Here is a list of books about DIY musical electronics design. If you have read them or know of any other books that I missed, please comment below.

Handmade Electronic Music
Nicolas Collins
Routledge
ISBN: 978-0-415-99873-4

Handmade Electronic Music covers circuit bending and simple musical electronics, and is the inspiration for many of the projects I feature on NerdSonic (like this one). The author manages to keep his descriptions of technical subjects simple and readable, which makes this a great book for beginning hardware hackers. The example projects are creative and fun – you won’t find any bland voltage divider schematics here! If you want a preview, check out the New Circuits section of Nicolas Collins’ website.

Make Electronics
Charles Platt

Make Electronics is a very readable primer on electronics in general. Highly recommended for delivering more complete discussion of electronics theory than most of the music-focused books.
