Overview:
Congratulations on your choice of the LONE STAR as your amplifier and Welcome to the MESA/Boogie Family!
This hand-built instrument was crafted with the finest quality components and designed to provide you with years of musical inspira-
tion and toneful satisfaction.
From a glance you can see the LONE STAR is laid out simply and logically. Its clean, two channel layout provides a platform for ultimate
expression with a minimal learning curve. Though you have probably experienced the magic of its character already, this guide will
help you to understand the interaction of the controls and features…allowing you to find your sound more quickly and deviate from
there easily in new musical environments.
The two channels provide the entire range of gain, from sparkling clean to totally saturated, and anywhere in between. Channel 1(top)
is based on a traditional gain structure to produce angelic and warm clean sounds in its low to medium gain ranges. Like most great
amps, this channel can be driven to clip and produces incredible solo possibilities for blues or roots chording styles.
Channel 2 has a split personality and can either be set to achieve a slightly gainier clone of Channel 1 or, with the flick of a switch
become a high gain preamp. Switching in the DRIVE control adds 2 more triode stages and an additional gain control to meter in the
exact blend of smooth singing saturation. The bipolar nature of Channel 2 allows the LONE STAR to roam effortlessly through both
vintage and modern territory with full channel switching accuracy and an emphasis on soul and simplicity. You can set up the amp for
two low gain channels, one for sparkling clean and the other driven into an old school clip or, one for low gain clean and the other for
high gain singing sustain.
The Lone Star takes channel switching to a new frontier with Multi-Watt™ Channel Assignable Power featuring patented Duo-Class™.
This amazing feature allows you to craft iconic tone as you choose between three different wattage ratings across two different Classes
Of Operation and Wiring Configurations! Select 50 or 100 watts of Class AB wired in Push-Pull for classic bold authority or, switch
down to 10 watts of pure Class A magic wired in a Single-Ended configuration for the ultimate sweet harmonic content.
