[@lovescarguitar]

Do you think this is better for hard or soft rock?

[@le_fancy_squid]

[@UrgentDrive]

Probably the prettiest builds so far. They do look amazing. You've done a fantastic job on these.

[@giambibollareal]

If not the prettiest, it looks the most difficult, an extraordinary piece of cratfmanship

[@OliverKrystal]

The issue is from the dimmer, which is likely using PWM or pulse width modulation. Using a potentiometer to limit current would give you the results you're looking for without the feedback. I figured this out when I tried to make a tremelo pedal using a led/ldr/arduino arrangement.

[@silverXnoise]

^^ 100% correct. You could also implement a power supply pedal, maybe using a slimline pedal case so it can be stuck to a pedalboard without taking up much room, that injects the DC power using a single patch cable with a stereo phono plug, using one channel for the LED’s voltage, and the other for the signal. That way you just have one jack and one cable, plus you could add a battery pack in the pedal, and maybe a knob for selectable dimming levels via linear regulator to avoid the PWM noise. It could technically be achieved with a standard mono cable (this was my first idea), it would just use a capacitor to remove the DC after the LED’s tap off, however that would leave open the possibility of someone coming along and plugging it into a regular guitar and frying their pickups. Using a stereo phone plug provides an extra isolated tap, but still leaves it mostly standard. I think the guitar could even still work with a traditional mono cable/signal chain when you don’t need/want the lights.

[@killsalot78]

he should go full send, build a guitar with a 48v phantom power mic jack, but only use the phantom for lighting the LEDs.

[@seanedwards773]

A constant current power supply could also work. But definitely avoid PWM, which is usually the cheapest way of doing the brightness control.

[@lucemiserlohn]

A potentiometer playing limiting resistor for so many LEDs is going to die pretty quickly. What he is looking for is an adjustable constant voltage source, which would require an opamp and a power transistor. Usually, pots are rated at 1/8 Watts, and running lots of current through them is going to quickly boil off the carbon track that the wiper rides on. That many LEDs are going to draw a couple hundred mAs, which at 12V supply voltage is easily going to be much more than the pot is rated for.

[@lucemiserlohn]

@@seanedwards773 Constant current is going to be difficult because you cannot guarantee that all LEDs will behave equally, and thus some will draw more current than others (those LEDs are all in parallel - CC would be the better method if they were in series) - driving them with constant voltage is actually easier (but you need current limiting as well). PWM can be done also, but you need to drive the switching frequency up way outside of the audio range and introduce low pass filtering in the signal path. The main issue with cheap LED drivers is that the switching frequency is too low.

@@sireffortlessgarbage7922 did you show the judge? I bet he owns a PRS.

[@jayjayaye]

I feel like this vid is such a solid example of the evolution in someone's art thought and planning processes. Maybe this is a wild assumption, but if you had the idea "stone guitar" earlier on in your experimentation, I think it would have been like the salt guitar. Forging ahead with a material and it comes out just heavy as hell, but here it is! It materialized! And that stage of figuring out your art is important. Just plowing through and *doing the art*. Then we get to this. There was so much focus in this video-from jump, from the very first stages-on planning for actual usability, caution about the weight based on the material. Amendments to style at every step based on what you've learned and experienced with other materials and processes that have made the final pieces unwieldy or not-quite-right. And you guys firmly nailed it!! You may intimately know any flaws and shortcomings from having your hands on the process, but it literally gets more and more impossible for us, as viewers and observers of your art, to see those from the outside. It just looks and sounds drop-dead gorgeous. Thank you for another incredible (and inspiring) video.

[@JoeTheGuitarGuy]

It’s always a good day when Burls Art uploads a video.

[@NateSmith87]

I've been around guitars and other instruments damn near all my life; custom drums, guitars..but I've never seen a custom guitar like this! Crazy!!!

[@dacomputernerd4096]

LEDs tend not to go for actually dimming since the brightness is nonlinear, and instead dim via PWM. This means that instead of actually dimming to 50% brightness, they just turn on and off really fast so they are only on 50% of the time. This switching created the feedback you heard. Then it makes sense that making it brighter decreased the feedback since it would switch less regularly (probably smaller low-frequency components, so less audible feedback), and full brightness stopped it. Less than 50% may have decreased it as well. While fully on or fully off, it stops switching so there is no extra signal to pick up. Given the high frequency, you may have been able to clear it with a low pass filter, but that would also affect the tone of the guitar, emphasizing the lows and reducing the highs. Of course, just setting them to full works too. Perhaps you could also find dimming LEDs with a higher switching speed so the feedback isn't audible.

[@jasonsapp792]

I watch all your builds and most of the time I like them and appreciate your process.... These two are just something above your other builds .... Amazing

[@Blackenedin92]

Killing in the Name at the end is just icing on the cake

[@pikashroom1]

these might be my favorite guitars you've made. I've been watching since your first one and I'm always stoked to see what you come up with next!

[@my31and37]

Wow..Is it just me or is the one of the best sounding guitars yet?

[@1man1guitarletsgo]

I thought the tone was pretty good too. Shall we start a debate on which _stone_ is best for making guitars?

[@Dm3qXY]

when we listen with our eyes, we can be fooled, after all, that's part of the reason for the LEDs :) , however, they don't sound bad, they sure have their place for usability.

[@johnb2602]

Especially the clean tones - crystal clear.

[@BarronVonSchnoot]

Just you

[@kianr2200]

these builds only get better and better. super cool to see how far you've come. great ideas and executions, learning more with every project

[@jimcoppa6946]

You are the best I know you only have so much time but I really enjoy every project that you partake in and you're the best at what you do please keep these videos coming I enjoy them very much thank you so much and God bless you

[@DommoDommo]

These are sick you should do the same design but with a lavalamp inside hahaha

[@djmikeylove]

That would be tuff

[@oggy.6]

The microwave location was one of the best plot twists i've seen in a while

[@FunnyHaHa420]

It would be interesting to try switching out the LED strips with a light emitting polymer sheet. It could be adhered directly to the top instead of the diffuser sheet. The light would be evenly distributed and it might help with the feedback.

[@quinnobi42]

Very pretty guitars. The LED feedback issue would be solved by using DC voltage control for the brightness instead of the cheap PWM dimmer control. That would be one advantage to using battery power for the LEDs. Assuming you used a pot to add resistance to the circuit to dim them, batteries would not produce any sort of EMF noise which could be picked up by the pickups.

[@pluke63]

In these last 10 years or so I have seen virtually every single guitar build on KZbin, so it’s unlikely I see something that amazes me. However, this build definitely does. Jawdroppimg masterpiece, hats off, you are the Master.

[@cliftongardner4367]

Every time I think you can’t make a more beautiful guitar you go and do something insane like this. Incredible.

[@eleventhoperator]

Your videos are both really relaxing to watch but also incredibly fascinating - so much more goes into making the guitars you build than many other luthiers!

[@SignumIgnitum]

I enjoy the leveling up across these videos. I remember watching the original colored pencil video and thinking "That's cool, doesn't look too hard, maybe I could do that." Now I watch these and think "Man there's no way I could do that"

[@TheOneCleanHippy]

Stunning build as ever! You might be the most creative of all the guitar builders on KZbin.

[@snozking]

they turned out really good

[@cheesey4937]

This is crazy! I love your videos, i was really inspired by the infinity guitar you made as well, and have started making one.

[@Imabassplayer2]

Stunning, truly stunning guitars. I would probably say you best guitars yet. Fantastic job and always well worth the wait.

[@Bleats_Sinodai]

5:48 That's a trapezoid, not a pyramid. Also, the "feedback" from the LEDs dimming is because they're controlled by PWM (pulse width modulation), which basically blinks them really fast to control brightness, and that process generated frequencies in the audio range that get picked up by the pickups. You need to isolate your circuirtry in a faraday cage (aka conductive box) to eliminate this feedback, or at the very least, use shielded wring everywhere and surround only the pickups in a conductive, grounded box.

[@FatherWave]

its a pyramid

[@sireffortlessgarbage7922]

Well yeah, he said a “bit of a pyramid design”

[@erthboy47]

A trapezoid is a descriptor of a 2 dimensional quadrilateral with only two parallel sides and (usually) two sets of congruent angles. Trapezoid only exists as a cross section of a 3d object. Burl's shape was a truncated rectangular pyramid.

[@keiz_]

If you ever use LEDs in a build again, highly recommend checking out COB LED strips. They have way more LEDs that are super narrow, and have a layer covering them, and are so all close together it looks like a single glowing strip instead of having gaps/the individual LED look. I've used them in a couple projects of mine, and much prefer them to standard LED strips now.

[@internalscreech]

I really look forward to the wild builds you do with different materials, and this is why. These are absolutely gorgeous! Brilliant work as always, keep doing what you're doing

[@Bills_Place]

[@FuzzImp]

You never disappoint! I like that you highlight crucial details and drawbacks or fails on design but now you’re getting so experienced there’s less of those with each video. Big fan and love what you do. You pack months of trial and error and brainstorming and frustration and execution into these tight videos 😮

Stunning! Brilliant idea! Great choice doing two.

[@BlueSOF]

It’s always a nice surprise to see a Burls Art video show up in my feed. As others have mentioned, that noise from the LEDs and dimmer are from the PCM dimmer. Two possible solutions are to find a supply/dimmer with a switching frequency far above the audio spectrum, or put a filter on the LED’s power jack. It might be as simple as adding a capacitor across the positive and negative leads and an inductor in series with the LEDs.

[@00TheRealTC]

This is one of the sickest builds(x2) yet, Burls. They're things of beauty, for sure. I really like the use of the LEDs with the translucent stone. Thanks for sharing this with us. Keep the builds coming!
