Mesa Boogie Lonestar - Clean preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Lone Star represents Mesa Boogie's return to elegant simplicity after decades of high-gain complexity, offering selectable 30- or 100-watt operation and two channels optimized for pristine clean and expressive lead tones rather than extreme saturation. Its clean channel is widely regarded as one of the finest American clean tones available from a production amplifier. The Lone Star became a favorite among country, blues, and roots players who prize touch sensitivity and dynamic range.
