Rectifier Box

Project overview

The Rectifier Box is my first attempt to capture the essence of the Mesa Boogie’s Throttle box, one of the best High gain distortions I ever heard, with a really interesting Mid-cut section.

Introduction

Put the Rectifier Box distortion pedal before your amplifier and get ready for pure aggressiveness and power!

This is a difficult to build High gain Drive. With an average availability of components. Just take special notice that this project works with a 220uH inductor.

• Works with two TL074 and one JRC 4558
• 3pdt Switch on board
• 2 DPDT, Input selector, and Mid-cut EQ.
• A very useful mid-control pot and switch based on an inductor.

Controls

• Gain
• Volume
• Tone
• Mid-cut
• Toggle to choose the input mode
• Toggle to enable the Mids mode

On this drilling template, I made some changes to make it fit properly in a 1590BB enclosure. It fits super tight, and I replaced the onboard pots for regular ones. For the DC jack, I recommend using the smaller ones.
