Instruction Manual

Overview: Congratulations on your choice of the LONE STAR as your amplifi er and Welcome to the MESA/Boogie Family! This hand-built instrument was crafted with the fi nest 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 fi nd 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 fl ick 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 further and allows you to choose the amount of power and type of rectifi cation you want to combine with each preamp channel. The choices are 50 or 100 watt power ratings and Tube or Silicon Diode rectifi cation. For

ultimate clip-ability and a vintage-squish feel, choose 50 watts and Tube rectifi cation. For clean headroom and tight tracking accuracy, select 100 watts and the Diodes are automatically brought on line to keep things bold and authoritative. These power- se- lectable-per- preamp channels are incredibly intuitive and allow for extreme stylistic accuracy when dedicating the two channels to your footswitching needs.
