PE guitar effects pedal

Other names for this product: Gristlizer,
Courtesy/Thanks to: Practical Electronics (R.Gwinn)

Description: There are numerous guitar effects pedals available today, but there are still many areas of sound treatment in which it is possible for the amateur to produce something which is not just a copy of a commercial effect.


 The Guitar Effects Pedal to be described maked use of voltage control techniques. there are two treatments, a voltage conotrlled ampligier and a voltage controlled filter; either of which can be selected by a switch. These are controlled by an oscillator which produces triangle, square and rising and falling ramps at controllable frequency and amplitude. The combination of four waveforms and two treatments fives eight basic effects, all of which can be considerably modified by adjustment of the controls.
