How to Make 9 Volt Portable Guitar Amplifiers

Good book for the absolute beginner. It describes one way to make a small guitar amp, it's very specific. If you want to make a more powerful amplifier or make modifications, you will have to consult other material. In other words, the author made one or two of these, with minimum electronics knowledge, and published a book on what he did. Welcome the world of Amazon: do a thing once, and write a book, self publish on amazon. You don't have to know sheet from shinolla.I bought this, and several other more comprehensive books on electronics, in order to get an overview of small battery operated guitar amps, there are many excellent how to books on electronic circuits written by professionals, not amateurs. If you want to to understand capacitors, amplifier circuits, diodes, resistors ect, there is some good general info in this book as well; Its a good start. I recommend the book.

Here's the problem with a book like this. You can go online and get all the information you need to build one of these amplifiers and not spend any money on a book. Cigar box guitars are a great hobby. Once you start thinking outside the "box", you would be surprised what you can come up with. Same goes for these amplifiers, you could buy a kit, they're cheap. and get started. Have some fun. Get away from the TV. Do something and do it now.

Awesome, easy to understand book for a beginner (like me). Have had fun reading this and am gathering parts to build my first 9-volt portable guitar amplifier. Very cool book, and the updates on the web page are nice, too.

I was a little bit disapointed when the book arrived today. I thought, I'd learn a little bit more about 9V amps, building my own amp, tweaking it, aso. Everything I got was a big book with countless b/w pics which are difficult to use. You'll see inches of white wiring stuff and start puzzling around, where they were fixed. Buy a breadboard (the book is built upon this thingy)! I thought, I would get a pcb image, a schematic, instruction how to built a tone control for my "boutique 9V amp", which parts are used, and other useful stuff. It's missing (not even a drawn schematic is present). If you'd put all unnecessary pics in the wastepaper basket, you'd get a book which will be a third of the printed one. I think you understand: every www-diy-board gives you more information, for less money.2 stars only for the fact, that you'll get a link to dld a full colour version of the book.

Get's the job done real simple. Doesn't go beyond one model and doesn't give options. The title says amplifiers plural.

If you are a complete beginner this is a good book for you! If you are a skilled ampbuilder, not so much.

This book focuses more on tools and soldering than on amplifiers. It keeps referencing website content that isn't really available yet.

Ever had the desire to build your own 9 volt portable amplifier, but you knew that the technical know how always seemed like a foreign language barrier to you....Well this has to be the ultimate " Of course you can build it " book on the market today.Every necessary step is shown in full detail , accompanied by excellent photos that will guide you through this extremely enjoyable and rewarding project.The end result will be a great sounding amp , built to your own design specifications.Every Tool and part is fully explained , using terminology that anyone can understand and follow.All the electrical componentry is fully explained (and with photos) you will no longer be a wiring dummy when you read words like Ohms, resistance,circuits,potentiometers,capacitors, etc etc etc.There are many great teaching points in this book and I know you will enjoy working through it, one of which is the facility to "try before you fly" by using a breadboard to check your chosen components before any soldering is done, how neat is that.The book will also teach you how to set up and test out many guitar modifications before actually doing them on your valuable instrument, that has to be tops for me.The writers have also included links to supply points so you don't even have to leave home to get the parts.Many many thanks Indyebooks, you certainly know your business and I look forward to your next publication.

Not much to say really. apart than don't waist your money on this book, theirs more info online about building amps than here.

Invaluable advice for my hobby of making cigar box guitars and battery driven amps.

I'm finding this helpful is explaining the basics. Looking forward to building my own 9v amp.Would help if he listed the parts needed.

Una guia paso a paso para construir tu propio amplificador portatil a 9v. Biene muy bien detallado y explicado, y no son necesios conocimientos amplios de electronica.El pero está en las fotografías en blanco y negro.
