Electric Guitar Tuner
Approx construction cost US$18

Electric Guitar Tuner project -- EPE Online April 2002

Six fixed frequencies and an l.e.d. help you to stay in tune

Guitar tuner projects range from simple devices having l.e.d. displays to highly complex units using signal processing stages, frequency to voltage converters, and sophisticated displays. This unit is very much in the "cheap and cheerful" category, but it nevertheless works very well.

More details on this construction project can be found in the April 2002 issue of EPE Online, the world's first web-delivered electronics and computing hobbyist magazine.
