Guitar Pre Amp Circuit

This is a circuit for guitar pre amp that has a few interesting characteristics that separate it from the “normal” – assuming that there is such a thing. This is simple but elegant design, that provides excellent tonal range. The gain structure is designed to provide a huge amount of gain, which is ideal for those guitarists who like to get that fully distorted “fat” sound. This is the figure of the circuit;

However, with a couple of simple changes, the preamp can be tamed to suit just about any style of playing. Likewise, the tone controls as shown have sufficient range to cover almost anything from an electrified violin to a bass guitar – The response can be limited if you wish (by experimenting with the tone control capacitor values), but I suggest that you try it “as is” before making any changes.
