BLUE DEVIL GX112

1. INTRODUCTION

Thank you very much for expressing your confidence in BEHRINGER products by purchasing the BLUE DEVIL

GX112. With the BLUE DEVIL, you have acquired a Guitar Workstation that sets new standards in guitar amp

engineering. When developing the GX112, our top objective was to reproduce the direct sound of analog

guitar amps as perfectly as we could and combine it with latest DSP technology—while focusing on a user

interface that can be operated intuitively.
BEHRINGER is an audio engineering company that has been successfully developing products for studio

and live applications for many years now. Our range of products includes microphones and a variety of

19" devices (compressors, enhancers, gates, tube processors, headphone amps, digital effects devices,

DI boxes, etc.) as well as various monitoring and P.A. speakers plus professional live and recording consoles.

The name of BEHRINGER stands for no-compromise quality, fully-featured products and exemplary service—

even years after purchase—as well as sensationally low prices, which allow any ambitious music lover to

make their musical dreams come true.
We also set great store by flexibility, which has become a particularly important factor in the music business

over the past few years. Modern guitarists need to offer a broad range of sounds, but should still be able to

play in different kinds of applications at short notice: home recording, studio, live concerts. For this reason, it

has always been our prime concern to give you a Guitar Workstation that offers you a complete set of

functions, but can still be operated intuitively and quickly—no matter what kind of style you play.
Unfortunately, conventional guitar amps are often not fully designed and developed. Moreover, many manufacturers

of traditional-style guitar amps are somehow afraid of using state-of-the-art technology. The BLUE DEVIL, on

the other hand, is a pioneering guitar amp that has considerably more functions than any conventional 2-channel

amp with a built-in spring reverb. Still, you can use the GX112 so that it mimics an excellently sounding

2-channel combo amp with an—admittedly—good spring reverb. However, we recommend that you make

yourself familiar with the BLUE DEVIL in full detail, so that you know what each of the many functions does and

be able to fully exploit the numerous effects and control options provided.
As technology advances, you’ve got to keep track of latest technological breakthroughs to avoid falling by the

wayside. Since the first presentation of the BLUE DEVIL at Frankfurt Pro Light & Sound in 1998, we have

continuously improved this amp and included many of your valuable suggestions. We have spared neither

expense nor effort, to test different types of circuitry and speakers until the results gave us complete satisfaction.

After all, we really want to give you fully designed and developed products that meet your expectations in

every respect. The BLUE DEVIL shall be a useful tool for years to come, which is why we’ve equipped the

effects modules of our Guitar Workstation with EPROMS that can be updated. In this way, we can keep on

working on new algorithms and considering your ideas and suggestions. The resulting software updates will

be made available for free on the Internet, so as to ensure that your amp will never be outdated.
We’ve packed our entire experience in this latest generation of guitar amps. Many people contributed to this

project of intense development: studio musicians, collectors of vintage guitar amps, music and guitar lovers

alike. We even invited guitar amp tuning experts to help us develop an amplifier that gives you the best of all

worlds:

s

Sophisticated analog technology with a “feel factor” only analog technology can provide.

s

Perfect simulation of tube-specific nuances to make up for the drawbacks encountered in tube designs

(short service life, heat dissipation, poor mechanical stability).

s

Latest DSP technology to give you a broad range of modern high-gain and vintage-type effect sounds.

s

Rugged and solid construction which even withstands roughest handling.

s

Intuitive operation, so that you can focus your mind on what is most important to you: your music!

+

This  manual  first  describes  the  terminology  used,  so  that  you  can  fully  understand  the

BLUE DEVIL and its functions. Please read the manual carefully and keep it for future reference.
