Mini Rectifier 

Mesa/Boogie Mini Rectifier Twenty-Five Head

MINI RECTIFIER® TWENTY-FIVE: ICONIC RECTO TONE IN AN ULTRA COMPACT 'MINI' AMP— Weighs Only 12 Pounds!

The Mini Rectifier Twenty Five rides atop a 20-year legacy of world-class high gain performance and hit-making sounds that have been at the core of – and even a catalyst for – some of the very best of Modern Rock. You will quickly find that its Mini moniker and physical size bear no resemblance to its stature, power and command over blistering, tight overdrive in the realm of big gain Tone.

Don't think for a moment this is a trendy down-line toy or marketing-derived imitation of our mighty Recto. This is the real deal… in every way a high-end instrument. Lurking within this expensive metal chassis, lies one of our most expressive and nuance-enhancing circuits to date and it creates an exciting, adrenaline-producing Tone machine… one of the most fun to play in the entire MESA collection.

Whether you're rockin' hard or putting the immense versatility of the Mini's four Modes to bear on a variety of styles, you'll get years of inspiration and enjoyment from this little gas-in-glass-powered jewel. We always strive to build classics, icons that you'll treasure amongst your most valuable musical instruments. From the feedback we've received thus far… it seems the Mini Recto is on its way toward achieving that status.

Mark V Head

The MARK V is really a collection of amplifiers.

IT TOOK 40 YEARS of Randall Smith's experience designing high-performance tube amps to get this much TONE under one roof and keep it easy to dial. More than a collection of amplifiers, the MARK FIVE™ is a living history of MESA's® contributions and a tribute to the evolution of electric guitar tone.

THEY'RE ALL HERE: the MARK I®, the MARK IIC+®, the MARK IV®… all these are faithful recreations that benefit from our decades of refinement and leave many saying they're better than the original! More than our Greatest Hits, you'll also find some new Brit-inspired circuits here that rival these classic Boogie sounds and are destined to become iconic on their own merit.

No less than 9 patents stand guard over your Tone… ensuring your investment will be protected and your amp will hold its value. (MARK II C's and MARK IV's still sell for more than their original purchase price). Beware of Imitators!

Overview:
The MARK V is really a collection of amplifiers. There are far too many circuits and sounds to think of it as merely an amp. It is also a living history of our company. From the ground breaking MARK I that introduced the world to high-gain with it’s cascading pre amp, to the Mark II - the world’s first high gain Dual Mode Channel Switching amplifier and it’s later siblings that introduced Simul-ClassTM power. From the MARK III that ushered in the era of 3 Channel footswitching performance, to the MARK IV which gave all this power individual control, the MARK V is the embodiment of the last 40 years of guitar amp history.

PREAMP:
Three distinct Channels present the 3 footswitchable sounds in a simple to dial platform, but don’t let that fool you... beneath each set of controls lies another layer of performance. Each preamp Channel contains 3 distinct Modes that are controlled by a simple mini-toggle MODE switch found in the upper left corner of each Channel. This switch is responsible for the voicing of each Channel. In some cases these voicings are related by style and give you important musical differences within a gain structure and sonic theme. In other cases, both gain and EQ are radically altered to achieve drastically different sounds - yet these sounds appear on the same set of controls. This is a result of needing a certain circuit architecture and Tone control string to achieve a particular sound style. Sometimes these extreme mode differences require different Gain and Tone control treatments to achieve a recognizable and iconic sound. In other words, it may require some dialing of the controls when you are touring through the modes. With circuits capable of these extremes, there is simply no way to avoid this. Don’t worry though, with what you learn in this manual combined with using your ear - you will quickly learn to choose a mode and dial it up to your needs in seconds.
