This Ultra-versatile Mesa/Boogie Tube Head Has it All!

The Mesa/Boogie Mark V guitar amp head will take you on a tonal journey through the company's illustrious history with some new capabilities thrown in. Whether you're craving the sound of the Mark I's high-gain cascading preamp or the fat, wide tone of the Mark IV, the Mark V delivers. At Sweetwater, we've been blown away by what this ultra-versatile guitar amp head is capable of. The Mark V lets you dial up anything from tweed-like tones to British crunch to the highly-coveted trademark Boogie overdrive. Featuring a 5-band EQ, Multi-Watt and Simul-Class power, and three channels of sonic mayhem, the Mesa/Boogie Mark V guitar amp head will give you all of the clarity, crispness, and punch that you can handle!

Mesa/Boogie Mark V Guitar Amp Head at a Glance:
  • Three channels give you plenty of sonic possibilities
  • Three voicings on each channel for even more tonal versatility
  • Graphic EQ provides you with a wide range of sound-shaping options
  • Multi-Watt and Simul-Class power let you control your amp's personality
Three channels give you plenty of sonic possibilities

The Mesa/Boogie Mark V guitar amp head provides you with three channels of sonic possibilities. Channel one gives you a range of clean tones that blend vintage tube characteristics with a shimmery high end, resulting in a crystal-clear, boutique-like tone. Channel two is the right choice for when you're looking for a thick, throaty crunch with tight attack. Channel three gives you the iconic high-gain sound that became associated with players like John Petrucci, James Hetfield, and Kirk Hammett in the 1980s.

Three voicings on each channel for even more tonal versatility

In addition to the Mesa/Boogie Mark V guitar amp head's three channels, you also get three distinct voicings for each channel that are controlled by a simple mini-toggle switch. 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. Make no mistake - you'll spend hours upon hours experimenting with different gain and tone control treatments while sifting through the Mark V's voicings, recreating some recognizable tones from Mesa/Boogie's past (and inventing some new ones of your own).

Graphic EQ provides you with a wide range of sound-shaping options

While the Mesa/Boogie Mark V guitar amp head gives you standard tone controls, you also get a 5-band graphic EQ for even more sound-shaping. By using the Mark V's graphic EQ in conjunction with a high-gain sound, you'll be able to perfectly replicate the classic V curve that became a staple of heavy metal guitar tone in the 1980s. Each channel is fitted with a mini-toggle to turn the graphic EQ on or off. You can even make the EQ footswitchable!

Multi-Watt and Simul-Class power let you control your amp's personality

The Mesa/Boogie Mark V guitar amp head lets you alter the amount (wattage) and type (configuration) of power each individual channel will be coupled with, giving you unprecedented control over the character and personality of your amp. Lowering the wattage of the Mark V decreases its headroom, making it easier to push it into overdrive. The Mark V is also wired so that it is capable of operating in both a Class A triode configuration and/or a Class A/B pentode configuration, depending on which wattage you select. You can use two power tubes to operate the Mark V in Class A mode at 10 watts, emphasizing even-order harmonics for a sweet tone with a soft, rich purring quality, or you can use two tubes running in A/B mode at 45 watts, emphasizing odd-order harmonics for a harsher sound. The best part, however, is that you can use four tubes running in both Class A and Class A/B modes simultaneously at 90 watts, giving you the best of both worlds!

Mesa/Boogie Mark V Guitar Amp Head Features:
  • 3 channels give you plenty of sonic possibilities
  • 3 voicings on each channel for even more tonal versatility
  • Graphic EQ provides you with a wide range of sound-shaping options
  • Multi-Watt power gives you variable wattage control
  • Simul-Class power lets you alter the amp's power configuration
  • True hard-bypass switch removes FX loops, output level, and solo level controls from the signal path
The Mesa/Boogie Mark V guitar amp head - an all-tube amplifier with a stellar legacy and serious tone!

10 amps in one box

I always had Mesa Boogie, in particular studio preamp and 50/50 tube amplifier which gave me an outstanding power and the typical Mesa sound to play killer rock/metal riffs, but I was not totally satisfied by the clean channel; Mesa equipments are are so particular and its components interdependent that I was not able to have a very clean channel if I wanted a very aggressive lead one. All of this together with my gear aging convinced me to approach the Mark V, a choice I have evaluated for a long time due to its significant cost. Mark V is far above any expectations, the possibilities and sounds are virtually infinite, don't think for a single moment this is just a heavy metal amp, I would not be surprised to see free-jazz guitar players touring with this tube masterpiece. It's a professional equipment and, this has to be said, not easy to use due to the dozen available settings, you will have to work to find your sound, but once you do the Mark V will definitely help you to play better because you surely pay more attention about what you are playing, its cleanliness and high defined sound will encourage you to refine your technique.

Boogie Till You Drop!

Every time I turn this amp on, I found new creamy tones that just make me want to keep playing for hours. My ES-137 rocks through this bad boy, my Stratocaster has been given new life and my Les Paul is delivering tones that give me goose bumps all over! Everything about the amp's construction is top shelf too. Very responsive controls and a seemingly unlimited number of tonal options. This amp is for any type of music as well. I wish I could describe the tones in a way that would do this amp justice. You really have to hear it for yourself and I'm sure you would be as blown away as I have been. I am playing through a 2X12 horizontal Rectifier cab which deserves a whole other review in itself. I am glad I was able to purchase this amp through Sweetwater as they have been nothing short of awesome in their customer service. They really know how to take care of their customers. Sweetwater has a customer for life in me!

Buy It...You won't regret it!

One would best describe me as a frustrated living room musician, who has been playing guitar off and on for 30 years or so. For me buying this amp was kind of like buying a Maserati to drive to church and was way more than what I could ever need, but being one who can only be satisfied with the pure tones I was striving to achieve with a Fender Superchamp and a Line 6 Pod effects processor.......and failing miserably.......I decided that I had to spend the money.......I'm glad I did! At first I had some buyers remorse, because I was way over my head with all that one can do with this beauty, but now after several months of "getting to know her" I am totally head over heals in love and am convinced I can not live without her. Channel 1 has a variety of deep crystal clear tones that you have to hear to believe. Channel 2 is the old style rich but mellow distortion that is the absolute best for my Santana cover songs and Channel 3 is.....well's just mind blowing!Sweetwater was absolutely great to deal with too. The first head was damaged by being dropped during shipment. But no worries, everything was taken care of with just one phone call to my rep Chris, who shipped out another one the next day via priority express!

What a great sounding amp!!

I was using a Marshall TSL100 with a Gmajor and a bunch of pedals through a Voodoo Labs GCX and ground control floorboard. The marshall fried so it was a good time to try something different. I loved the Marshall but it just didn't quite get there. I got the Mark V and was immediately blown away by the clean sound. I can get the legit fender twin clean sound with my tele! COOL! Channel 2 is great for good solid rythum crunch sound. Channel 3 was the HOLY CRAP channel. It takes some tweaking as this amp is very versatile. This is my first Mesa amp but I am a Marshall convert now and will always play mesa. I play at church doing worship...this amp is way more than I need but it sounds great there. In large festival venues it really shines. Look at all the pros who use these things. That says it all. No mods needed. An added bonus I didn't know about until I unpacked it was that it has channel, eq, and solo jacks on the back which integrate with the GCX loop switcher... no breakout box needed from the footswitch jack. Just to recap...You can get the chimey Fender clean, the brown Marshall sound, the total rectified high gain, and most anything in between. Forget about modelers - they all come up just short. This thing really can cover it all. Sweetwater was great too as always and had it at my door overnight! I Love this amp! the golden tone has been found! get one.
