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, then 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.

Mesa/Boogie Dual Rectifier Roadster Head 100-watt Tube Amplifier Head at a Glance:
  • Plenty of tonal options from an easy-to-use format

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 one and two, 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 three and four 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 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 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.

Incredible Amplifier

Forget about all the other amps. When you make up your mind, and you're really ready to get serious about your guitar tone, beg, borrow, finance, whatever it takes, and buy this amp. Sparkling clean tones from channel one, classic Marshall tone from Channel two, Screaming tube distortion from channels three and four, and three modes per channel. The distortion from this amp is the best sounding crunch I've ever heard. Wanna get that HUGE guitar tone sound like John Sykes on Whitesnake's "In The Still Of The Night", or Brad Gillis on Ozzy's "Speak Of The Devil"? Maybe you want a Buddy Guy dirty strat tone, or an AC/DC Back in Black sound- This amp is what you need. Throw your distortion pedal away... This is the best amp I've ever heard. If you buy it, you'll keep it forever

Best amp I've ever played

I owned a 3 channel dual rec but had to get rid of it over a year ago. Recently I was looking into getting another amp, went down to a local boutique shop, and tried out various amp heads. Orange, Engl, Mesa, Rivera. I again was drawn to the boogies. I was intrigued by the roadster and did quite a bit of research. After playing it in store, I was immediately sold. 4 channels, reverb, it has everything. I was curious if it was as aggressive as the original rectifiers and I can gaurantee it is. Voiced just slightly darker, it gets plenty of chug. I play in various projects, mostly metal and melodic rock, so I utilize a lot of the features. Seriously, don't think twice. Grab this amp head, you won't be disappointed.Current Rig: Mesa Dual Rec Roadster/ straight 4x12 recto cab

Last head you'll ever need... seriously.

This thing is amazing. I had a Triple Rec for 10 years but I disliked the clean channel a lot. I'd actually take a 2nd head to gigs just cover the clean. Lugging extra gear is no fun! I then heard the Rect-o-verb had acceptable clean (plus reverb obviously) so I tried that. It's a Single Rec, and I had to disagree about the clean... not so great. Slight better than the Triple, but nothing to write home about. It broke up way too early.The only two Rectifier heads I hadn't tried yet were the Roadster and Road King. I didn't feel like I needed the extra bells and whistles of the Road King, so I went with the Roadster in the end. I'm so glad I did. It's the perfect head. Recto gain when I want, sparkling clean when I want, plus 2 more channels to set up with different levels of dirty or clean. I mainly use channels 1 and 4, they're my favorite. 2 and 3 are great too, but I haven't paid them enough attention to let them shine... too impressed with 1 and 4 I guess. haha. I'll have to dig a little deeper into 2 and 3 down the road. I've had this head for about 3 weeks I'd say and I still end up randomly telling my other musician friends "Oh my god, I love this head..."

Buy it for the flexibility, Keep it for the AWESOME

I bought this amp for the 4 separate channels. It has amazed me ever since. Right after I got it, our drummer came over to my house and was stunned at how good it sounded.Like most other folks, I use channel 1 for a sparkling clean tone. I up the gain on each channel with 4 just screaming. No matter what you are playing, there is a channel for it. The effects loop is really good. Tuner mute is really handy. Had a friend point out that I could have bought 2 amps of a different brand for what I paid for my Roadster rig. To me, it was more than worth it.

Master of All Trades

I've owned this amp for four years, and it has never ceased to deliver on any occasion. I've used it for pop, country, funk, metal, and indie rock gigs and sessions, all requiring wildly different tones. Even four years later, I still feel like I've barely scratched the surface of what the Roadster can really do, and regularly twiddle knobs and switches just to see what new sounds I might discover. On any given day, I can have Bassman grit, Vox chime, Plexi crunch, and Dual Rec growl just a footswitch tap away. Not to mention separate wattage, reverb, and FX loop controls per channel, a built-in Variac, and the ability to swap 6L6s with EL34s. Quite possibly the last amp you'll ever need.

Sweetwater Advice

Chris McCown

Mesa's are renowned as being tone machines. Roadster is second only to the flagship Road King, and in fact shares many of the same features as Road King. If you like what you've heard from a Dual Rectifier but need more versatility (i.e. spring/tube reverb, one more channel, flexible power options, etc.), then this is going to suit you well. As a gigging musician playing various styles, and a guitarist who has owned a Dual Rectifier and swears by the Mesa tone, this is the amp I chose to fill my needs. It's truly a workhorse amp, and each voice on each channel (TWELVE voices in all) are more than usable. A Hand Built Tone Monster, that's what I would call it.
