Question:
I have seen theese everywhere (duh) but I have no idea how to read them. Anybody want to help me figure these things out?

Answer:
That's an excelent site. There's only few notes I might add.
First, a lot of the time, DC power symbols with two wires are not shown. Instead, the schematic might show you how the battery is connected to ground, but more often than not there will just be an arrow or a circle or even just a wire that is labeled with the supply voltage.
Second, with opamps, there are other pins that aren't shown on the standard symbol. In guitar effects, unless it says otherwise, VCC+ connects to +9V, and VCC- connects to ground. If the wires are drawn in, the will stick out the top and bottom of the triangular symbol. With a single opamp in an 8 pin package, there are two other pins, but I still have no idea what those are actually used for.
And lastly, with JFETs, a lot of the time, the source and drain pins are not labeled. Usually the drain is the one that's connected closest to the power supply, and show towards the top of the schematic. The source is shown at the bottom and connect to ground. The gate is always the one with the arrow. In theory, JFETs work if those pins are reversed, but it's still better to get them right. I don't remember what part of the manufacturing process makes the two pins behave differently.
Answer:
but how do I know what those things mean? I mean, say I take a look at a distortion stomp box schtc. , hwo do I know how the thing gets distortion? or do I just need to figure that stuff out?
Answer:
"how it gets distortion" is based off more than one component, and you'd have to understand how the circuit works. caps, diodes, all sorts of components can alter sound freqs, and in different ways based of how they're connected. for instance, you guitar's tone pot is basically a cap and a variable resistor, change how they're connected and it changes from a high-pass filter to a low-pass. i just got back from electronics class, so i'm not quite up to going into more detail, i've got some homework on signal amps to do.

What's your major, What5647? (electronic engineering?)

Originally Posted by Building429_Boy That's what I'm considering for my major. Choices, choices... yeah, tell me about it. actually, the EE choice was pretty easy for me, seeing as i love electronics, math, science, etc. another huge factor: if i get an intership with the government at the local naval air station they'll pay for a lot, if not all of my schooling, and i can get my degree locally. although i do kinda want to leave for school, but this is were God has me for know.
Answer:
If you are after the details of how a stompbox works, I can't HIGHLY recommend this website enough:
