worked as a metal worker, welder, and machine engineer/fabricator for many years. I can assure you that the metal plate was ferrous it appears to be some type of coated mild steel. you can pick it up with a magnet. I have also learned quite a bit about guitar pickups over the last few years through all the builds and experiments on this channel as well. I have actually used non-ferrous back plates such as copper in the past for desired effects. It seems the introduction of a non-ferrous metal such as copper or aluminum into that magnetic flux slows the eddy currents and reduces the resonant peak of induction in the pickup. Basically if you want a fatter bassier pickup: slap a thick copper plate on the back. I can say I was well pleased with this experiment though, it worked great. The results I got in this video were perfectly in line with my previous observations. It seems that though the general consensus in the guitar community is that more magnet equals a brighter sound I have found the opposite to be the case and have built some very good pickups around this idea using neodymium magnets non-ferrous back plates and lower than average wind counts.
@drumcrazy58662 жыл бұрын
B and H both in magnetism matter. Most of those baseplates are copper plated steel. They work as concentrators for flux density (H) and alter coercivity of the magnetic assembly (permanent magnets and ferrous metals combined) so you'll generally see higher inductance and greater resistance to change in gauss levels in the magnets with other ferrous metals attached. Increase in flux density generally increases power (dyne/Weber) that drives the output higher and the resonant peak with it.

@Drunken_Hamster10 ай бұрын
I think I'm starting to understand. Magnet strength affects inductance, which is one part of output. It also seems to add bass and mids a touch more than it adds volume to highs. The DC resistance is a part of the output equation but also affects how much the pickup will naturally drive the amp. This is why higher ohm pickups are darker and grittier. So... Technically speaking, the best thing to do is use the strongest magnets, and the least amount of the thickest wire you can get away with for your desired resistance, that way you get all the highs, all the lows, decent output, and you dial in your drive/grit via the resistance/turns.

You got it down like down-down, great accurate thinking. More turns does also act as a physical capacitor to darken the sound it gets "sticky" to the electrons with all that wire bunched up where they can interact. when you say "technically speaking" you are exactly right. that would be the kick @ss hi-fi sounding pickup from hell. Its the whole idea behind my neodymium p90 build. lower winds higher magnet power. but... we as humans some reason nostalgia harmonic complexity etc I still love a relative high wind low magnet power strat coil making hendrix chime sounds? A perfect speaker is what youd think you want too but the most common guitar speakers are all mids and not hi-fi at all cause the sound coming out of the output jack of the cranked tube amp is not actually that awesome marshall stack sound its pure fizzz and horrible hissing screaming harmonics the "BAD" alnico and construction paper speakers are filtering it out to sound sweet. the whole deal is pretty crazy really but you are totally on the pulse of it and you get it with the pickups 100%

One thing I've noticed is that if they're close to the string they can introduce a detuning effect which can range from pleasant to severely horrible. I mostly play around the fifth fret, and so have my pickup heights adjusted so the magnets sound good there, and they're not too bad at the 12th fret, but going beyond that the detuning becomes really bad, to the point that the horizontal and vertical vibration modes of the strings produce pitches that are almost a semitone apart.

I'd second the suggestion of trying to get an understanding of magnetic circuits. When a guitar string gets closer to or further from a normal pickip, it varies how much of the "circuit" will fall inside the coil versus outside. The electromagnets you were using are designed to keep most of the flux very near the magnet, which improves the performance for picking up nails, but degrades it for the purpose you're after here. I think a better approach might be to use a humbucker, but replace the bar magnet with a bar of steel with many turns of magnet wire wrapped around it. If your resistance is 8 ohms and you drive it with 1.5 volts, it should consume about 0.16 amps, and dissipate about 0.25 watts. Enough to get slightly warm, but not excessively hot. Field strength might not be huge, but having the magnet in the humbucker's magnetic circuit connecting the pole pieces on the two sides should mean the magnetic field has a useful effect.

My intuition says it will be higher output, so i'm starting to dream up some pretty dubious pickup designs.

Interesting experiment. Now you need to remove the magnetic string pull from the equation. Stronger magnets pull the string downward and remove the “meat” out of tone. I suppose you could have another magnet over the strings that would pull them back up. Or maybe a split humbucker with one coil over the strings and the other under the strings. It’ll be a bitch to get the windings and magnetic poles right but science beckons.

Thank you for watching and taking the time to comment Alaric. That is a great comment and you are always an awesome thinker. That would totally be the case but... I removed all that stuff and blocked the trem with a wooden block before I ever did the first video with this guitar. I didnt want the springs to affect the results in any way. I know some people stuff foam or paper around the springs but in my personal player Strats I like to use 4 or 5 springs even though I don't use the tremolo bar it seems to add some kind of reverb or resonance to the sound. It may just be in my head due to the fact that I can feel it against my body but I could swear I can hear it. Either way yeah, I removed all that in this guitar. Once again though, very intelligent comment Alaric.

Thanks for watching and taking the time to write a comment Vincent. I saw this comment last week and ive put some thought into it and with the mega output im getting at 24 volts into the magnets its something like 200 newtons so like 22.5 lbs of gauss so it would probably still overdrive my DI box. I was using a clean solid state mini PA for keyboards in the video and it usually doesn't get dirty at all even with humbuckers. It was just a whole lot of juice. This would be worth trying and its a good suggestion but as well I dont know that it would be good for my YT algorithm to post as a full video. I really should start using a spare channel to post short videos and small experiments to answer requests like this because that is a very good suggestion. I'll put this in my notes and use it as a consideration for starting up a second channel.

If you don't have an interface you can get some for cheap. I recommand. Berhinger (cheap) & Audient (value). I suggest to record in Reaper. -You can level match with a limiter or compressor. -Show eq graphs. -Get some great tone quick with amp sims. Keep up the good work.

That is a good idea and a cool project! One thing (not a negative) is the decrease in sustain as the magnet power increased?!?! Did you notice any?? I recently subscibed to your channel! Your videos are awesome!
@heavymetalATC2 жыл бұрын
Thank you for watching Brian. That is a good point I really should have done a sustain test. I can tell you though that from my experiments in the past an even stronger magnet than this like N94 Neodymium behind the pickup doesn't really kill the sustain... Its just too far away to really pull on the strings. Magnets seem to lose power over distance very quickly its exponential. Though I can say from personal experience if you get Alnico slugs too close to the strings, this happened to me on a strat, you'll get a warble/wobble unpleasant chorus sound and the sustain will be diminished somewhat. This is what has kept me from building any Neodymium pole pickups. They would pull the strings way too much maybe to the point of sticking but a bar or even 2 bars and 8 buttons behind the pickup doesn't seem to kill sustain at all. Thanks again for the interest in the channel as well as taking the time to write such a thoughtful and kind comment.

These 2 magnets - can they be used like a single string pickup? Would they make strong signal?
@casanovafunkenstein5090 Жыл бұрын
Edit: Hi there. Just came to the realisation that what I said was a bit silly. The ferrous material in the electromagnets isn't magnetic without a current, but if you stick a bar magnet to directly to them they'll probably work as pole pieces (depending on the metal. If it's steel in there it'll work) and the same inductance principles would apply as with a more conventional design, though the way that the electromagnet is designed may mean that there's something in there to ensure that the core doesn't end up permanently magnetised when the current is turned off. Took me a while to realise that I wasn't looking at this from the right perspective. Not really, as the core isn't magnetised unless you run a current across the wire. You'd need a very robust power supply in order to get enough current across six of these to magnetise them and you'd also need to have separate winds of wire for each string wrapped around the magnets to produce a signal. If you wanted to make a hexaphonic pickup there would be easier solutions, such as creating a bobbin where there are several sections with dividers along its length. You could then wind the coils so that the direction of the winds runs in the same plane as the strings. This bobbin could be 3D printed, but there's nothing to prevent you taking a cylindrical piece of steel (with a magnet in direct contact with it to make it into a long pole piece) and adding washers to it at regularly spaced intervals. You could then use a power drill to turn it while you wind the coils individually (make sure that you have a means to keep the lead wires from getting wrapped up and lost inside the pickup. Tape them all together and make sure that they're as far away from the coil you're winding as possible until you're ready to solder them. The signal comes from the current induced within the coil, so having only the one magnetic element is not an issue unless you want to go crazy trying to make a humbucking version. Simplest way to achieve that is probably build two half-size versions with opposite polarity directions for the pickup magnet (though you could maybe solder the leads so that each coil is out of phase with its neighbours. Would probably sound weird through an amp but if you're going to be converting each monophonic pickup into a midi signal anyway it would probably improve the design by reducing cross-talk and giving clearer signal for the converter to interpret. This is part of why a lot of MIDI pickups use piezoelectric saddles: much easier to isolate and it doesn't really matter if they sound like regular pickups for that application. Outside of Roland and a couple of more experimental designs made by very small shops, where it's probably a passion project put together by a guy who makes them at home because they have a day job, it's really rare to see a hexaphonic pickup made with magnets, though the company that makes those little submarine pickups has put one out with dip switches to turn parts of the pickup on and off. That one doesn't allow for each string to be processed separately though, so it's definitely not a viable option for converting a guitar into a midi controller).

Thank you for watching Extra crispy. That is exactly what I witnessed and exactly what I thought I would considering my previous experiments. The thing is... This is exactly the opposite of what you will find if you look this up on google. It will say a stronger magnet equals brighter and harsher sound... not according to my experiments? It tends to increase bass and the only harshness it imparts is from over-driving the input amp as you stated. Its a magnet conspiracy I tell you Hahaha Really though I just dont understand why all available info on this subject is the complete opposite of what I have personally witnessed time and time again.

@@heavymetalATC I made a couple pairs of split/z coil neo magnet pickups. they are wooden bobbin pickups similar to what you've made. One set sounds good. the second set i wound hotter, and for some reason it sounds sort of honky/ cocked wah like especially with distortion. I've reversed the magnets and it swapped leads wiring the coils, and even when set up for proper humbucking they still sound weird. i think my problem is that i used some old 8/32 truss head screws as my pole pieces, and the gauss is very weak at the string side of the pickup. i think if i had proper thick pole pieces the pull on the strings would be stronger and give me a proper full sound. It was just an experiment, so it's not a failure as long as i learn something from it.

@@heavymetalATC Also i have an idea that you might want to try. I actually built one, but i severely underwound the pickup, so it was weak, and haven't been able to get the time to try it again. I was trying to make a neo dymium magnet pickup that worked with the same concept as a filter Tron. the filter Tron has a powerful magnetic and very weak coils. i wound two coils with i think about 2500 winds of 42 ga wire. I sandwiched an n95 bar magnet between the two coils so that the magnet laid on its side with north facing one coil and south facing the other. i thought that since the magnet was going to be much closer to the strings that the magnetic pull would make up for the low wind coils and give it a decent output but clear tone. They ended up being weak. I think the same construction with the typical 500ish winds per coil like a normal humbucker might make for a decent output pickup. i can send you a pic of it and an exploded drawing if my written description does explain it well enough. Sandwiching a magnet between the coils of your super humbucker might be interesting as well.
@casanovafunkenstein5090 Жыл бұрын
Had a bit of a brainwave looking at someone showing off a Peter Green style mod (reversing the polarity of the magnet and putting them out of phase) and thought about using an electromagnet with the ability to swap the direction of the current running through it in order to swap the polarity of the pickup, so I ended up back here 😅 Edit: I could see something interesting being done with a couple of small, low power electromagnets at either end of a ferrous cylinder, with the wire for the pickup wrapped around the cylinder, so you get a magnetic field that runs horizontally. The other pickup could just have regular magnets in place of the electromagnets. In theory at least this should magnetise the cylinder along its length. I may be completely wrong about how this works because I have no background in electrical engineering but it seems plausible given my limited knowledge on the subject.

Thank you for watching Ryan. Absolutely but that is a much different animal all together. Active pickups are just normal passive pickups (usually low output) with a built in pre-amp circuit. In short its simply just a boost pedal inside the guitar instead of on the floor. This is an actual adjustable strength electromagnet in place of the permanent magnet found in normal pickups. Its like having every magnet type from weak Alnico through the strongest Neodymium at the twist of a knob.
