Guitar Input for Multi-Effects Unit

In this issue we also published a digital multi-effects unit. This circuit can only be used with line level signals, such as those used by keyboards and the effects loops of mixing panels. To make that circuit suitable for use with electric guitar signal levels we now present a simple but effective amplifier circuit.

 

The Elektor Digital Multi-Effects Unit published in this same edition contains a number of nice effects that would not be out of place in conjunction with an electric guitar. Here we publish a preamplifier, which makes the input of that circuit suitable for connecting to an electric guitar. This preamplifier, which in addition to a high-impedance input, also has the option of adding an effect commonly used with electric guitars, namely distortion.
