Big Mesa/Boogie Bass Tones!

Mesa/Boogie expands their bass amp line with the M6 Carbine. Mesa/Boogie bass amp fans will recognize the familiar tone of the M6 Carbine (it was previously known as the Fathom), and it incorporates the same time-tested combination of custom-designed MOSFETs that are used in the other Mesa/Boogie bass amps. But this guy incorporates a different preamp and driver section for a new feel, not to mention more attitude. Craft bass tones that punch through even the most cluttered mixes with the M6 Carbine from Mesa/Boogie!

Mesa/Boogie M6 Carbine Rackmountable Bass Head at a Glance:
  • Tone shaping on the front end
  • Versatile controls for a wide range of sounds
  • DI for studio or stage
  • Rear panel
  • Effects loop and more

Tone shaping on the front end
There's no shortage of sound-shaping capabilities with the M6 Carbine. Up front, the tube preamp utilizes 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. It can also enhance the sub-lows and add super-top air when pulled out.

Versatile controls for a wide range of sounds
To complement the tone-shaping on the front end, the M6 Carbine is also loaded with a 5-position EQ switch with a voice control for instant access to global character changes. Here you'll find four iconic and distinctively different sounds and a bypass on a 5-position rotary pot that graphically shows you the EQ curve for each. To the left, positions one and two dip the midrange in two different places giving you two amazing choices for classic round, warm R&B sounds. Turning right past the 12:00 flat position unveils two variations on the mid-bump theme. Positions four and five boost adjacent mid regions to create two powerful mid-focused sounds that push articulate finger-style playing to the forefront of any mix or add the tight drive to rock. Great tone doesn't get any simpler!

DI for studio or stage
Every bassist needs a DI from time to time, and of course the M6 Carbine has one that's both easy to use and tonally flexible. DI level and master controls make adjusting your playing volume levels quick and easy onstage. 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 direct output consists of a standard 3-pin male XLR jack and a ground lift for the circuit to chassis ground connection. The effects loop is in series with the main signal and can be bypassed with the switch located above the send jack. The tuner out jack will feed a signal to your outboard tuner and you can use the front panel pull mute feature located on the master control to mute the signal for silent tuning. The mute can also be remote triggered by connecting a grounding footswitch to the rear panel function switch labeled mute. The M6 Carbine takes all the features you'll ever need and combines them with a signature new sound that's fast, accurate, and best of all, easy to dial.

Rear panel
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 allows settings to be stored under programs in a master external switcher. The speaker outputs utilize stage-ready speakON universal connectors which accommodate both standard 1/4" phone type and Nuetrik speakON locking plugs. A speaker impedance switch keeps things in the output section properly matched and allows you to select between 2-, 4-, or 8-ohm loads.

Effects loop and more
The effects loop is in series with the main signal and can be bypassed with the switch located above the send jack. The tuner out jack will feed a signal to your outboard tuner and you can use the front panel pull mute feature located on the master control to mute the signal for silent tuning. The mute can also be remote triggered by connecting a grounding footswitch to the rear panel function switch labeled mute. The M6 Carbine takes all the features you'll ever need and combines them with a signature new sound that's fast, accurate, and best of all, easy to dial.

Unbelievable!

Had been an ampeg guy and was looking for something with a little more flavor. Started researching mesa and the M6. Reviews and discussion led me to Mesa. Long story short, this head is incredible. The buttery tone is warm, clean, and packs a very tight punch. Mesa products aren't cheap but are absolutely worth every cent. This will be the backbone of my rig and sound for years to come.

"Packaged Power"

Now I have both the M3 Carbine and the M6 Carbine and it has raw power to spare. You have the option of playing 8,4, or even 2 ohms by using the toggle switch in the rear. BOth amps have great tone, but the M6 offers more features. Man, hurry up and get to a local dealer and try one. You don't have to open the volume wide open to hear and feel the warmth and tone. My fellow band members feel the warmth too. Don't take my word, check for yourself and decide.

I bought my Mesa bass amp 12 years ago after playing everything on the market. Only the Mesa delivered the tone and power I need for the diverse styles I play.
