So far, every time I test an audio circuit I have been running it through my guitar amp and pedal board. I have some effects pedals that make everything sound AMAZING. It doesn’t matter if it’s just obnoxious noise or beeps, bops, bleeps and boops or what. It all sounds great.
I have a Boss delay pedal and an Ibanez chorus pedal, wah pedal, distortion… amongst others.
The key is the delay pedal. No matter the input is, the delay pedal creates a rhythmic pulsing that is just heavenly.
So, I wanted to add an echo/delay effect to all the stuff I do from now on. It just seems like the right thing to do. I won’t always have a delay pedal and amp to process the sounds so, naturally, integrating one into the circuit is a must.
PT2399 Echo/Delay Audio Processor IC
Enter the PT2399. I found a delay IC that you can get for relativly cheap on Ebay (10 chips for $11 and free shipping from the seller “connectors_usa” http://myworld.ebay.com/connectors_usa/).
Below is the datasheet and pinout info. The PDF lists the application of the delay circuit which I have included a pic of.

I’m gonna order a batch and try and rig up a delay circuit. I will of course write about the process and let everyone know how it went.
