DIY Guitar Headphone Amp - plug type

[@jjhack3r]

I've never met anyone in person that does the type of things you and I do. It would be cool to have somebody to do a collaborative project with. The things you make are more useful and practical that anything "Great Scott" makes lol

[@man4consrobot]

I totally agree. Why isn’t there a place to learn and talk about these things? Discord server?

[@man4consrobot]

@@Psychotenuse would you be opposed to helping me out with this build?

[@Psychotenuse]

Not at all, if you mean help you troubleshoot, come up with mods etc. Write me at my business email

[@man4consrobot]

@@Psychotenuse you are the greatest

[@CuriousMotor]

Super cool sounding and unique!

[@Psychotenuse]

Well thanks, it's a super basic circuit :)

[@duartefernandes1667]

exactly what i was thinking of doing and now i know its possible thanks!

[@marccawood]

Frikkin cool! Nicely done!!

[@Psychotenuse]

Thanks!

[@alpesta]

You're goddamn genius! THX

[@Maax3dledesma]

Hola sirve para bajo electrico?

[@alteans]

Truly home made😁

[@gokhanozdemir9314]

You know, actually there is much more room in there. You can stick even more man.

[@RadityoPramAdi]

very nice, I'm gonna try make one!! Keep it up bro!!

[@Psychotenuse]

Thanks! Hope it works out for you :)

[@RadityoPramAdi]

btw, is the inverting input labeled -IN in the diagram? sorry, I'm a complete noob in electronics..

[@Psychotenuse]

Yes.

[@RadityoPramAdi]

Thnks!!

[@RobertSaxy]

F-ing brilliant

[@Psychotenuse]

Thank you!

[@HOPEX00]

What is the connection of potentiometer ?? Middle pin goes with the center of the mono jack ?? Or any other from two sides

[@tommysalacious1320]

Would it be possible to see how the components are connected minus the tape? Trying to replicate this on a breadboard. thanks

[@Psychotenuse]

There's a schematic linked in the description.

[@oscarfurno5000]

Hi, more than interesting project, were you based on any modification to the circuit or is it a design of yours? congratulations, I will try to do it this afternoon, I will use it on an acoustic guitar that already has a preamp

[@Psychotenuse]

It's a really basic inverting amplifier circuit, electronics 101 textbook type stuff... Good luck :)

[@Psychotenuse]

If you're using it with an acoustic guitar with a preamp, I would recommend you add a resistor to the input, to limit the current drawn from the preamp. Perhaps around 10K, but I would have to experiment a little to find the best value.

[@oscarfurno5000]

@@Psychotenuse thank you very much I will take it into account, without resistance could the TDA2030 be damaged or it could receive too much gain at the entrance and saturate?

[@AxV-0922]

Baiiyaaa.. I hope one day you can build your own factory.... Syaabas..

[@Psychotenuse]

Hahaha, perhaps xP

[@namannegi3629]

I hav build an amp using lm386, but it giviing distrorion or overdrivern signal, im going build this amp for clean channel, will this work with 9 v dc

[@Psychotenuse]

It should work fine on 9v. Just make sure you use appropriately rated capacitors.

[@prabhatbhandari]

I have no idea how to connect the guitar input. Where should the tip, ring, and sleeve be connected in the circuit? Could anyone help me with that? I understood the other parts in the circuit diagram but not that part.

[@Psychotenuse]

As you can see there is no "ring" contact on the audio jack I used. If you use one which has a ring contact, you can connect it to the sleeve contact.

[@Psychotenuse]

The outer circle is "sleeve", dot in the middle is "tip"

[@md.mesbaulhasanrashed6342]

how i could use 50K OHM VARIABLE POT RESISTOR POTENTIOMETER it has 3 leg(in, out, gnd) and in head phone output i need stereo out please advice me

[@Psychotenuse]

Typically, the middle terminal is the 'tap', so to use the potentiometer as a variable resistor simply ignore one of the side terminals.

[@Psychotenuse]

If you want the same thing in both ears, connect the "left" and "right" terminals on the headphone socket.

[@pratbrat3492]

since theres a virtual ground to create a split supply, shouldn't there be a small cap at the input of the amp to avoid getting any dc into the amp? or any dc through the coils of the pickups?

[@Psychotenuse]

Yes, you could certainly add more stuff, but I've kept it basic. Since your guitar pickup is basically a coupled inductor (think one coil of a transformer), it is unlikely to generate a persistent DC offset. And if there is an offset somehow - faulty active pickups perhaps - then that is still unlikely to fry your headphones because the output capacitor will block it. Worst case scenario you get some distortion.

[@wayneburnell4106]

Sir could you show me the wiring on the TRD 2030 and other remain wiring. So well you have made the diy. Wayne here

[@Psychotenuse]

You should be able to figure it out from the circuit diagram linked in the description...? Let me know if it's confusing somehow or if you have any questions :)

[@Invisible_15]

Did you use 100uf 50v capacitor ?

[@Psychotenuse]

The capacitor just needs to be rated to your battery voltage at least

[@emersonsrandomvideos248]

Can we use that for electric bass?

[@Psychotenuse]

Yeah, it should work fine for bass.

[@evannielson3028]

Is there a way where i can add more affects to it, like a volume potentiometer, and/or a treble potentiometer and effects like that?

[@Psychotenuse]

Well, the one in the circuit _is_ a volume potentiometer. A treble control could be made by putting a capacitor and variable resistor in parallel to ground from somewhere in the middle of the feedback loop.

[@Ghost_70026]

You sure it won't blow out my headphones speaker?

[@Psychotenuse]

From what I remember this amp was pretty quiet. In fact I have headphone guitar amps from Monoprice and Valeton and they are way louder and I'm more concerned about headphone damage with those.

[@rayapatipeeraiah7172]

Can you send the materials you used

[@Psychotenuse]

I'll link a list in the description. Check back in 1 or 2 days. Thanks for watching :)

[@lukaneco200]

lovely this project

[@strawbryzk6349]

Please step by step soldering part im newby electro

[@Psychotenuse]

I understand what you're saying, but such videos are much harder to make and not really feasible except for very simple circuits. I did one recently for a MOSFET preamp circuit build.

[@HOPEX00]

Bro can you please suggest me a capacitor instead of 100uf

[@Psychotenuse]

The higher the better, I would not go lower than about 10 microFarads

[@jetrotirona1911]

Hi ThePsycotenuse!I'm very interested in making this for me..however, I'm no expert in electronics, can you pls give me a list of all the components of this circuit? then I'll try to match it using the diagram. Thank you very much!

[@Psychotenuse]

Jetro Tirona I used 1 TDA2030 audio amplifier chip 2 10K resistors 1 sliding on/off switch (I actually used a two-way switch) 1 50K potentiometer ("breadboard" type) 1 male quarter inch (P38) audio connector 2 female 3.5mm audio connectors 1 100microFarad electrolytic capacitor 2 AAA cells Lots of multi-strand wire Good luck! :D

[@jetrotirona1911]

Thank you very much! I'm now trying to fit the pieces to my breadboard.. hope I can make it work :D I'm a new subscriber btw.. keep posting cool stuff!

[@jetrotirona1911]

It's working! :) (I'm using bass guitar) made it work on a bread board.. weird thing is only 1 headphone (left) is working.. I'm thinking this is because I used a mono headphone port.. I'll find a stereo and finalize this :D

[@Psychotenuse]

Jetro Tirona Yay! 😀 Yeah I'll get around to posting new stuff... I'm a student so most activity on this channel is during breaks etc. Thanks for subscribing!

[@walterpascual8068]

Can i use 9v for that?

[@Psychotenuse]

Yes, 9 volts should be fine as long as your capacitors are rated for that.

[@RoyyGreene]

Could i just use a 50k pot instead of the variable resistor?

[@RoyyGreene]

Found out i can, cheers for the vid

[@Psychotenuse]

Cheers :)

[@INFO_SELABX]

preset will die in a while ..small volume take via aliexpress

[@HOPEX00]

Bro what is the voltage of the capacitor????

[@Psychotenuse]

Lol well seeing as the circuit is powered off a 3V battery, any capacitor with a voltage rating above 3V should be fine xD

[@HOPEX00]

Please reply asap

Dont get that super glue and cotton on your skin. It burns bad. I know
