Guitar Pre-Amp with JFET 2N5457

Schematic Diagrams      Comments Off on Guitar Pre-Amp with JFET 2N5457

Designed by Don Tillman, this guitar pre-amp circuit design is dedicated for people who don’t like op-amps. This circuit is a discrete JFET pre-amp design, use 2N5457 as the main component. It has low noise, low distortion, low feedback, overloads gracefully, is small, etc. Overall gain is 3db (2X) or… Read more »

Guitar pre amplifier based TL071

The Guitar preamp circuit is very simple, using only a single integrated circuit, a type TL071 OP AMP. The title is an exaggeration, given that the gain of the circuit is intentionally low. When we talk about pre-amp, you can expect amplification often great … that is not the case… Read more »
