4-ch, 100W Tube Amp Head

The Mesa/Boogie Dual Rectifier Roadster Head amplifier puts four independent channels of stunning tube tone at your command! If you love the flexibility of a multi-channel amp but prefer to dial in your tones quickly and intuitively, this amp's for you. The Dual Rectifier Roadster Head gives you crystalline clean tones, authentic grit, authoritative crunch, and even liquid-sustain-type lead tones — and you can use its four channels (plus multiple Modes for each channel) to obtain your favorite sounds and switch among them with ease. A great-sounding long-spring reverb, a switchable Dual Rectifier function on each channel, variable voltage, and 50- or 100-watt operation are also featured on the Dual Rectifier Roadster Head.

Plenty of tonal options from an easy-to-use format
Mesa amps are renowned by touring pros and enthusiasts alike for their range of features, and the Dual Rectifier Roadster is no exception. This all-tube thoroughbred shares a class with only one other amplifier — its brother, the mighty Road King. In fact, the Roadster is a Road King without Progressive Linkage selectable power-tube section and other rear panel features. While those features are outstanding and useful, some players prefer a more streamlined approach. The Roadster now offers the plug-and-play-minded guitarist a way to enjoy a myriad of footswitchable preamp choices without having to deal with a complex power section.


Dial in your favorite clean tones, or choose big, bombastic Boogie sounds
While navigating the lower-gain territory of channels 1 and 2, you'll enjoy an array of classic and contemporary clean tones. Clean and Fat modes add even more options. Once you've dialed in your ultimate clean sound, you can duplicate it in the other channel and modify it for single note applications, a more pushed version or decide to switch to another mode for a radically different sound. Meanwhile, dedicated American blues and English rock sounds reside in the easily clippable mid-gain realms of Tweed and Brit. These dynamic and incredibly expressive modes would make an amazing amplifier all by themselves, giving you a palette of tones that run from clean to crunchy.
Channels 3 and 4 contain all the mind-altering iconic sounds of the legendary Dual Rectifier Solo Head and hand you the keys to the world of high gain — both retro and future. The Raw, Vintage, and Modern modes cover the entire range of gain from a sweet clip to a liquid voice up to a crushing wall of tight grind and are duplicated in both channels. This functionality allows you to either find a favorite sound and dedicate the channels to slight differences, or configure them for wildly different styles. The channels' duplicated modes are a powerful feature, making the Roadster not just an amp for your current style or band but a true lifelong companion to your music. This amp offers limitless configurations, keeping pace with your growth as your playing evolves. 

Choose between 50-watt or 100-watt power 

The Roadster also features Mesa's Multi-Watt channel-assignable power feature, allowing you to choose either 50- or 100-watt power for each channel. This simple-to-use feature expands the potential of each channel mode exponentially by enabling you to lower the power-clip threshold or tighten things up as needed. The two power choices also offer different personalities: 50 watts gives you brighter, elastic bounce; 100 watts means tight-tracking low-end girth and mid punch authority.


Dial in the amp response that suits you
This amp doesn't just stop with a huge array of tweakable tones, however. Mesa applied the same attention to detail to the Roadster's response and dynamics. A switchable Rectifier feature allows you to tune the power supply for the feeling that best suits your style — tube for a vintage-inspired sag, or silicon diodes for tight tracking punch and authority.
Bold/Spongy Power located on the main AC power switch provides a reduced line voltage setting for additional power sag and enhanced top end harmonic content. Its front panel location allows for on-the-fly selection of incoming line voltage with the full 117 volts for headroom and authority, or a reduced voltage setting (like a built-in Variac) for a vintage-inspired "brown" vibe.

Add some "air" to any or all of these great tones
Reverb is paramount in an amplifier this versatile — and the Roadster gets the best! Mesa used the all-tube circuit from their acclaimed Lone Star amp, giving the Roadster a lush, ambient reverb that blooms with added dimension. And because the Roadster's modes offer such a wide range of gain levels and sound styles, each channel is fitted with a dedicated reverb mix control located on the rear panel so reverb can be optimized for each sound.
