While many guitarists have a need for speed, bassists seem to crave power—the more the better. But power alone isn't enough. Definition, accuracy, presence and a musical EQ are essential in getting big power to the ground so you can create a great bass sound—one that can drive the band and move the crowd.

A bigger-block version of the widely acclaimed Big Block 750, the rackmountable Mesa Boogie Titan V12 Bass Amp Head is a straightforward, easy to dial preamp of footswitchable, genre defining, bass magic. The V12s' identical all-tube preamps can be used with one instrument to create a channel-switching platform or, can be switched to a Dual-Input, two-channel configuration for use with two separate instruments in a stage environment. Swap instruments, hit the footswitch and you're ready to go. This quick-change preamp makes the Big Block Titan a great choice for the bassist who also doubles on Key Bass, providing footswitchable hot-swap capability while wearing the stringed instrument.

A traditional wide-band harness of Treble, Mid and Bass controls is enhanced by the musically accurate shaping power of the semi-parametric Active Mid band. Mix up a sound with the sweet blend of the standard harness and fine-tune it with the frequency specific Active Mid band.

Each channel serves up a dedicated Gain and Master control for the footswitchable tube Overdrive allowing you to dial in the perfect amount of tube saturation. From a soft-clip to a medium growl on up to full-blown high gain sustain—the bass head's full range is available for you to explore.

At the heart of the Big Block Titan's massive power lies the Simul State tube-driven MOSFET technology. Every note drips with soul as it flies dynamically from the tube Inputs and Driver stage, to the fleet of 22 custom designed high-power MOSFETs. The stunning torque of this 1200-watt motor is apparent in the Mesa Boogie Titan V-12s' sonic footprint. Instantaneous attack, shocking clarity and the ability to late-brake and stop on a dime—even at high revs—put you out front and in charge of the time domain, letting the rest of the band thrive on your role as anchor.

So when your gig requires you to have big venue capability as you lead the rhythm section, don't take a ride that'll come up short.
