Project overview

This JFET preamp overdrive/distortion/fuzz is a Benson Chimera 30 Watt amplifier inside a box that has it all. It delivers a clean boost, soulful-bluesy overdrive, and even fuzz and distortion; all this versatility reached effortlessly.

Introduction

The Svenson Preamp is a circuit that captures the Chimera amplifier soul by substituting vacuum tubes for JFET transistors, like we have seen in many other preamps in a box or in Wampler Plexi.

This circuit is a jack of all trades, so better be ready to have all in one pedal: this circuit adds thickness to your tone and gives a blues drive-like sound without going to metal. Enriches your sound by incorporating harmonics and a very musical EQ into your signal chain. Delivers rusty overdrive/distortion waves while maintaining all your guitar’s original character. All of this, with the ability to dial effortless in the exact feature you want!
