This is The One; the comprehensive guide to circuit bending I have been searching for since I was introduced to the art in 2003, (by a friend named Reid, oddly enough.) At the time there was nothing but a few scattered resources online. We bought an eighty dollar electrical engineering book because we were anxious to learn and advance what we were doing. If Circuit Bending: Build Your Own Alien Instruments were available then, we could have saved ourselves a lot of confusion, a lot of fried circuits (R.I.P. Lovechild 1,) and Eighty Dollars!
Whether you are just starting out, or have been bending for years, there are countless tips, techniques, and in depth explanations that make Reed Ghazala's book a priceless addition to your workshop (or bedroom.) Even with processes I have known for years, Ghazala boils them down, simplifies and perfects them. And the text never gets boring; there is a perfect combo of technical-layman-mumbo-jumbo-anecdotes-and-asides that keep you turning pages and wanting to know more about the instruments, the art, and the author. You can also see, hear, and read more at Ghazala's website or the book's companion website, (even if you don't have the book yet.)
There is no be all and end all in Circuit Bending (one of the beautiful things about it) but Ghazala's book is the way to begin one's mastery of the art, all coming from the master himself.
