DIY "Tube" Distortion - High Voltage Neon Drive Pedal

Gas discharge tubes such as neon lamps conduct non-linearly, and have some other really cool conduction properties - like negative resistance and hysteresis loops, for instance. This project uses a neon lamp as the main distortion element in a drive/fuzz pedal, for some pretty unique tones and behavior.
This is also a higher-voltage version of my "blank slate" distortion/fuzz/overdrive pedal and the high voltage opens new possibilities such as stacking sounds on top of each other by putting components in series.

Oh man you nailed the 00s grunge tone without even trying hell yeah. Might have to build one of these into my amp project once parts start arriving- I’m using one of those “Tube Fever” kits off Ali in combination with a couple op amps and some clipping diodes to build a low wattage practice amp that still has some of the features from larger amps.

GE published a 500 page manual on their little NE-2 bulbs with tons of circuits. They need light (or radiation) to work, which is why the orange lights on power strip bars flicker in a dark room. The amount of ambient light would probably change your distortion tone!

I have a Nixie tube power supply I was thinking of using for the high voltage in a project like this. How would you go about that? I suppose I'll have to control the signal with a transistor? Conversely I could try to find a transformer but I'm not sure where to look for the right specs.

The point of using a transformer is to avoid the need for a high voltage power supply. If you just want to do it with high voltage that's a completely different circuit.

@Psychotenuse 2 года назад

I'm not sure what you mean by stacked. The neon lamp is not a valve and it has no amplification capabilities. To make this transformerless you would need a DC rail at 90 volts or higher.

@paigdyll 2 года назад

@@Psychotenuse stacked like op amps in a pedal

@Psychotenuse 2 года назад

Your questions seem based on the idea that a neon lamp is an amplifier like a valve or transistor or op-amp. It is not. It is a passive nonlinear component like a diode.

@Centar1964 3 года назад

An adjustable dc bias voltage on the neon would make this soooo much better...

@Psychotenuse 3 года назад

Ah, I see what you mean... It would require a completely different approach, though, since the whole point of using a transformer in this way is to avoid the need for a high voltage DC rail. I suppose, though, that a DC offset of up to 9 volts (or whatever the pedal supply is) would be easy to implement. That might not have much effect on the sound. As it is, I suppose asymmetry could be introduced using zeners or something in series with the neon.

@Centar1964 3 года назад

@@Psychotenuse You could either use a small dc to dc converter module or a small transformer(based pwr supply) to isolate from the mains...run that in series with the neon transformer you are using....

@Centar1964 3 года назад

Also here is a thought...currently your circuit shunts the high voltage audio signal to ground through the neon...what if you took the "conducting part" of the neon only as the output audio signal...clipping the low volume (severe crossover distortion) as opposed to clipping the high part of the signal(square waving)....this has been an idea floating around in my head for a while but haven't tried to develop it yet...

@Psychotenuse 3 года назад

@@Centar1964 Yes, there are ways, of course, to make a high voltage DC rail. The point of using the transformer is that it eliminates the need for one. The transformer would be unnecessary If a high voltage DC rail was available, since then the obvious way to do things would be simply to use a high voltage amplifier. If by "conducting part" you mean the current through the lamp, this can be done more or less simply by connecting the output across the drop resistor instead of across the lamp. This would result again in a "squelch" effect, i.e. distortion on the bottom of the wave rather than the top, with an inherent gating effect and a different sound, distinct from overdrive, which cleans up as you play louder instead of getting dirtier as you play louder. One thing I want to do if I ever build a stage-ready version of something like this is to have three terminals instead of two, such that the drop resistor and "clipping" element could both be swapped. This would allow changing the effect from drive to squelch by simply swapping the two components, and would allow cool combinations of the two as well.

@Centar1964 3 года назад

@@Psychotenuse Ya the drop resister is what I was thinking...should be an interesting sound, never heard it before.

@socialistsuccubus822 Год назад

is it possible to put more than one lamp in series or parallel? You should put something like an LM386 in front of the transformer if that's possible so there's more gain o.o the transformer might be adding distortion in a way too

@Psychotenuse Год назад

Putting multiple lamps in series will give you much less, if any, distortion. Putting them in parallel could be interesting. The gain before the transformer is not currently limited by the choice of chip, but rather by the supply rail, which sets the headroom.

@Psychotenuse 2 года назад

So I came up with a network like this imgur.com/a/HVgTLwY looking for something whose I-V curve has negative curvature, i.e. the static effective resistance increases with voltage. R1 here should be 10 - 100 times bigger than R2. When the voltage is lower than the threshold voltage, most of the current flows through R2. When the voltage is higher than the threshold voltage, much of the current flows through R1. Two of these networks connected anti-parallel gives the squelch network I showed. As for the clipping part I don't actually remember exactly what it was but it's diode-resistor series pairs connected in parallel.

@paradiselost9946 10 месяцев назад

interesting. theres a minute capacitance when its not conducting... picofarads... still sucks some of the top end out. remember, it STRIKES at ~90V... but it CONDUCTS at much lower voltages once it strikes. about 20... so you clip the wave when it peaks out, and then... theres this interesting effect... it will always pull the waveform back down to the conduction voltage, only conducting whilst enough current exists to maintain ionisation. how much power is the amplifier delivering, resistance, frequency, etc... if the waveform reverses before ionisation decays... it will continue to conduct. if it doesnt reverse fast enough, then the neon will stop conducting and only strike again as it hits that 90v peak again... so the deacy characteristics as the amplitude and frequency and ionisation /deionisation rates all interact are particularly interesting... would have loved to see some scope traces? im assuming high amplitude high frequency signals will tend to "reverse conduct" far more... now i gotta throw this into a tube somewhere... this is only one of literally HUNDREDS of ways of messing with this concept... thought of before but never bothered trying?

@leohobbleohobb3781 Год назад

When u using a led bulb you are essetialy using a switch mode supply like in phone chargers etc. Every" led bulb have main swith mode supply in it, and when made with cheap components to little cooling for leds and the electrlytic cap in the psu that are in the socket of led bulb they fail way to fast. Only quality brands last, They to could do a better job, not a design problem at all. Truth are that led bulbs create way more e waste and polution that the old wolfram bulbs that was planned to fail around 2000 hours. To make a led bulb better in all aspects top compnent must be used and a low temp as possible for elektronics and leds when driven is needed. a led can last 50 000 hour if the see true material on the led/leds does not dry up do to heat and the inner jucktion get ecposed to air moist and go bad.

You need either digital processing or mechanical movement to get any kind of frequency-independent delay. There are some "analog delay" pedals but they are sort of 'half-digital' in that they use a discretized time axis. It would probably be possible to build a reverb pedal using a popular microcontroller like an Arduino. Maybe something I try someday but I'll have to learn how xP

if those are high voltage leads... how are you now getting zapped handling them like their turned off?

@Psychotenuse 2 года назад

Hahaha. Well, first of all, I don't recommend you emulate my behavior in the video. To answer your question, though, I am getting zapped a bit sometimes, but it's not too bad because my hands are dry and I'm holding the leads fairly lightly. I have also tried - for science - licking my fingers and grabbing the leads tighter, and yeah that definitely gave me a good little tingle in my nerves. There are several reasons it's not particularly dangerous. The high voltage side on the transformer is effectively isolated from mains, so I'm not going to have currents running through my body to ground. As long as I only touch the contacts with one hand any currents will be only in that hand. Then the neon bulb itself clamps the voltage to its nominal 90V and the drop resistor limits current further... basically while I definitely don't advise imitating my stupid behavior, I've also definitely not built an electric chair here.

hello, very good video. The project is phenomenal. I only had three questions. 1-Can a direct current of 15 volts be used for the TDA 2030? 2-If the transformer is T1=1:24 (5volts/120volts) what would change from the schematic in googledrive? 3-at time 5:42 you used a led bulb, can any be used?

@Psychotenuse 2 года назад

Thanks for watching and commenting :) 1. Yes, the TDA2030 can be run off 15V. 2. That transformer should work fine. You'll be operating it a bit outside its voltage rating but probably not enough to damage it, particularly since you'll probably be way under the power rating. 3. The LED bulb is being used as a clipping element here, so clearly an incandescent bulb will not work. A fluorescent lamp might do something interesting, but I can't promise you it's not dangerous to try. Even among LED lamps, only the simpler ones will act as a clipping element. Some fancier LED lamps may have complicated driving circuitry in them, in which case you won't get the kind of result you see in the video.

It's a cool little experiment. I'm a firm believer semiconductors do it better than tubes, but there's also a lot involved to get the circuit there. The compression of the control grid in the tube plays a pillar role in it's most desired characteristics, and so does the limited bandwidth in comparison since they tend to cut off at about 10 Khz when used with guitar. *The last few days, I've used a pair of diodes in a feedback loop on a very simple high gain transistor amplifier, and I'm getting the dead on distortion texture of a tube, but it needs significant refinements with some RC networks and truly, more architecture to be truly useful. About 9 years ago, I pieced together some of my original designs and I had a sound dead onto a 5150 and a Mesa Dual rectifier, but 100% semiconductors. I had the definition of tubes, the saturation and texture of tube distortion, and just needed more gain to shred metal. I'm restarting that journey and this time, I will complete it! Your experiment taps into what I've long since necessary which is very high voltage distortion. Most of us want that zapping, zinging froth and glassy buzz of tubes without the price, and I'm ranting just to say, it can be done.

There’s a company called surprise sound lab that makes a pedal that uses semiconductors in a high voltage circuit that sounds pretty good.

Thanks for watching :) If you mean the schematic for the circuit, there's a link in the video description.

Works well as a fuzz pedal

@belduarteprojetomusical2214 3 года назад

Uow, fantastic! How many volts was the circuit powered?

@Psychotenuse 3 года назад

In the video it's running off a 12 volt adapter. It would probably work fine off 9 volts, though.

@error8418 2 года назад

Great idea! Reminds me of the Plasma Pedal by Gamechanger Audio.

@Psychotenuse 2 года назад

That was partly the inspiration, I'm sure! Thanks for watching :)

@sentient8653 3 года назад

I was looking at these on mouser a while back and wondered if you could use them for a VCF. This is cool too.

@Psychotenuse 3 года назад

Not immediately clear to me how you'd use it for a VCF but if you have a high voltage DC rail it is really easy to make an LFO with one of these (literally 3 components).

Really good project. What is the power supply voltage value that you are using? Is it 9v or greater?

@Psychotenuse Год назад

Glad you like it :) I was using 12v in the video, but it should work fine on 9V.

excellent idea, patent your idea. The other thing is that, if the more detailed project could be published? I don't understand the schematic and I don't know about engineering issues. Or Photos of Proyect.

Glad you liked it :) Not sure what you have in mind though about the more detailed project. What don't you understand about the schematic?

@havieralvarez2500 2 года назад

@@Psychotenuse it's okay. The detail of the triangle before the transformer in the schematic. What is that triangle?. What type of transformer does it use? I see that there is a source, maybe 9v. That's right?. And what potentiometers? How are the potentiometers connected?

@Psychotenuse 2 года назад

@@havieralvarez2500 What I show in the video is just a rough "block diagram" of sorts to give an idea of what is going on (the triangle represents an amplifier). The full schematic is linked in the description, as well as a parts list.

@treyyoung7096 2 года назад

Big fan of the channel and your projects! Is the step-up transformer in the audio path in this circuit? I'm new to electronics and still figuring out how to read schematics. If it is in the audio path, does the frequency response of the 1:20 transformer matter? Like do I need to find a 1:20 audio transformer or power transformer or does it matter? Thanks!

@Psychotenuse 2 года назад

Yes, the transformer is in the signal path. I'm sure it affects the tone, though I'm not sure how much. I'm just using a step down power transformer in reverse; I'm sure a specialized audio transformer would perform better though, if you have one.

@treyyoung7096 2 года назад

@@Psychotenuse thank you sir! I was curious mainly because I was having trouble finding any 1:20 audio transformers and was hoping a power transformer would do!

@paigdyll 2 года назад

You should try to make a boost style pedal from this

@Psychotenuse 2 года назад

That would essentially just be an op-amp boost.
