Mesa Boogie Mark Five: 25 Tube Guitar Amp Head

IT TOOK 40 YEARS of Randall Smith's experience designing high-performance tube amplifiers to get this much TONE under one roof and keep it easy to dial. More than a collection of amplifiers, the MARK V 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.

9 AMPLIFIERS IN 1 WITH 9 PATENTS DEFINING A HISTORY OF INNOVATION
Like its predecessor the MARK IV - in steady production for over 19 years - the MARK V is an investment in your musical future. The 9 preamps and 3 power amps it contains trace their roots back to the beginnings of amplified guitar. Yet while their lineage is time tested, the performance they unleash is brand new and cutting edge. This collection of amps will propel you through any musical style and project, and band any era of your development with confidence and command.

3 FOOTSWITCHABLE CHANNELS, 3 MODES PER CHANNEL
3 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, which is responsible for the voicing of each Channel.

MULTI WATT POWER
The Mark V features our popular channel assignable Multi-Watt Power that determines the amount (wattage) and type (configuration) of power each preamp channel will be coupled with to create a classic sound via independent channel switches. Any amplifier's sound is 50% preamp and 50% power, so these switches are responsible for a large part of a given Channel's personality and feel. The choices repeat for all 3 Channels and they are 90W, 45W and 10 W. Using the switch is simple… just select the power/feel you want for each Channel, keeping in mind that the greatest headroom, focus and authority will always be found in the 90 watt position.

ICONIC BOOGIE 5-BAND GRAPHIC EQ
Each Channel is fitted with a mini-toggle to select the 5 Band Graphic EQ, but the fun doesn't stop there. The MARK V gives you the choice of two ways to utilize the power of the Graphic EQ for each Channel! The mini-toggle within each Channel (center mini-toggle) allows you to decide whether you want the EQ on all the time in that Channel, off all the time or activated by the EQ button on the Footswitch.

A separate set of mini-toggles to select SLIDERS or PRESET for each Channel (located in the left side of the Graphic EQ section) allows you to select whether you will use the actual SLIDERS to shape your individual EQ curve or, a PRESET contour based on the ever- popular "V" curve. The ability to choose between these two options when assigning the Graphic EQ to your sounds gives you ultimate flexibility when dedicating the Channels. By combining subtle blends of the Tone controls with the EQ options, virtually any sound you can imagine is at your fingertips.

CHANNEL 1
This Channel incorporates our best two Clean Modes ever, CLEAN and FAT from the MARK V. These Modes offer two musically useful flavors of this sparkling low gain voice that benefit from 35 years of continuous refinement and take Clean sounds to a dynamic, new touch-sensitive plateau. A third “crossover” Mode (CRUNCH) is also showcased here in Channel 1 and again, it’s taken directly from the acclaimed MARK V.

The CRUNCH Mode covers the mid-gain ground between Clean and mildly overdriven and ultimately, with this power section, on up to the higher gain sounds of its namesake. CRUNCH by itself is worthy of—and delivers more than—most stand-alone amplifiers. Also, here in the FIVE: 25, CRUNCH is enhanced by the ability to blend in more power section clip at lower volumes due to its lower wattage range. The EL84s accentuated top end harmonic content adds a nice openness to lower GAIN settings and Brit-voiced shred to the higher GAIN range, making CRUNCH even more applicable and valuable. You will likely find it one of the most useful Modes of all in this MARK’s arsenal.

MID BOOST
Mark Five 25 Mid Boost
From 0 to 5.0 on the MID/BOOST you will find the normal range of a standard MID control in a condensed form. From 5.0 to 10 on the MID/BOOST a wonderful graduation of overdrive possibilities unfold that enhance gain over a wide midrange spectrum and saturate with increasing thickness.
Channel 1 in the MARK FIVE: 25 is also fitted with an additional (patent applied for) MID/BOOST feature that increases both the gain and flexibility in all three of its Modes. What was a switchable On/Off Gain Boost feature on the original MARK I appears here as an adjustable MID/BOOST found on the MID Control. From 0 to 5.0 on the MID/BOOST you will find the normal range of a standard MID control in a condensed form. From 5.0 to 10 on the MID/BOOST a wonderful graduation of overdrive possibilities unfold that enhance gain over a wide midrange spectrum and saturate with increasing thickness. The dial-to-taste smooth, warm overdrive found in the MID/BOOST transforms Channel 1 into a full featured (high gain) amplifier all its own and offers HUGE potential for great solo and overdriven rhythm sounds across a wide range of styles.

CHANNEL 2
The top Mode of Channel 2 (the MK IIC+ Mode) is an exact recreation of the iconic MARK IIC+ LEAD Mode and offers the blistering midrange focus and searing top end of this classic 30 year-old circuit. Its urgent attack and tight midrange focus provide the perfect canvas to create, especially huge Rock and Metal sounds, with another iconic MARK feature... the on-board Boogie Five-Band Graphic EQ. Many Heavy Rock aficionados find the MK IIC+ Mode with the EQ employed their go-to sound for aggressive high gain rhythm work. For the rest it provides an articulate, singing high gain voice with tons of mid-focus clarity from which to craft your signature Lead voice.

Channel 2’s middle Mode, the MK IV Mode, is another exact recreation, this time of the MARK IV’s “Lead” Channel and it appears on both the 6L6 MARK FIVE’S Channel 3 roster and here on the MARK FIVE: 25. This MARK IV Lead Mode is fatter and creamier than its mid-accentuated brother, offering a warmer voice that’s great for both single note soloing and high gain chording. It’s nicely juxtaposed to the pointed, more forward voice of the IIC+ and is supremely balanced and full bodied. Played with or without the Five Band EQ, the MK IV Mode is a great all around choice for so many styles, low or high gain, and would be ideal even as the only Lead Mode. Its warmth, balance and easy to play feel are the sonic anchor for Channel 3 in the EL84 powered MARK FIVE: 25.

The XTREME Mode (bottom Mode) is also a faithful duplication and taken directly from the 6L6 MARK V. It definitely lives up to its name and delivers the radical dose of high gain infused with extra harmonics and even more urgent attack than its cousin upstairs, the IIC+ Mode. This hyper reactive voice jumps at the first hint of pick attack and roars with aggression. It’s further antagonized by the similar response of the EL84 power tubes here in the FIVE: 25 with their fast attack, higher mid frequency and relative lack of sub-low bottom end. XTREME shreds, grinds and thrashes like the angry teen it is circuit-wise and whatever it lacks in nuance, it makes up for in brash attitude. It’s very fast, forward and furious and should be used in musical environments where you don’t care if you offend and/or dominate... and in fact, may even be the goal.

LEGENDARY BOOGIE 5-BAND GRAPHIC EQ
Mark Five 25 5-Band Graphic EQ
Legendary BOOGIE 5-Band Graphic and Multi-Watt Channel Assignable Power
The on-board 5-Band Graphic EQ has been an iconic trademark of MARK Series Boogies since it first appeared on the MARK I back in 1970. The shaping power of this feature can’t be denied, especially when combined with the MARK II and IV’s tight, mid-focused gain sound. In the ‘80s the classic “V” setting of the Graphic EQ on MARK II and III models became an instant Classic. The Graphic EQ comes at the very end of the signal chain so you can shape the final sound with the only consideration being how much of a certain frequency your speakers, cabinet – and ultimately your ears – can handle.

MULTI-WATT CHANNEL ASSIGNABLE POWER
To the right of the Graphic EQ SLIDERS are the Multi-Watt Channel Assignable Power switches for each Channel. These allow selection of either the full 25 watts of Dyna-Watt power with its more-than-rated punch and impressive burst of headroom on the attack, or the brighter and oh-so-clip-able 10 watts of Class AB Triode power. Dyna-Watt is the choice for most gigging or rehearsing with others and provides the maximum volume for clean sounds and the tightest tracking response for high gain rhythm work, especially in the low end.

The 10 Watt setting flips the 2xEL84s over to a CLASS A/B Triode wiring configuration that offers an opposite power response to Dyna-Watt along with greatly increased clip-ability. It produces a skinnier, slightly brighter response and is the same low power scheme used in our Mini Rectifier 25 for its ability to track many styles and it’s the perfect fit for the 6 versatile preamp Modes here in this MARK rendering as well. The 10 Watt setting is great for lower volume practicing, rehearsing and recording and allows more use of the power section as a gain source, enabling you to reduce the preamp’s GAIN Control settings and explore the old school approach to achieving tube overdrive... power saturation.

BUFFERED SERIES FX LOOP
Mark Five 25 Effects Loop
The first feature of note starting at the far left of the rear panel is the Series, Buffered, Tube FX LOOP. The MARK FIVE: 25 includes a HEADPHONE Output for personal enjoyment of the amplifier when it is not possible to play through a speaker.
The Buffered, Tube FX LOOP is the interface point for outboard processing and it provides a junction between the preamp and power section. The LOOP performs well with both Rack and Pedal type outboard gear with the obvious exceptions being those effects that work better on the INPUT of an amplifier (Wah, Compression, Gain and Overdrive Pedals, Envelope Filters, etc.). Since it is buffered, you can use multiple units in line and relatively longer lengths of cable (25 feet or less) before hearing too much degradation in signal.

HEADPHONE OUTPUT
The MARK FIVE: 25 includes a HEADPHONE Output for personal enjoyment of the amplifier when it is not possible to play through a speaker. This jack derives its “speaker simulated” signal from the included CABCLONE D.I. feature and delivers a surprisingly good rendering of the FIVE: 25’s sound and feel to your headphone set of choice.

ALL-TUBE, SPRING REVERB
Mark Five 25 All Tube Reverb
The Mark Five: 25 has independent REVERB Controls for each Channel. This allows different amounts of the all-tube, short-spring analog Reverb to be dialed in for each of the Mark Five: 25’s 2 Channels.
Next up are the REVERB Controls and there is an individual MIX for each Channel. This allows different amounts of the all-tube, short-spring analog Reverb to be dialed in for each of the MARK FIVE: 25’s two Channels. Anything from a subtle background ambience to a fully drenched effect can be dialed according to taste and musical style.

CABCLONE D.I.
MArk Five 25 Built in CabCLone
On-board CABCLONE D.I. Cabinet Simulation feature - This built-in magic allows you to capture a wonderful representation of the sound and feel of the MARK FIVE: 25 direct to a Console, Converter or even direct to a Recorder without the need to mic up the speaker.
And last but DEFINITELY not least, is possibly the coolest feature ever to grace a MESA Rear Panel, the on-board CABCLONE™ D.I. and Cabinet Simulation feature. This built-in magic allows you to capture a wonderful representation of the sound and feel of the MARK FIVE: 25 direct to a Console, Converter or even direct to a Recorder without the need to mic up the speaker.

Taken directly from our acclaimed stand-alone CABCLONE, this compensated D.I. (and HEADPHONE Output) does an incredible job of capturing the signal from the SPEAKER OUTPUT and turning it into direct injection gold. The four elements here allow for use both with a live speaker and without, so you can blend the direct and a mic’d speaker cabinet if you so desire. The CABCLONE section features switches for SPEAKER Status (OFF/ON), CABINET Style (OPEN BACK/CLOSED BACK), GROUND (GROUND/LIFT; Pin 1 Float) and an XLR BALANCED Output. This array of controls comprises perhaps the most valuable and welcome feature set on any MESA amp and expands both the functionality and enjoyment potential many fold. The MARK FIVE: 25 is the first of our amplifiers to include this powerful tool built right in for speedy and convenient live use or recording applications without sacrificing authenticity and Tone.
