There are a lot of different blogs and videos about making an echo or reverberation effect circuit or device. Like most of them, I too used a PT2399 chip for this circuit but I'm explaining here the basics of echo effect and how to use this chip to immitate this effect. In this video you will come to know how I failed to make this circuit at first attempt and what changes I made to make it work. This is just a small documentary to portrait this whole project. I've given my best to demonstrate and explain about everything related to echo/reverb. effect and how to implement it artificically in audio and musical circuits. If you have any doubts or still have problem regarding certain topics in the video, please lemme know.
Enjoy :)

You've shown only echo adjustment, where is reverb??

as much as i appreciate the breakdown, throwing in screaming memes 10x the volume of you talking is inexcuasble

Can we use DPDT On On Push Switch to bypass Reverb ? could you share the scheme

Is it possible to build a Guitar Effects pedal with it.

What pin on the pt2399 did you connect the microphone too? Pins 10(op1-in), 11(op2-in), 13(lpf2-in) or 16(lpf1-in)? Also, which is the output pin (to connect the speaker) of this chip? There is pins 15, 14, 12 and 9? This chip, has me very confused. Please clarify some of this for me. Thank you kindly

so the first schematic is wrong, the second works ?

I wonder what the longest delay IS. Only one way to find out. Now where did I put my Stop Watch??? Great video. I’ll be playing around with this IC today. God Bless

I am wondering how I can power this from a 9v battery? Do I need to somehow drop it down to 5v for this circuit?

Helow sir thanks to your video i made the ehco effect processor...
@melinaleonne3841 2 years ago

Hello! Thanks for the video man. It helps us a lot! One question. What can I use so the delay time is determined digitally by arduino? Thank you in advance.

Why don't you make this for me and whatever is the cost I will send on your account. You can ship it to me.
