Introduction: Guitar Pedal Phaser

We are still Sean Lowen and Greg Edelston, two students at Olin College in Needham, MA. For our EE Prototyping class, we were assigned to take a piece of commercial eletronics, and reverse engineer it; that is to say, we were to deconstruct it, figure out how it works, and create a detailed schematic and block diagram of the system.
We opted to take apart a guitar pedal; specifically, an Ibanez Phaser PH5 Soundtank. You can find this pedal all over the internet; it's a pretty standard phaser pedal, which modulates the amplitude of the audio signal, similar to a wah-wah. If you don't want to spend $20 on a pedal (and have a lot of electrical parts sitting around), hopefully you can get something out of our reverse engineering!
