Cheapest Guitar Reverb? $2.33 AliExpress Reverb/Echo/Delay circuit board!

In this Action-Packed video, I wire up, demo and review what may very well be; The World's Cheapest Reverb Unit!

All kidding aside, this was a fun project, and if you're a musician on the cheap, like me, there is no shame in buying what you can, until you can buy something better! This is also a great project if you're interested in learning about electronics and want to try your hand at soldering.

The PT2399 IC can be purchased for even cheaper, and there are schematics/diagrams available online (via a quick google) if you're interested in wiring up a PCB or breadboard from scratch.

Thanks for watching. :)

Just got a second reverb board, will try to connect parallel. I also try with reverb and tremolo parallel, works very well and gives a wide range of nice effects. Tremolo I designed by myself and works great without ticking noise, I will make this design later available on YouTube with schematics and pcb layout for toner transfer.

I bought that board a few years back, but didn’t know about that mod to adjust the delay signal. Thanks for sharing!

A hint to all the users below. This device has a low impedance input. So when you go with your guitar in this device the signal of the guitar will be smaller and less high freq. It is nessecary to make a JFet input buffer at the input. Then it works very good.

I think that hiss is caused by trying to push a pt2399 into the 600ms range, Might be remedied with a specific type of POT. Might be some other stuff going as well but Im pretty sure thats one reason.

[madzpanda]

So at this point I bought a bunch of these, and made one with just it's original pot, and no buffer, and then I have a couple like you did with a buffer (and these people are right it helps, also pedalpcb has a really cheap non powered fet buffer pcb that's super easy to build). There is a few modifications you can do and some channel called robs mods also covered this. The idea was neat and lead me down a path of repurposing stuff for pedals. I'm making 3 or 4 different fuzzes based around a lm 386 chips you can buy on a pre-assembled board just like this but it's even cheaper than these karaoke echos. I also made a pedal out of an artec 5 distortion knob meant to be installed in guitars, a voice changer diy kit, and I made a lofi looper sampler. I also took a diy Haynes synth and added stuff around it and started making video mixers, and other weird things because one day I came across 3 videos and one of them is this one. I keep coming back hoping there is an update or something new to learn, and I can't blame you for having a life and not going back to this, but man I hope you do. I have 2 dsp effects things I bought off of ali I hoping someone makes a pedal out of and I can see that and make it work.

You made a very informative video, and it was unintentionally inspiring for me, and you seem like a chill man, who makes quality content. The quality of the video as far as picture quality and aesthetics are nice as well.

Price is now 2.56. That's an outrageous bait and switch.

Just kidding of course, this looks perfect for some mini diy synth projects, breadboard experiments, etc. Thanks

menos tiempo eleva la frecuencia de muestreo y con ello la resolución y fidelidad

[jackrussellbruce]

I wouldn't be so quick to judge this board as sounding because it is cheap, you'd be surprised how many pedals the PT2399 shows up in.

[noncesens]

Uuh I really liked your video, I could listen to you all day. You are explaining everything so calm and methodologically, this is how youtube videos should be and it is a welcomed contrast to other youtubers. It is really nice that you are showing variations of the different parameters and the quality of the recording is so good that we can hear it too. I also thought … huh someone likes to show us they can play guitar ;P

There are many guitar pedals based on the PT2399 … so it would be interesting if there are other boards which are not for karaoke that would make decent pedals. A buffered pedal would probably increase sound quality.

[nedstar]

I received my board yesterday and build today in a metal case, it works great. Now I will solve the problem of popping sound, will let it know after succeeded.

[nedstar]

Excellent, I order by aliexpress the same board a few weeks ago. Still waiting to receive, but as soon as I get it, I will try it out. By the way because the circuit is not shielded in a metal box you will always get some fuzz. Thanks very much for sharing.

[jameskayeartist]

you are cool as hell man! thanks for the demo

[Mi-cha-el-Edward-Lee]

Which part controls the repeats?; I will put a pot on that also.
High milliamps is clearer on this chip than a battery, but, I think the degradation sound warmer on a battery, on the 2399 type delays.
Also; I wanted to see how you removed that "surface mount"'resistor; because, it has no legs through the board:
Do I just heat the entire component?
Also I saw someone mentioning adding a resistor and cap to the leg of the chip, with a pot, or switch, to add a chorusing, or "modulation" to the repeat.
Thankyou for sharing!

[davecrooks]

Pity about the mindless background music. Good video on a great board. I built an FX box based on this board. Echo/reverb, tremolo and vibrato. Modulating the speed with a Digispark LFO sine wave gives true vibrato.
Similar with square wave for tremolo.

[patrickmcmanus]

I have made guitar pedals but after discovering Ali Express I find it cheaper to just buy the pedals. Often they are modified clones of famous circuits and are better than the original. I am building a Boost distortion fuzz at the moment from Ali Express parts. Lm386 chip for 50c is impressive. Thank for the video I may build your pedal ❤

[msnepaliman]

What you used as power supply for the kit? A battery or Linear Transformer based power supply. SMPS is maybe noisy.

[fransvanhelvoort]

I have the same AE reverb and I must say I can not hear any fuzz in my signal. Why? Because I connected my guitar strait in the delay unit and after that to my amp. What you do is from your guitar into de American sound amp modeler, with the level almost on max, and after that into the delay unit. No wonder you get fuzz because the signal strength is much to high, so the delay unit clips. Just try it the other way.

[needlethread]

this is what i ordered to try to use on an electric guitar,

wasn't so sure if it's gonna work fine. i will be adding this to my diy amp speakers so i can use a mic and electric guitar.
