1 Project Overview

2 Introduction & Usage

INTRODUCTION

The Vortex Amp Distortion is a recreation of the Bouteek Distorter Preamp, a limited-release pedal

from 2009 that flew largely under the radar. It was rumored to have the involvement of someone from

Peavey, but otherwise very little is known about the company.

Bouteek released three other pedals. The Overdriver Preamp and the Twin Drive & Boost (Ultimate

Drive) were both released in 2009. The Oil Cap Preamp followed in 2011. Each was only available for

about a year or two. By mid-2015, Bouteek was fully extinct in the wild.

Circuit-wise, the Preamp Distorter is an interesting combination of familiar building blocks. It starts

with two Tube Screamer drive stages with variable clipping options. From there, it goes into a Big Muff

tone control stage. Using two CD4066 switches, it selects between two different sets of low-pass and

high-pass filters used on both ends of the tone control. At the end, there is a gain recovery stage.

This project would not have been possible without the help of Paul Marossy. He did most of the work

tracing the pedal several years ago, but ran into a couple of issues that caused it to be shelved before it

was fully verified. Aion FX did a second pass to work out the problem areas and verify the tracing work

independently, and then designed the PCB.

USAGE

The Vortex has the following controls:

• Pregain and Drive are the first two gain stages, simulating the setup of a high-gain amplifier.

• Tone pans between a high-pass and low-pass filter. The two filters themselves are impacted by the

Tone toggle switch.

• Volume controls the overall output of the effect.

• Clipping (toggle switch) selects the clipping diodes which changes the character of the drive tone. In

Vintage mode, both stages are clipped with silicon diodes. In Rectifier mode, the Pregain stage has

no diodes while the Drive stage uses LEDs for clipping.

• Tone (toggle switch) selects between two different sets of high-pass and low-pass filters for the

tone control, altering the frequency ranges that are panned by the Tone knob.
