This is the same Trans-Class™, ultra-fast, super-soulful amplifier that has had so many bassists reconsidering their Tone. The CARBINE expands the MESA Family of Bass amplifiers with an exciting voice that’s super fast and extremely focused. The output section relies on the same time-proven array of custom designed mosfets used in the M-Pulse, Big Block and Titan models, but the preamp and driver section create a very different feel and attitude.  

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 or, enhances the sub-lows and adds super-top air when pulled out.

PULL DEEP: Convenient PULL DEEP feature allows you to select two ranges of fundamental for the BASS control. Normal (Pushed In) accentuates tight, percussive bottom that tracks with accuracy and cuts through a mix. Pull DEEP (Pulled Out) shifts the low end, enriching the sub-low and extreme-top to create warm, breathing air the whole band can ride on.

The CARBINE also features a new 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 1 and 2 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 noon FLAT position unveils two variations on the mid-bump theme.  Positions 4 & 5 boost adjacent mid regions to create two powerful mid focused sounds that push articulate fingerstyle playing to the forefront of any mix or add the tight drive to Rock. 

VOICE FEATURE: Powerful 5 position VOICE control gives you all the power of a parametric EQ without the fuss. VOICE allows instant selection of four distinctly different EQ curves and Bypass. Choose position 1 or 2 that cuts midrange in two different frequencies for the ultimate warm, scooped R&B vibe. Or boost midrange in specific spots that enhance tight finger-style or Rock work with position 4 or 5. Can also be triggered remotely using the Rear Panel External Switch jacks.

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 ¼” 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 ¼” 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 8/4 Ohm loads or switch down to 2 Ohms (CRITICAL when loads of 2 Ohms are used) for full power with these low load settings.

To the right of the air intake vent are the EFFECTS LOOP and DIRECT OUTPUT sections.  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.

FUNCTION SWITCH JACKS: Five ¼” Function Switch Jacks are provided for remote triggering of the VOICE feature and the TUNER MUTE allowing you to build programs under a remote switching system for easier access in stage applications.
