Of the three musical electronics project books, this one was the most difficult to understand, since the author uses British (or European? Metric?) notation on some components. Once I got used to that, though, everything fell into place.
Not that I ever built any of the projects. I got some ideas from Penfold's book, all of them added to a big folder with all my other electronics/music stuff, but nothing ever seemed to get built. I was always working on something else--fixing a car, learning a song, playing along with Rush tapes (NEVER the LP's!), stripping electronic components from broken TV's, radios, or whatever. I've got a sizable collection of resistors, capacitors, and all that...in storage.
Penfold gives us 16 projects after a cursory course in soldering, assembly, and testing:
Auto-Wah (he spells it "Waa")
Dual Tracking effects unit
Dynamic treble booster
Improved distortion box
Thin distortion unit
The schematics, assembly drawings, and parts lists are well-done; the projects are built up on simple breadboard with point-to-point wiring, but since there doesn't seem to be anything critical you could probably get away with the "dead bug" assembly method to make things take up even less space.
Some of the schematic symbols and part numbers didn't match anything I'd seen before, but that was before the Internet and Google, so sourcing most of the active components (transistors, integrated circuits) or equivalents shouldn't be too hard.
