OUTPUT & SOLO CONTROLS: (Continued) SOLO: This control can only be activated if the correct Footswitch is connected SOLO is an additional fi nal output level control wired in parallel with the OUTPUT control. It is capable

 

of a setting above that of the OUTPUT control and can not be set below. The amount

If the power section is either not a part of the sound (super quiet), or producing all its

rated wattage (super loud), there is very little signal for the SOLO control to work with. By

using the Footswitch and selecting SOLO , a pre-settable boost in overall levels is possible

 

 

on the fl y...giving you some control over your levels when it’s time to step out. Engineers

may give you a bit of a frown the fi rst time you use it...but isn’t it time you heard yourself. It might even prevent them from punishing you with the dreaded monitor or sidefi ll version of your tone.

POWER: TWEED / OFF / ON This sideways 3 position toggle switch determines the status of the incoming AC power. Your LONE STAR incorporates a built-in VARIAC feature that enables you to reduce the line voltage to approximately 93 volts (with a steady 117 at the wall).This TWEED power setting produces a spongier, scoopier response and allows you to power clip the amplifi er at lower overall volumes. It is especially useful in achieving old school clip sounds in Channel 1 and Channel

power setting often, tube life would increase substantially.

 

ON

For maximum power, normal response and the greatest headroom use the ON setting of the AC power switch.

STANDBY: Perfect for set breaks... this toggle switch also serves an even more important purpose. In the Standby position the tubes are at idle so that during power up they may warm up before being put to use. Before Power is switched on make sure the STANDBY switch is in the Standby position.

ON

Wait at least 30 seconds and then fl ip the STANDBY switch to the ON position. This prevents tube problems and increases their toneful life substantially.

Now that we have reviewed the features and controls of the Front Panel and you have a handle on how they interact to achieve the sound you want, let’s move to the Rear Panel and cover the features found there.

LoneStar Amplifier specifications

The Mesa/Boogie LoneStar Amplifier is a standout choice for guitarists seeking a high-quality, versatile tube amplifier that excels in both clean and overdriven tones. Designed for performers who require reliability and tonal variety, the LoneStar is a blend of vintage warmth and modern performance, making it ideal for various musical genres, from blues to rock to country.

One of the main features of the LoneStar is its dual-channel configuration, allowing players to toggle between pristine clean tones and rich, dynamic overdrives. Each channel offers independent tone controls, including bass, mid, treble, and presence, enabling precise sound shaping. The amplifier also includes a unique "Boost" feature on the overdrive channel, which provides an additional gain stage for solos or dynamic passages.

The LoneStar is powered by a quartet of EL84 power tubes, which deliver a sweet, harmonically rich output. This choice of tubes contributes to the amp's tonal character; the EL84s are known for their smooth breakup and dynamic response. Additionally, the amplifier can operate in either 30-watt or 15-watt modes, offering flexibility for both stage and studio environments.

A hallmark characteristic of the LoneStar is its use of the "CabClone" technology, which gives players the ability to silently record or practice by sending a speaker-emulated signal directly to a mixing console or recording interface. This innovation means you can achieve high-quality recordings without the need for a mic'd cabinet.

The amplifier also features a rugged design, with a sturdy chassis and durable tolex covering, ensuring it withstands the rigors of touring. Its aesthetic appeal, paired with its functional controls and footswitch capabilities, makes it a favorite among professional musicians.

With its distinctive tone, versatility, and advanced features, the Mesa/Boogie LoneStar Amplifier has established itself as a modern classic in the amplification world. Whether you are seeking lush clean sounds, soaring leads, or earthy mid-range overdrive, the LoneStar provides all the tools you need to shape your signature sound effectively. For players who appreciate quality craftsmanship and performance, this amplifier is an investment that pays dividends in tonal richness and reliability.
