BLUE DEVIL GX112

FOREWORD

Dear Customer,
Welcome to the team of BLUE DEVIL users and thank you very much for expressing your confidence in

BEHRINGER products by purchasing the GX112.
It is one of my most pleasant tasks to write this letter to you, because it is the culmination of many months of

hard work delivered by our engineering team to reach a very ambitious goal: To produce the BLUE DEVIL,

which fully satisfies your and our expectations and delivers a superior sound quality, easy operation and

technical specifications. In addition to that the Guitar Workstation is affordable for almost every musician.

The task to design the BLUE DEVIL certainly meant a great deal of responsibility, which we assumed by

focusing on you, the discerning user and musician. It also meant a lot of work and night shifts to accomplish

this goal. But it was fun, too. Developing a product usually brings a lot of people together, and what a great

feeling it is when everybody who participated in such a project can be proud of what we’ve achieved.
It is our philosophy to share our joy with you, because you are the most important member of the BEHRINGER

family. With your highly competent suggestions for new products you’ve greatly contributed to shaping our

company and making it successful. In return, we guarantee you uncompromising quality as well as excellent

technical and audio properties at an extremely favorable price. All of this will enable you to fully unfold your

creativity without being hampered by budget constraints.
We are often asked how we can make it possible to produce such high-grade devices at such unbelievably low

prices. The answer is quite simple: it’s you, our customers! Many satisfied customers, mean large sales

volumes enabling us to get better conditions of purchase for components, etc. Isn’t it only fair to pass this

benefit back to you? Because we know that your success is our success too!
I would like to thank the following people, whose help on “Project BLUE DEVIL” has made it all possible:

s

The existing users of BEHRINGER equipment,whose comments and suggestions have made them the

most important members of the BEHRINGER design team,

s

Thorsten Derks for this marvellous manual,

s

Jan Duwe, whose passionate work has made the BLUE DEVIL as mean as it is,

s

Volker Wagner for the fine mechanics,

s

and all the others, who have made very personal contributions.

My friends, it’s been worth the trouble!

Thank you very much,

Uli Behringer
