Freeman Boost

Project overview

The Freeman Boost is one of the most interesting and versatile pedals out there. The first part of the circuit is a crystal clear boost that pushes the front of your amp for thick harmonic overdrive.

The second section is a three-band active EQ to tailor your tone to taste.

With a simple toggle, you can select to bypass the EQ section or not.

Introduction

The Freeman boost is one of the most useful tools you can get on your pedal board. This circuit pushes a pure, clean signal to conjure the absolute most from your tone.

Turning the boost control is your ticket to volume increase, pushing the front of your amp for thick harmonic overdrive, or balancing between two guitars with varying output.

Whether you’re after a tone tailored by its active mid, treble, and bass controls or the pedal’s ability to achieve total transparency – thanks to its onboard EQ Bypass switch – it’s all in there.

We’ve even added a useful tight control for reigning in your tube amp’s bottom end when boosted.

With an internal voltage inverter, the OpAmps works at double the double input voltage guaranteeing plenty of transparent headroom on your tone.
