Volume 2: Tracking Down Your Dream Tone - Build Your Own Guitar Effects Pedals: The Operational Amplifier

Build Your Own Guitar Effects Pedals - Volume 2: The Operational Amplifier(With a foreword by Brian Wampler, president and founder of Wampler Pedals, Inc.)Ready to dive deeper into the DIY world of guitar pedals? Like the first volume, "A Beginner's Guide", this book aims to provide the knowledge necessary to understand the inner workings, or electronic circuitry, of effects pedals. By studying this book, you will lay the foundations for developing your own ideas for effects circuits or making a wide variety of modifications to existing circuits.Volume 2 deals specifically with the so-called operational amplifier - in particular with the classic among them, the TL072. Such operational amplifiers are the electronic core components of numerous effects pedals on the market. Regardless of whether it's pedal types such as overdrive, tremolo, reverb, phaser, fuzz, delay or others - they can be found almost everywhere: the small, inconspicuous chip components in which the operational amplifiers are housed.As there are so many ways in which these operational amplifiers can be used to achieve the desired sound effects, the focus of this book is more on theory, looking in depth at the way some of the most important basic circuits work. There is a little more math than in the first volume, but it should not be off-putting. Rather, the formulas and calculations included are intended to make the functions and characteristics of operational amplifiers easier to understand and thus help you design your own pedal circuits. And so that it doesn't become too dry, the theory is accompanied by numerous interesting, exciting tips and hints on practical applications.At the end of the book, the newly acquired knowledge is put into practice and an overdrive, a tremolo and a reverb pedal are built.Contents of this book:Detailed presentation of the most important operational amplifier basic circuits required for pedal construction.Answers to basic questions such as:What is meant by an inverting and non-inverting amplifier and how do they work?What is wet/dry control good for and how exactly is it integrated into effects circuits?How is a buffer or impedance converter constructed and how is it used?What is a low-frequency oscillator circuit (LFO) used for and what does it have to do with a car windshield wiper ;-)?What is phase cancellation, what causes it and how can it be avoided?... and much moreHow to simulate the operational amplifier using LTspice.Instructions for determining the input and output impedances of the effects circuits using simulations.Tips and hints for the practical implementation of the pedals presented in the book (overdrive, tremolo, reverb).A collection of formulas for calculating the most important parameters relating to operational amplifiers as a helpful basis for designing your own circuits.Who is this book for?Perfect for anyone who wants to understand the electronics and functionality of effects pedals and develop their own circuits. Together with the first volume, "A Beginner's Guide", it forms a comprehensive and useful reference guide.Have fun and success immersing yourself in the world of operational amplifier circuits and building your own effects pedals!
