Errata (concerning only the German version of the book)

At GITEC, we have translated the book “Physik der Elektrogitarre” (Physics of the Electric Guitar) into English language. The individual chapters are made available free of charge. The CONTENT LISTING BELOW indicates the chapters as a double entry with a direct link to the respective translation as the respective second entry.

Please note: in the online-version a (small) number of figures and passages is excluded. The complete text including all figures is available only in the printed hard-copy edition (German language).

The (German language) hardcopy edition of the book is now out of print; an electronic PDF-version may be obtained directly from the author (e-mail: manfred.zollner at for a donation.

Well then – here is the complete translation:

Some aspects of

  • string vibrations,
  • interactions of strings vibrations and frets,
  • magnetic inner workings of the pickup,
  • movements of the loudspeaker membrane,
  • sound propagation,
  • the wave traveling in our hearing system, and the
  • movements of electrons in a tube

can be more readily understood by considering the collection of corresponding
