The Best of Mesa's Preamp Technology

Sporting two fully independent channels with six style modes, the Mesa/Boogie Mark Five: 25 tube amp head gives you legendary Mark Series preamp tone combined with Mesa's proprietary Dyna-Watt 2 x EL84 output section. This Mark Series amp gives you maximum portability and responsiveness. Dial in everything from sweet cleans to roaring leads with extra midrange crunch and aggression when you push the EL84 power tubes hard. Factor in the built-in Cabclone speaker-emulated direct output, and you have an amazing gigging and recording amp with the Mesa/Boogie Mark Five: 25 tube amplifier.

Channel one takes you from clean to crunch

The Mark Five: 25's first channel is a rhythm player's sonic playground with clean, fat, and crunch modes serving up an amazingly wide range of tone. Use the Multi-Watt power switch to flip between 10-watt mode for more breakup at lower volumes or 25-watt mode for more headroom and a different playing response. The powerful mid-boost control is all you need to push your tone to the front of any mix.

Channel two brings you legendary Mesa lead tone

Three switchable styles give the Mark Five: 25 everything you need for epic lead tones. Choose from Mark IIC+, Mark IV, and Xtreme modes for three distinct flavors of sonic aggression with switchable 10-watt/25-watt operation for adjustable response and power amp breakup. From smooth and liquid to roaring and edgy, the Mark Five: 25's lead channel gives you more sonic flexibility than most 2-channel amps provide in total.

Built-in Cabclone - achieve awesome tone without a speaker cab

The Mark Five: 25 packs an indispensable tool for gigging guitarists and an outstanding studio tool, too: a built-in Cabclone internal amp load and speaker simulator. It provides an incredibly realistic speaker-emulated direct output to plug right into the sound system or recording chain. You can still use it in conjunction with your favorite speaker cab, but gigging guitarists at Sweetwater also know what it's like lugging a speaker cab along with the rest of your guitar rig. Ditch the speaker cab and just roll up to the gig with only your Mark Five: 25 and your guitar! You'll be cutting down on stage volume, too, which will help give your band a tighter live sound.

Mesa/Boogie Mark Five: 25 Tube Amplifier Head Features:

  • 2-channel, 10-/25-watt tube amplifier head
  • Gives you the same legendary preamp tone as Mesa's Mark V, Mark IV, and Mark IIC+ preamplifiers
  • 2 channels with 6 total style modes give you an amazingly wide range of tone to explore
  • Built-in Cabclone speaker simulator and internal load box give you awesome direct tone
  • Ultra-rugged design with all-aluminum chassis
  • All-tube spring reverb can be applied to each channel independently
  • 2-button footswitch (channel 1, channel 2, and EQ) and slipcover included
  • Important Notice for International Customers: Mesa/Boogie products sold by Sweetwater are intended for use within the United States. We are unable to ship any Mesa/Boogie products outside of the US.

An amp that finally does it all!

This amp is something else! I play in a power trio focusing primarily on swing and power blues with some heavier tunes as well, so I need a great clean channel with a little bite and a channel that will give me some good saturation yet still be articulate.
I owned a Rocket and a Heartbreaker and can honestly say the Mark V definitely has the best clean channel Ive ever found on a Mesa. I'm running through a 2x12 with a V30 and a G12-80 and a 10x12 with Celestion alnico golds. I have it set to clean and the gain almost dimed (around 4:00). I'm running it at 25 watts with the volume at around 9:00. On channel 2 I'm using the Mark II C+ setting with the gain extremely low (8:00) and am getting unity with the volume at 4:00 but the power set at 10 watts.
Now here's the kicker…the 5 band EQ. Being that it's "assignable" on the clean channel I'm using it as a treble booster with the footswitch however on channel 2 I have it set for "always on" and it cleans the signal up nicely, eliminating some of the "bottom end mud" giving me that nice, smooth Gary Moore sound out of my '99 Les Paul.
Bottom line, this is no bedroom amp, in fact it has replaced my SLO30 because not only can it hang with the volume, but the assignable EQ and assignable power section give me ultimate control of my unity volume and tone for both channels.
Money well spent and special thanks to Joe Schafer for his help in my selection!

1 amp to rule them all!

I was hesitant to purchase one of these. But I did some trading and got one NIB w/ the 12" sealed Mesa Cab. After spending some time reading the manual fully and sitting down to 'learn it' I must say, I think if I had to only own ONE amp this would be it. I can go from super glassy cleans to a high gain metal with the push of a footswitch. I honestly didn't know if I would like the graphic EQ or not, but honestly, it has helped me 'tweak' in the right settings. Very happy. I haven't pushed it to the 25w setting as at home the 10w is more than enough. I still have some more exploring to do on the amp but I think this is one I will keep for a lifetime. Thanks Mesa!

Versatile, Loud and All Mine

This amp ticks all of the boxes for me. Great cleans, great edge of breakup tones and above all else, gobs of chewy distortion.

I was stuck choosing between a handful of choices for what amounted to being my first tube amp. I had always dreamed of owning a Boogie since I was a youngster. I am glad I made the choice that I did. I was worried about not being able to try before I buy but in the state of the world today, it just wasn't possible. Upon arrival, all fears subsided upon hitting that first chord.

The amp sounds great even with the master set at about .1. This is important because anything past 8 o clock on the knob had me making sure my life insurance hadn't lapsed without my knowing.

I paired up the amp with the Thiele cab and can report the union is exactly what I was looking for. Great low end without being flubby.

All in all, I'm over the moon with this purchase and can't help but smile every time I power this thing on.

Supreme little monster!!

In an attempt to keep this short and sweet, it's difficult to do this amazing amplifier justice in a short user comment.
Received my custom ordered Mesa Boogie Mark V:25 (leather handle instead of rubber) from Sweetwater all safe and sound.
All I can say is WOW!! Each of its two channels and all 6 of its modes, pure tone. 2 beautiful cleans, 1 sweet crunch, and OMG 3 ripping gain modes. Side note: very few YouTube videos accurately reflect just how ferocious and capable this little monster can be. From classic rock crunch to harmonic laden high gain articulate grind. Most people have the bass turned up to "normal amp" levels...NOT how to adjust most Mesas. Overall it's miniature in size only but is absolutely packed with features, flexibility and most importantly: tone! Also, don't let the 25 watt rating deter you, it's very powerful, easily driving your cabinet of choice. Although it's quite expensive for a "mini" I'd comfortably say its worth every penny. Very highly recommended.
Music background: Hack

It's hard to imagine a more quintessentially modern guitar amplifier than a Mesa/Boogie, and when Sweetwater guitarists want high-gain tone, Mesa is where they start. One thing we love about these amps is their sheer versatility, such as the massive range of tone you get from each channel, the freedom to use the tubes you love, onboard CabClone cabinet emulation, and MIDI control. And it's not just guitar amps - Mesa/Boogie's bass amps and pedals are equally cool. What's more, thanks to our incredibly close relationship with Mesa, you can even customize your own amp right here on Sweetwater's website! Get the sound and style you want from your next amp, with a Mesa/Boogie from Sweetwater.
