Mesa Boogie Dual Rectifier Roadster Head

All-tube 100W four-channel amplifier head from Rectifier series that offers plenty of tonal options from an easy-to-use format. It shares a class with only one other amplifier – its brother, the mighty Mesa Boogie Road King. In fact, this model 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. This model now offers the plug-and-play-minded guitarist a way to enjoy a myriad of foot-switchable preamp choices without having to deal with a complex power section. While navigating the lower-gain territory of channels one and two, user will enjoy an array of classic and contemporary clean tones. Clean and fat modes add even more options. Once he has dialled in the ultimate clean sound, he 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, providing a palette of tones that run from clean to crunchy. Channels three and four contain all the mind-altering iconic sounds of the legendary Dual Rectifier Solo Head and offer 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 user to either find a favourite 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 amplifier not just an amp for the current style or band, but a true lifelong companion to the music. This amp offers limitless configurations, keeping pace with player’s growth as his playing evolves. The amplifier further features Mesa's Multi-Watt channel-assignable power feature, allowing user to choose either 50W or 100W power for each channel. This simple-to-use feature expands the potential of each channel mode exponentially by enabling user to lower the power-clip threshold or tighten things up as needed. The two power choices also offer different personalities: 50W provides brighter, elastic bounce; 100W means tight-tracking low-end girth and mid punch authority. A switchable rectifier feature allows user to further tune the power supply for the feeling that best suits his style – tube for a vintage-inspired sag, or silicone 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 V for headroom and authority, or a reduced voltage setting (like a built-in Variac) for a vintage-inspired brown vibe. Mesa also used the all-tube circuit from their acclaimed Lone Star amp, providing the amplifier a lush, ambient reverb that blooms with added dimension. And because the amplifier’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. The amplifier is in total equipped with four 6L6, six 12AX7 and two 5U4 tube complements. Each channel features independent Gain, Treble, Mid, Bass, Presence, all-tube long-spring Reverb, channel-assignable Dual Rectification with Recto Tracking (diode or tube tracking) and all-tube Effects Loop with send level control (over all channels when activated). A true hard-bypass switch removes Effects Loops, Output Level, and Solo Level controls from signal path. A fitting slip cover is included. Dimensions: 250 x 650 x 298 mm. Weight: 21.77 kg.
