The Mesa Boogie M6 Carbine is an ultra-fast, super-soulful bass amplifier with a time-tested array of custom-designed MOSFETs (metal-oxide-semiconductor field-effect transistors), but the preamp and driver section are a wholly unique design, creating a very different feel and attitude.

Up front the tube preamp employs a standard tone control string of Bass, Mid, and Treble to shape the basic sound, but the shaping power doesn't stop there. There is a Pull Deep feature found on the Bass control that keeps the low end tight and articulate when pushed in, or it can also enhance the sub-lows and add super-top air when pulled out.

The M6 Carbine Bass Amp also features a Voice control for instant access to global character changes. Here you'll find 4 iconic, distinct sounds and a bypass on a 5-position rotary pot that graphically shows you the EQ curve for each. To the left, positions 1 and 2 dip the midrange in 2 different places, giving you 2 amazing choices for classic round, warm R&B sounds. Turning right past the 12:00 noon Flat position unveils 2 variations on the mid-bump theme. Positions 4 and 5 boost adjacent mid regions to create 2 powerful mid focused sounds that push articulate fingerstyle playing to the forefront of any mix or add the tight drive to Rock. The Voice control can also be triggered remotely using the rear-panel External Switch jacks. Great tone doesn't get any simpler.

The amp head's DI Level and Master controls make adjusting your playing volume levels quick and easy on stage. The DI Level features both post- and pre-Tone control options, with post being the default (pushed in) setting and Pull Pre activating the pre setting that bypasses the entire preamp. A Tuner Mute pull pot is added to the Master Output control for silent tuning in live or studio applications. This feature can also be triggered remotely from the rear-panel Function Switch jack labeled Mute.

The Rear Panel follows suit with simplicity dictating the layout of the essential features every pro rig should include. Tucked securely between the intake/exhaust vents sit the Function Switch jacks and the speaker outputs. The Function Switch 1/4" jacks provide switch ports to control the Front Panel Voice feature and the Tuner Mute. Connecting any grounding (tip-to-ground) logic switch here will trigger the desired Voice setting or the Mute. This functionality allows settings to be stored under programs in a master external switcher. The speaker outputs use stage-ready Speakon universal connectors, which accommodate both standard 1/4" phone type and Neutrik Speakon locking plugs. A Speaker Impedance switch keeps things in the Output section properly matched and allows you to select between 8- and 4-ohm loads or switch down to 2 ohms for full power with these low-load settings.

The Mesa Boogie M6 Carbine takes all the features you're looking for and combines them with a signature sound that's fast, accurate, and”best of all”easy to dial.

mesa boogie m6 carbine

By jim

from north idaho

What can I say? I have played bass for over 20 years for lots of bands and recordings. I have NEVER had the sound I wanted until now. The m6 carbine in its simplicity is pure beauty and refreshing. From crisp clear cleans to gritty dirty. I love the sounds. Articulate for fast licks. Full and rich tones. I cant say enough about this head. The guys at Mesa Boogie have done it this time. At practice my lead guitar player showed up with a brand new 120watt tube ̴_ stack from another company. I felt bad as all of his hours researching were pummeled into submission as the m6 totally dominated the airwaves. I am not just talking about volume I am talking about the way the voicing cuts threw the mix. If you just want to prance around the stage and pluck your bass with one finger this is not the head for you. This is the head for the bass player that wants to play with authority and aggression. They should have called this head the locomotive because it hits like a train. Do yourself, your band and your fans a favor. Get one now.

A Real Power House

By Bassman

from Boca Raton, FL

I changed basses and the sound was not there with my old gear. I tried the Mesa M6 Carbine and it was incredible. In 41 years of playing bass, this is the first amp I had to turn down the settings. It has power and more. This amp rivals any of the power amps from the late 1960's and up. Tone quality is also great. I paired it with the Mesa Power House 2x12 cab. The two 12's have a crushing sound, and pound at your chest. This is a for real pro studio or live amp. I am more than satisfied with this made in America amp. Get one, you wont regret it.

KILLER tone and simplicity !!

By Mike B.

from United States

The Mesa Boogie M6 Carbine is simply amazing. When I plugged a jazz bass into it at Guitar Center, I couldn't believe how incredibly warm sounding this amp is. It sounds like a tube amp, BUT it's attack is LIGHTNING FAST. I play a Peavey Cirrus through this amp and I'm in heaven. It just doesn't get much better. I have NEVER had this amp over 3 - It is SOoo loud ! This is one of the EASIEST amps to use. Mesa Boogie quality, tone, and simplicity.

Mesa Boogie M6 Carbine


from Rochester, NY

Bass, treble, and mid controls make it easy to setup. Make changes on the fly with the mid scoop or boost knob. Lots of power and tone. This amp is very loud. Ideal for live or studio work.

By Mark Woodruff

from Rockwall, Texas

First, let me begin by saying Mesa Boogie is very modest about 'power labels' on their amps. This [600 watt] bass head dominates others at twice the power. The M6 Carbine is all you will ever need in terms of power and playability. After finding my way through many combinations including, but not limited to, SWR, Trace Elliot, and Ampeg...I finally found what I�ۡ���m looking for in Mesa Boogie! The M6 is THE BOMB! I run the M6 through an early model Mesa Boogie R5410 single cabinet which has 4-10's and 1-15, it shakes the ground beneath you! This bass head offers CHEST THUMPING LOWS and great tone shaping capability. What can I say that hasn�ۡ���t already been said in other reviews, this is an excellent product and I wholeheartedly give it five (5) generous stars in every category. CHEERS to Mesa Boogie (AMERICAN-MADE PRODUCT) for making a killer bass head!
