Some of you may know that with the help of this forum, I have finally succeeded in building a guitar overdrive stompbox circuit that was beyond me. That thread is here:https://www.electronicspoint.com/forums/threads/a-stretch.293212/
Here's some of the things that I think I learned, and also a question about IC Chips:
I thought it would be important to circle back and try to understand how the circuit worked, rather than just build it like a paint by numbers set. I think I learned the following:
The circuit has three major components. The power supply part (which involves constructing a voltage divider), an IC Chip portion that produces the first stage of distortion by cycling the output into the input, and a third component, which involves sending the distorted signal through a second stage, which involves passing it through at least two diodes and a capacitor. This second stage, adds another layer of distortion, giving the final outputted sound, a more distorted quality.
I also assume that the role of the capaciors and resistors, are to regulate and filter the signal- sometimes to make it cleaner, sometimes to slow down current etc., I am not clear however as to how people decide on the values or what is needed to build this type of circuit.
I also learned that there are single op amps and dual op amps, and when using. dual, it is important to short the additional side of the op amp.
I have three questions:
1. Is my understanding correct?
2. A more general question: I often see capacitors shorted to ground in circuits, including the one I am discussing. My understanding is that a capaciot store power temporarily and then releases it to the circuit. Are capacitors shown as shorting to ground, because electricity really travels from negative to positive?
3. Now that i have learned how to build this circuit, i would liek to experiement with different op amps. I have a socket installed and I undersdtan that i may have to chaneg the wiring to match the pin mapping, depending on the IC's specs. Havings said that, what are your top recommendations for a IC Chip for an overdrive stompbox circuit such as this one. Everyone is welcome to male suggestions. AudioGuru, I assume you'll have some recommendations, although i know you've shared some in the past. There are so many posts, that i foudn it hard to find then, so i thought I'd ask here.
Thanks to all! Your advice and expertise is greatly appreciated!!!!!!
