INTRODUCTION

The Dark Art: 

In an age where guitar players have developed an unhealthy fascination with pre-amp distortion, the fabled sound of a tube 

power amp being pushed hard has almost passed into history.  Until now that is!

The GH100TI is a single channel master volume style head, designed specifically to meet the tonal demands of Tony Iommi.  The GH100TI is 
equipped for out and out metal with 5 stages of gain permanently engaged and several cunning high gain modifications, this amplifier is the 
ultimate partner to one of the most influential players of all time.   The hand wired 100W output stage is built to deliver:  The harder you 
drive it, the better it sounds.   The GH100TI is designed to be used with the GS412LA and GS412LS cabinets - to enhance the amplifiers 
huge tonal range and produce stunning tone at any volume.

Your GH100TI should give you years of trouble-free amplification, however please take time to read this manual and familiarise yourself 
with the controls as it will allow you to get the best from your amplifier.   We hope you enjoy using your GH100TI as much as we enjoyed 
designing and making it.  Best wishes from all at Laney

Dear Player,

Thank you very much for purchasing your new Laney product and becoming part 
of the worldwide Laney family. Each and every Laney unit is designed and built 
with the utmost attention to care and detail, so I trust yours will give you many 
years of enjoyment.

Laney products have a heritage which stretches back to 1967 when I first began 
building valve amplifiers in my parent’s garage. Since then we have moved on from 
strength to strength developing an extensive range of guitar, bass, public address 
and keyboard amplification products along with a list of Laney endorsees that 
includes some of the world’s most famous and respected musicians.  At the same 
time we believe we have not lost sight of the reason Laney was founded in the 
first place - a dedication to building great sounding amplification for working 
musicians. 

Warm Regards, 

Lyndon Laney   CEO
